III GL DESCRIPTION

[0043] In the late 1980s, the University of California began research with new V-shaped trellis designs which became popular. Although the gable trellis increased yield dramatically and in some cases doubled production, its effective use required labor-intensive shoot positioning and canopy division.

[0044] Solutions to improve the canopy division of the gable trellis included positioning shoots to the trellis arms and leaving the middle of the plant free of foliage to form two fruiting zones along each of the trellis arms. Although the trellis center remains open for only three or four weeks, the canopy division operation was necessary to organize the fruit zone (keeping shoots from heaping up in the bottom of the V) and to improve light during a critical period in the development of fruit buds. Canopy division also allows light into the canopy interior, which is critical for developing fruitful buds for the following year.

[0045] Canopy division is currently a manual process performed by positioning and securing shoots to wires on one trellis arm or the other using vine ties or training tape. Labor costs for such a manual division are prohibitively expensive. Further, manual canopy division tends to break shoots that crisscross each other. Alternatively, canopy division can be performed by placing two moveable wires in the middle of the trellis support cross-arm during plant dormancy, whereby the two wires are pulled over to the trellis arm to divide the canopy. Such moveable wires often fail to properly secure the vines, allowing inclement weather to easily blow shoots out of position and back into bottom of the trellis V. Shoots positioned by moveable wires or by hand can be dislodged and disorganized by high winds and inclement weather.

[0046] To protect such vines from sunburns of canopy and fruit, from fruit ambering, and from rain and inclement weather, growers currently cover the vine’s canopy with plastic until harvest is complete. Such covers slow fruit maturation, reduce the light levels received by the canopy and fruiting zone, and increase the heat, humidity, and condensation in the canopy and fruiting zone. This plastic cover is used for only one season and then disposed, and the cost of the cover and the amount of labor required for installation and reinstallation is significant. The cost of labor and materials, in some cases, exceeds a thousand dollars per acre. The plastic has very low light transmittance and thus prevents sugar and color accumulation in the fruit. [0047] Plant growth regulators, fungicides, pesticides, and foliar nutrients are currently sprayed onto the plants as concentrates (air carrier) or dilutes (water carrier). Both spray types require direct spray up and through the canopy. Spray, which does not come in contact with leaves and fruit, penetrates the vine and drifts into the atmosphere or drips to the ground.

[0048] Provided herein are devices and systems for sunlight delivery, shoot positioning, and canopy division, positioning fruit into distinct zones, managing fruit maturity and quality, and reducing canopy management and harvest labor. The devices and systems may also protect fruit from damaging weather, such as rain, wind, or excess sun exposure. The devices and systems may further provide spray coverage and may reduce or eliminate spray drift. The devices and systems herein represent a leap forward in trellising by enabling improved light management and climate conditions in the vine canopy and fruiting zones. The devices and systems for sunlight delivery, shoot positioning, and canopy division of one or more plants on a trellis herein overcome the deficiencies associated with manually canopy division or moveable wire-assisted canopy division.

[0049] Recognized herein are systems and methods for positioning fruit into distinct zones of plants on trellises that obviate the deficiencies associated with cluster thinning, berry thinning, and harvest.

[0050] The devices and systems herein enable increased crop production and improved fruit maturity and quality by directing growth of shoots parallel to one another and upward until the shoots cascade over the top of the trellis arms. Further the devices and systems herein may reduce or eliminate the need for vine positioning labor and single-season disposable products, and reduce cluster thinning, berry thinning, and harvest labor. Additionally, the shape and positioning of the devices and systems shield and secure the vine from frost, hail, rain, wind and sunburn damage. Further, the shape and positioning of the devices and systems maintain the position and integrity of the plant’s shoots even under high winds. The devices and systems provide a shield that greatly reduces spray drift into the atmosphere and improves coverage of the fruiting zone and foliage. Additionally, as the devices and systems enable the center of the trellis to remain open all season, the interior canopy, fruit wood developing for next year, and fruiting zone are continuously illuminated in some embodiments. Such illumination increases flower cluster numbers and sizes the following years.

[0051] The devices and systems for sunlight delivery, shoot positions, and canopy division described herein may be applied to a variety of trellises or trellis systems, such as T trellises, standalone T trellises, gable trellises, closed gable trellises, open gable trellises, Tatura trellises, or any other trellis or trellis system.

Transmission spectra

[0101] FIG. 11 displays exemplary transmission spectra through plastic panels of different colors. As shown in FIG. 11, panels that were red, orange, and pearl in color allow nearly full transmittance of the solar spectrum at wavelengths longer than about 600 nm. At shorter wavelengths, however, the panels are significantly less transmissive of light. The red panels, orange, and pearl panels significantly reduced transmission of wavelengths shorter than about 600 nm, about 570 nm, and about 470 nm, respectively. This clearly demonstrates that the panel color has a significant effect on the growth character of the light that reaches the plants.

EXAMPLES

Example 1 : Flame Seedless Grapes

[0103] The trellis systems described herein were applied to the growth of flame seedless grapes. Two experiments were conducted on flame seedless grapes located within a few rows of one another. The first experiment involved trellis panels that did not utilize holes, while the second experiment involved trellis panels that include holes and had a boat-like shape. Both experiments were statistically designed as completely randomized blocks with six replications, statistical analysis by analysis of variance (ANOVA), mean separation by least significant difference. Fruit characteristics were measured on five occasions, twice before harvest began and then just prior to each of the three harvests for a total of five samplings. Measurements included berry weight, length, and width, and firmness. Berries were macerated and the resulting solution was evaluated for sugar and acid.

[0104] The potential yield for both experiments are shown in Tables 1 and 2. This was based on counting clusters in each plot. The average cluster weight was 1 pound, vine density was 518 vines per acre, and a packed box weight was 19 pounds. Using this data, the potential yield for each plot was calculated and reported as boxes per acre. There were no significant differences in total potential yield between the two experiments and the coefficient of variation between plots was reasonable (about 10%). The percentage packed treatment values were calculated as boxes packed divided by potential yield (boxes available to be packed).

[0105] This trellis panels in the first experiment (no holes) increased the percentage of fruit packed 40% compared to 24% for the unleafed control. The amount of total fruit harvested for the leafed control was 42%. For the second experiment (with holes), the amount of total fruit harvested was 65% compared to 49% for the control. Both of these treatments were leafed.

[0106] The first and second experiments were in close proximity to one another in the vineyard.

It is interesting to note that the total fruit harvested from leafed control vines in each experiment was similar (42% and 49%, respectively), as shown in Tables 3 and 4. The similarity in results comparing the two experiments adds confidence to the results. It also suggests that the performance of trellis panels utilizing holes was good and likely similar to the original design.

[0107] The result from the first experiment verifies results obtained a year ago. The trellis panels without holes increased the number of boxes picked on the first pick by 77% in this experiment and by 61% in the previous year’s trial. The total harvest for all three picks was also increased, by 16% this year and 11% last year, as shown in Table 3.

[0108] The results from the second experiment aligned nicely with the results from the first experiment. The first pick was 97% greater than control. Harvests from the trellis panels with holes and control treatments were similar on the second pick, but the harvest from the trellis panels with holes was greater on the last pick. The total for all three picks showed that the yield from the trellis panels with holes was significantly higher (32%) compared to the control, as shown in Table 4. FIG. 12 displays harvest yields for trellis panels that include holes and had a boat-like shape in comparison to a control and corresponds to the results displayed in Table 4. As shown in FIG. 12, the holey units resulted in a 40% increase in crop value compared to the control. Grapes coupled to the holey units also ripened earlier in the season and had increased berry sizes, widths, and lengths in comparison to the control.

[0109] In the first experiment, there was no difference in sugar comparing the unleafed first experiment with the leafed control treatment. However, both had significantly higher sugar compared to the unleafed control. This suggests that light was the primary factor, lack of which reduced sugar accumulation in the unleafed control, and that the first experiment was as effective as leafing in providing light.

[0110] The second experiment increased berry weight, width, and length compared to the control. After leafing, shoots and side shoots continue to grow and the improvement in the light environment that results from leafing is lost within a few weeks. But, with the application of trellis panels without holes, the improvement in the light environment continues. There is a suggestion that the trellis panels without holes improve berry firmness, as shown in Table 6.

[0112] This research was designed as a completely randomized block design with four treatments, six replications, and four vine plots. The experiments included controls with no panels, white metal panels, white glittery panels, and red panels. Statistical analysis was by ANOVA and treatment mean separation by least significant difference.

[0113] The red panel delayed early fruit color development, but later fruit color was similar for all experiments. Fruit color was similar for all panels when evaluated on the east and west side of the vine. As with fruit color, the red panel delayed sugar accumulation, but later sugar accumulation was similar for all experiments. Berry firmness, an important sensory quality, was similar for all experiments.

[0114] FIG. 13 illustrates the effect of different colored panels on the time to maturity of Krissy seedless grapes and corresponds to the results displayed in Table 7. As shown in FIG. 13, red panels delayed maturation. However, red panels enhanced fruitfulness is the following year.

L.S.D. 1.3 7.7 Example 3: Comparison of trellis panels for flame seedless and Krissv seedless grapes

[0115] Flowers were counted for both the flame seedless and Krissy seedless experiments to determine the impact of a previous year’s treatments on vine fruitfulness. The statistical design was a completely randomized block with six replications and four treatments. Treatments for flame seedless included a control treatment, a trellis panel with holes, a glitter trellis panel, and a red trellis panel. Treatments for Krissy seedless included a control treatment, a white trellis panel, a glitter trellis panel, and a red trellis panel. Statistical analysis was by analysis of variance (ANOVA).

[0116] There was no difference in flower counts between the east and west cordons for the Krissy seedless cultivar but a highly significant difference for the flame seedless cultivar (which had more flowers on the west cordon). For all cultivars, adequate light is required from May through June for bud differentiation, and some cultivars have a greater requirement than others. Flame seedless is very light-sensitive, which may explain why there would be more flowers on the more illuminated west side of the vine. Krissy seedless is less light-sensitive.

[0117] With Krissy seedless, the red panels significantly increased flower counts compared to the control and white panels. For flame seedless, the fruitfulness with the red panel was similar to the control and both the control and the red panel produced greater fruitfulness than white panels. All of this suggests that the red chromatic plays a greater role in flower cluster differentiation than other colors.

[0118] FIG. 14 illustrates the effect of different color panels on fruitfulness of Krissy seedless grapes one year after application of a trellis panel and corresponds to the results displayed in Table 13.

Example 4: Enhancement of light intensity in vine inner canopies near fruiting zones

[0119] Light was measured on a clear sunny day in the early afternoon using an Apogee

Instruments (Logan, UT) hand-held Quantum Flux meter Model MQ-500. The experiment was carried out in a commercial Krissy seedless vineyard that utilized east-west row orientation. The vineyard was treated by best common practices, including leafing and centering (i.e. shoot pruning along the alleyway) for light penetration.

[0120] The experiment utilized 5 different conditions: a control that did not feature the panels described herein, treatments that utilized fully-holey polymer pearl, orange, and red panels described herein, and a treatment that used a partially-holey polymer pearl panel with a rain- protection strip (referred to as“Pearl+”). Each experimental condition covered a gable-to-gable section (4 vines). Panel sections and control sections were separated by buffer sections. The experimental layout was arranged in 8 fully randomized repetition blocks.

[0121] Light readings were collected from 15 different locations for each condition and each repetition on the north side of the vines at 165 cm height above ground level, just above the fruiting zone (which spans between 110 cm andl60 cm above ground level). The sensor was held horizontally facing south. The intensities were recorded as average photosynthetically active radiation (PAR) values in units of pmol photons*m ² *s ¹ . The standard error was calculated from the 8 averaged values for each condition.

[0122] FIG. 15 illustrates the results of different colored panels on light intensity in vine inner canopies near fruiting zones. The panels described herein clearly increase the light intensities by more than 100% in all cases.
