Title:
LEAF IN-SITU DARK ADAPTATION DEVICE AND METHOD FOR CHLOROPHYLL FLUORESCENCE MONITORING
Document Type and Number:
WIPO Patent Application WO/2023/179354
Kind Code:
A1
Abstract:
Disclosed are a leaf in-situ dark adaptation device and method for chlorophyll fluorescence monitoring. The device comprises an outer box and an inner box; ventilation holes arranged alternately are formed in the peripheries of the outer box and the inner box of the device; push-pull movable doors are designed on two sides of the outer box; a round hole allowing plant leaf stems to pass through is formed in the center of each door; the bottom of the outer box is connected to the inner box by means of an air exchange cylinder; an air exhaust fan is arranged in the air exchange cylinder; air enters the inner box from the air holes in the periphery of the outer box and is pumped out from the fan to form air circulation in the device. The inner box is also provided with detachable push-pull doors, a temperature module, and a humidity module, and the height and angle of a support are configured to adjust the position of the device so as adapt to growth angles of plant leaves. Inner and outer box sliding doors of the device are connected by means of grooves therein so as to facilitate assembly and disassembly. Leaves can be conveniently placed in and taken out without damaging the normal life activity of a plant, and it is easy to disassemble and clean. According to the device, in-situ dark treatment can be carried out on plant leaves of any heights and angles, and leaf chlorophyll fluorescence parameters can be conveniently obtained in situ.
