متن کاملAbscission: role of cellulase.
Cellulase (beta-1,4-glucan-glucanohydrolase EC 3.2.1.4) activity increased during abscission and was localized in the cell separation layer of Phaseolus vulgaris L. cv. Red Kidney (bean), Gossypium hirsutum L. cv. Acala 4-42 (Cotton) and Coleus blumei Benth. Princeton strain (Coleus) abscission zone explants. Cellulase activity was optimum at pH 7, was reduced by one-half after heating to 55 de...
متن کاملPistillate Flower Abscission - 1990
Evaluation of the pistillate flower abscission (PFA) potential of UC-67-13 and UC-67-11 was continued at two sites. At a high PFA site UC-67-13 PFA was only moderately lower than Serr for the third year. UC-67-11 demonstrated low PFA potential for a seconq year at this site. Higher PFA potential of UC-67-13 than UC-67 -11 was also found at a second site for a second year. No further evaluation ...
متن کاملPistillate Flower Abscission (pfa)
PFA was not different with shaded vs. exposed limbs of the same trees nor between shaded interior trees and outside ones with high light exposure. Tehama trees expressed lower PFA than adjacent Serre PFA of Tehama was also low at a site where Serr trees (removed 1982) had very high drop the previous three years. Fruitfulness of all monitored limbs in 1982 ranged from 6 to 97% and the earlier co...
متن کاملAdvances in abscission signaling.
Abscission is a process in plants for shedding unwanted organs such as leaves, flowers, fruits, or floral organs. Shedding of leaves in the fall is the most visually obvious display of abscission in nature. The very shape plants take is forged by the processes of growth and abscission. Mankind manipulates abscission in modern agriculture to do things such as prevent pre-harvest fruit drop prior...
