Abstract:By using block design the effect of 6-benzyladenine, 6-Amine and zeatin spray on senescence prevention and yield of pellicle dry-cultivated rice during its early earning stage were studied. The results showed as follows: the early-senescence was effectively prevented and the yield was significantly increased when 6-BA used on pellicle dry-cultivated rice, the highest yield increased reached 15.94%. At the same time, the effect of 6-Amine and zeatin were not significantly.
