In order to improve spikelet fertility and grain weight of inferior spikelets in super rice, 3.2%GA3·PP333 (Lilibao,LLB) were sprayed on super rice Yongyou 12 three days after heading. We investigated the effect of LLB on grain yield and the underlying mechanisms. The results indicated that LLB increased the grain yield by 4.41% and 4.31% in 2012 and 2013, respectively compared to corresponding controls, while the theoretical yield showed 9.21% and 6.26% increment. This may be ascribed to increased seed-setting rate and grain weight under LLB treatment compared with the control. It had been observed that there was no significant difference in pollen viability and pollen numbers on stigma between the LLB treatment and control, while the LLB treatment significantly increased the pollen germination on stigma, which was responsible for the improvement in seed-setting rate. Additionally, the chlorophyll content, net photosynthetic rate and specific leaf weight of flag leaf in the LLB treatment were higher, while the ratios of soluble sugar content in leaf to grain were lower than those of the control in the late grain filling period, indicating that LLB could not only delay the leaf senescence but also promote transportation of assimilates to grains.
Key words： 3.2%GA3·PP333; super rice; grain yield; spikelet fertility; 1000-grain weight
