e0“the total spike number per plant of Jimai 22 and Shannong 23 were 0.36 and 0.41 higher than no irrigation in two years.”
t0“wheat”
t1“the total stem number per plant of Jimai 22 and Shannong 23 under W70 were 1.01 and 0.75 higher at wintering stage and 0.71 and 0.56 higher at jointing stage. The photosynthetic parameter of the uppermost unfolding leaves at jointing stage, dry matter weight and distribution amount of 13C assimilates of main stem and tillers in different positions increased significantly, the total spike number per plant of Jimai 22 and Shannong 23 were 0.36 and 0.41 higher than no irrigation in two years. The grain yield of Jimai 22 and Shannong 23 under water-saving irrigation treatment increased by 35.00% and 44.27%, and water use efficiency increased by 9.23% and 8.55% than no irrigation, respectively. Further increasing the amount of irrigation to sufficient irrigation treatment could increase the total stem number per plant at wintering and jointing stage, but there was no significant difference with water-saving irrigation in the total formation spike number per plant, spike number, and grain yield per hectare, water use efficiency was decreased. Comparison among the cultivars the total stem and spike number per plant of Jimai 22 were higher than Shannong 23, the main reason was that Jimai 22 had higher tiller node area and trans zeatin content, photosynthetic capacity in main stem, and tillers in different positions. The correlation analysis showed that the total stem number and spike number per plant, spike number, and grain yield per hectare were positively correlated with the tiller node area and trans zeatin content, and net photosynthetic rate of the uppermost unfolding leaves in main stem in two wheat cultivars”
