Taking a medium season japonica variety Wuyujing 3 and a medium season hybrid rice Shanyou 63 as experimental materials, the populations with different percentages of panicle bearing tillers and stems were formed by different planting density and N fertilizer applying treatment. The relationship between source quality at heading stage and its influencing factors were studied.For rice population with high grain yield, at heading stage, LAI was appropriate, rate of effective leaf area was high, rate of...

Taking a medium season japonica variety Wuyujing 3 and a medium season hybrid rice Shanyou 63 as experimental materials, the populations with different percentages of panicle bearing tillers and stems were formed by different planting density and N fertilizer applying treatment. The relationship between source quality at heading stage and its influencing factors were studied.For rice population with high grain yield, at heading stage, LAI was appropriate, rate of effective leaf area was high, rate of highly effective leaf area is from 75% to 78%. And during filling period, photosynthetic potential is higher than 2.10×10 6 m 2·d,photosynthetic potential\|grain ratio was higher than 47 cm 2·d/spikelet. Photosynthetic potential\|grain ratio(ratio of photosynthetic potential after heading versus the total quantity of spikelets) reflected the developing relationship dynamically of source\|sink after heading, it is a better indication for source and sink quality during period of economic yield formation. Under conditions of these experiments, applying panicle fertilizer and so on based on the appropriate leaf area at heading stage would be effective measures for reducing the declining rate of leaf area, increasing the photosynthetic potential and photosynthetic potential grain ratio, and obtaining further higher grain yield.

We studied the relationship between source quality at heading stage and it′s influencing factors, the results were as following: For rice population with high grain yield, at heading stage, LAI was appropriate, ratio of effective leaf area was high, ratio of highly effective leaf area is 75%~78%. And during filling period, photosynthetic potential is higher than 2.1×10 6 m 2·d -1 , photosynthetic potential\|grain ratio was higher than 47 cm 2·d -1 spikelet. Photosynthetic potential\|grain ratio (ratio of photosynthetic potential after heading versus the total quantity of spikelets) reflected the developing relationship dynamically of source\|sink after heading, it′s a better indication for source and sink quality during period of economic yield formation. On the base of appropriate leaf area at heading stage, which would be effective measures for further higher grain yield that reducing the declining rate of leaf area, increasing photosynthetic potential\|grain ratio.
