The Influence of Low Phosphorus Stress on the Yield of Shennong 265 and Liaojin 294

Grain yield and biomass decrease with low phosphate in field,and reduce of Shennong 265 by a small margin.Spike and grain number of Shennong 265 also decrease with Low phosphate in field,grain density per spike reduce;while spike longth increase,grain number and grain density per spike of Liaojing 294 is upping with low phosphate in field,the difference perhaps due to low phosphate in field made the tiller number of Liaojing 294 decrease more.The comprehensive low-phosphate-bearing ability of Shennong 265 reach to the first level,and that of Liaojing 294 reach to the second level.Which indicates Shennong 265's low-phosphate-bearing ability is very great,and Liaojing 294's is middle.
