【摘要】 以耐缺磷系数为指标研究了黑龙江省 32个春小麦品种 (系 )对磷素的敏感性。研究指出 ,成熟期株高、穗长、小穗数和穗粒数的耐缺磷系数都可以做为高效利用磷素基因型的筛选指标 ;并初步筛选出了 5个高效利用磷素的基因型更多还原

【Abstract】 Spring wheat varieties or breeding lines grown in Heilongjiang province were employed to study their sensitivity to phosphorus with the index of phosphorus-shortage tolerance(IPST). The results indicate that the IPST of plant height,spike length,spikelet number and grain number per spike at mature stage could be used as parameters of screening wheat genotypes for high-efficiency utilization of phosphorus. As a preliminary result,5 wheat genotypes for high-efficiency utilization of phosphorus were singled out.更多还原
