- 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。
- Abstract:
- 32 Spring w heat varieties or breeding lines grown in Heilo ngjiang province were employed tostudy their sensitivity to phosphorus with the index of phosphorus -shortage tolerance(IPST).Theresults indicate that the IPST of plant height , spike length , spikelet number and grain number per spikeat mature stage could be used as parameters of screening w heat geno types for high -efficiency utilization of phosphorus .As a preliminary result , 5 w heat genotypes for hig h -eff iciency utilization of phosphorusw ere singled out
