| 摘 要： | 对陕西关中地区小麦品种发育特性的研究表明，随着品种更换虽然进入幼穗伸长的时间缩短，但品种未出现春性化，开花期在品种间差异不大，但二棱期至开花期的时间缩短，这是感光性减弱的结果；由于伸长期至二棱期的时间延长，从而利于增花增粒，近期育成的大穗品种多有明显的春性化，强感光性，需要加以改进。

| Abstract: | The development characteristics of wheat cultivars grown in Mid-Shaanxi area were studied.The results indicated that therewas not tendency changing from winter type to spring type during thewheat cultivars substitution, though the tine of spike development trended to early.The anthesis did almost not change and the tine from double ridge to anthesis shorted, whichwas result of weakening photoperiodign.Extending the tine from initial elongation to double ridge of the apical cones was contribution to foam big spike But there were obvious spring and strong photoperiodign tendencies among present big spike cultivars.These need to improvement. |
