| 摘 要： | 在人工气候室中,研究了7个不同类型水稻品种(系)的抽穗期对16h 长光照和10h 短光照的反应特性.结果表明:(1)不论是早稻还是晚稻,籼稻还是粳稻,均存在明显的“长日促进期”,把水稻基本营养生长期分为长日亚期(BVP—Ⅰ)和短日亚期(BVP—Ⅱ)是合理的;(2)长日照对不同品种有不同程度的抽穗阻滞效应;(3)强感光的晚稻品种未观察到长日补偿期,在连续16h 长光照下未能进入幼穗分化.

| Abstract: | The response of different rice varieties(lines)to 16-hour long day and 10-hour short day was studied in phytotron.The results indicated that:(1)there existed the phase of“long day acceleration phase(LAP)” in all-types of rice,including early-and late-maturing,O.sativa indica and O.sativa japonica,so it would de reseanable that basic vegetative period (BVP)be derided into two subphase,BVP-Ⅰ(long day subp.)and BVP-Ⅱ (short day subp.∫.(2)there were different long-day inhibitory effect on the heading in various rice varieties;(3)no“long day compensation phase” (LCP)was observed in strong photo-sensitive late maturing varieties,they could not initiate under the condition of continous long-day treatment. |
