1.銀坊水稻大概在25℃-30℃的溫度下較爲適當的通過春化階段,春化7天比較合適,生長點分化程度比較快。2.自播種到抽穗期間給以連續短日處理對抽穗促進程度最顯著,能提早45天。3.晚熟粳稻對短日照要求比對溫度的要求更爲嚴格。如銀坊稻在短日照條件下無論經過春化處理或未經春化處理的植株,抽穗期均比自然對照提早45天左右。而不同春化處理間植株的抽穗期差异不大。4.銀坊稻光照階段發育進行的速度與植株營養體生長情況成正相關。例如24小時長光照培育214天,生長點未分化的植株,放在8小時短光照下處理14天,生長點已分化出第一次枝梗始原體,且分化出白毛,而播種後即以8小時短光照處理的幼苗,雖經30天生長點尚無分化的傾向。5.銀坊稻光照階段質變可能是在第一次枝梗始原體形成以前完成的。
1. Yinfang rice probably passes through the vernalization stage at about 25 ℃ -30 ℃, and vernalization is more suitable for 7 days. The differentiation of growth point is faster. 2. From shortening to sowing, continuous short-day treatment has the most significant effect on heading, which can reach 45 days earlier. 3. Late maturing japonica rice requirements for short-term temperature requirements more stringent than. For example, if the plants were treated with vernalization or vernalization in short-day conditions, the heading date was about 45 days earlier than that of natural control. However, there was no significant difference in the heading date between different vernalization treatments. 4. The speed of the development of Yinfang rice stage was positively correlated with the vegetative growth of plant. For example, a 24-hour long light was grown for 214 days. Undifferentiated plants were grown for 8 days in short light for 14 days. The growing point had differentiated into first prickly stem and differentiated white hair, Seedlings treated with 8-hour short-light had no tendency to differentiate even after 30 days of growth. 5. Silver Square rice stage light quality changes may be formed in the first branch of the primitive body to complete.
