摘要
在特种稻黑宝3号的初花期喷施0.005～0.020 mg/L油菜素内酯(BR),剑叶中的叶绿素、可溶性糖、淀粉含量提高,光合速率增强,灌浆速率增大,结实率和千粒重增加,比对照增产10.18%～12.85%,对黑糙米中花青苷含量无影响。
BR （0.005-0.020 mg/L） was sprayed on special rice variety Helbao No.3 during early blooming stage. Chlorophyll, dissoluble sugar and starch content in flag leaves increased. And photosynthesis rate, filling rate, seed setting rate and thousand grain weight enhanced. The yield increased by 10.18 %-12.85 % compared with that of control group. This method had no affect on the anthocyanin content in black unpolished rice.
