| 摘 要： | 通过对辽宁省杂草稻的分蘖、株高、有效穗数、穗长、穗粒数、千粒重、抽穗期、抽穗时壳色、叶毛、1～2穗节长、籽粒长宽比、酚反应、稃毛、芒、颖壳色15个生物学性状的调查。结果发现,杂草稻前期具有明显分蘖优势,株高大部分高于对照栽培稻,颖壳色从黑灰色到稻草色,芒色从紫色到黄色,芒长从0～69 mm等方面具有几乎连续变化的多态性。

| Abstract: | In order to study biological characteristics of weedy rice, effects of water regime and herbicides on its emergence and growth were studied. Total of 92 accessions of weedy rice from 19 districts in Liaoning province were analyzed in 15 biological traits. With those data, higher initial tillering velocity and stem length were found in weedy rice compared with the cuhivars. The color of grains was from dark gray to straw-like; the color of awn was from purple to yellow and the length of awn was from 0-6.9 cm. |
