摘 要: | 1981年以来,我们开展了野生稻资源繁殖特性和繁种技术的研究,结果表明:稻属不同群的野生种,其繁殖特性有较大差异,光周期敏感性,以 sativa 群最强,officinalis 群范围较宽,混杂群的云南疣粒野生稻不感光。小穗育性从高可育到高不育。南宁是适宜于野生稻繁种的地点之一。始穗期用孔径小的尼龙丝网袋,套袋并插竹杆作支架的繁种方法,对提高野生稻繁种收种产量作用显著,可以推广利用。

STUDY ON THE REPRODUCTION TECHNIQUES OF WILD RICE RESOURCES |

Abstract: | Since 1981,the reproductive characteristics and the production techniques of wild rice resources have been researched.The results showed that there were much differences in productive characteristics among different groups of wild rice.In photoperiodical sensibility,the group Sativa is very strong,the group Oficinalis is little,the mixed group is nophotosenitive.Nanling is one of the suitable place for reproducing wild rice.A new reproduction method which can clearly raise the seeds yield was put out.In this paper,that is to put rice ears into a nylon bag with small holes and sustain it by a stick during the ears of wild rice were out. |
