胡萝卜肉质根大小对种株发育及采种的影响

Effect of the Fleshy Root Size on the Plants Development and Seed Collecting of the Carrot

针对目前我国胡萝卜采种生产中留种肉质根大小无标准的问题,以甜红1号胡萝卜杂交新品种之亲本为供试材料,通过设定不同的肉质根大小,进行植株生长发育形态与种子产量等相关指标的测定,以探讨胡萝卜肉质根大小对种株发育及产量的影响。结果表明,大根种株胡萝卜的各项形态指标均比中根和小根种株要高,其种子产量显著高于中根种株,极显著高于小根种株;在发芽率方面,大根种株也优于中根和小根种株。

In view of the problem of non-standard size of carrot fleshy root in our country at present, this study was designed the new varieties of Sweet Red 1 carrot hybrid parents as the tested materials, by setting different root size, determining the plant growth morphology and seed yield and other related indicators, to investigate the effect of root size on plants development and seed collecting of carrots. The results showed that the big root carrot was higher than the medium and the small root on the morphological index, and the seed yield was significantly higher than that of the medium root, was extremely significantly higher than that of the small root; and on the germination rate, the big root was better than that of the medium and the small root.
