食用型向日葵品质育种

EFFECT OF PP333 ON GROWTH OF STEM, LEAF AND ROOT OF SOYBEAN WITH WATER CULTURE

摘要:

食用型向日葵在整个向日葵生产中占有很大的比重。其品质育种目标与油用型向日葵有所不同，在中国食用型向日葵有二种主要用途，一是作为动物饲料的蛋白质来源，主要是脱脂后的向日葵饼粕，二是人们日常的干果食品，这与向日葵瘦果的性状有直接关系。本文对世界范围内食用型向日葵的最新研究成果，特别是与品质相关的性状遗传规律给予介绍并对主要的育种方法及其存在的问题进行综合评价，特别是对半分法给予较为详细的描述。笔者认为在目前情况下，根据中国的实际情况半分法可作为选育食用型向日葵的一种有效的育种和提纯复壮方法给以推广。

Abstract:

Effect of PP333 on growth of stem,leaf and root of soybean young plant with water culture was studied.The experimental results showed that PP333 decreased not only length of stems and roots,but area of leaves. The inhibition was increased with increasing treatment concentration of PP333.Growth of root system was seriously inhibited by soaking roots with PP333 solution.
