摘要
本文对青海春萝卜主栽品种的种皮进行细胞组织结构观察和发芽率的测定 :可知萝卜种皮结构有 4个组分 ,即表皮、厚壁组织、内珠被遗迹及色素层 ;萝卜种子发芽率的高低主要与厚壁组织层的厚度及它占种皮全厚的比例有关 ,且成反比。
In this paper,auatomic examinations were made on seed coats of 3 varieties of spring Raphanus sativus in Qinghai,and germination percentages were measured.Conclusions were drawn:thickness of sclerenchyma correlates with gemination percentage,and was in inverse proportion to gemination percentage.
