studies were made on the vegetative propagation coefficient and cormels biological characters using eighth-excision in different development phase of lycoris radiate.
在红花石蒜不同生长发育期进行八分法切割繁殖,研究无性繁殖系数和子球生物学性状差异性。
seedling grew fast in orchard, having strong resistance, but the low survival rate of field cutting, propagation coefficient is not high, limiting the speed of its promotion.
建立园圃其实生苗生长迅速,抗逆性强,但大田扦插育苗成活率低,繁殖系数不高,限制了其推广速度。
the affinity of self-incompatibility in the mustard family affects the purity of hybrid seed and the propagation coefficient of stock plant.
