摘　　要：1987年和1988年以染色体倍数不同的-15个小麦种为材料,研究不同染色体组成对诱导愈伤组织和分化绿苗的效应。结果表明,愈伤组织的诱导率分别为41.1％(二倍体小麦),76.6％(四倍体小麦),81.3％(六倍体小麦).六倍体小麦最高,绿苗分化率也有类似趋势。染色体倍数相同的不同小麦种,其诱导率和绿苗分化率差异显著。在6个六倍体小麦种间,斯卑尔脱小麦的绿苗分化率仅为14.3％,而云南小麦的绿苗分化率可达57.5％(1988)。根据二年试验结果,初步肯定了云南小麦在6个六倍体小麦种中绿苗分化率表现最高。This study dealt with the effects of chromosome complement on callus induction and differentiation in 15 Triticum species of different Pl-oidy in 1987-1988. The results showed : 1, The rate of callus induction was highest in hexaploids (averaging 81.3%) , followed by tetraploids (76.6%) and diploids(41.1%).The rate of plant regeneration had the same trend. 2, The rates of callus induction and differentiation differed significantly among different species of the same ploidy. In the 6 hexa-ploid species, the rate of plant regeneration in Tr. spelta was onlyl4.3% while in Tr. aestivum ssp yumnenese it was as high as 57.5%.
