| 摘 要： | 银合欢为豆科含羞草亚科银合欢属木本植物,现发现22个种,其中18个种为二倍体,4个种为四倍体。银合欢栽培种可作于薪材、木料、造纸、木炭、遮荫和绿肥等,已在澳大利亚、印度、巴拉圭、泰国、中国和其它东南亚国家种植。综述了银合欢的种质收集、评价及分类学研究,分子遗传学研究,种间杂交,增加遗传多样性,抗异木虱育种,耐寒、耐霜和耐旱育种,高产优质牧草育种,优质高产木材育种,不结籽树种育种等。

| Abstract: | The genus Leucaena(sub-family Mimosoideae,family Leguminoseae)comprises 22 recognized species,of which 18 are diploid and four are tetraploid.Many hybrids are sterile triploid.Leucaena cultivars are planted for fuelwood,lumber,paper,charcoal,shade and green manure.The expanded production of the unproved cultivars is notable in Australia and in India,Paraguay,Thailand,and South East Asia.Leucaena reseach including taxonomy,germplasm,interspecific hybridization,increasing genetic diversity,breeding fro psylli... |
