摘要:
为满足人们对经过热处理的美国紫薯试管苗种苗的大量需求，以微型嫩茎段为材料，采用组织培养和微型扦插的方法，进行了试管苗微型繁殖的研究。结果表明：在1/2MS+IAA0.2 mg?L-1+蔗糖15 g.L-1培养基上，以具有2个生长点和2个叶片的微型茎段繁殖试管苗，1株试管苗每年能繁殖200多万株试管苗；以具有2个生长点和2个叶片的苗微型茎段扦插到苗床上，其繁殖速度提高了1.8倍。定植的微型扦插试管苗生长较旺盛，美国紫薯的产量提高48.9%。
Abstract:
In order to meet the large needs for tube seedlings of Ipomoea batatas after heat treatment,with the method of tissue culture and micro cutting,the mini tender stem segments were used as material to do the research on micro propagation of tube seedlings in vitro.The results demonstrated that in the media of 1/2MS+IAA 0.2 mg?L-1-+Sucrose 15 g?L-1-,one tube seedling,which reproduced by mini tender stem segments with 2 growing points and 2 blades in vitro,could breed more than two million tube seedlings each year;with 2 points and 2 blades of micro cuttings to the seedbed propagation speed was increased by 1.8 times.Colonization of the micro cutting plantlets grew strongly,the yield of Ipomoea batatas could increase by 48.9%.
