摘要
为提高苜蓿单一性状,加速苜蓿的良种繁殖,针对苜蓿在高寒高海拔地区种植难、返青缓慢的特点, 用不同浓度的萘乙酸处理苜蓿插条,进行了无性繁殖的探索和研究。试验结果表明:萘乙酸处理苜蓿插条的最适浓度是4 g萘乙酸/5kg水,其苜蓿插条成活率达到81．7％,返青率达86．7％。
In order to improve the alfalfa oneness character and accelerate the good kind of alfalfa breeding. Aim at the difficulty of planting alfalfa in the high and cold region, and characteristics of returning green slow, the asexual reproduction was studied. Through treating alfalfa quickset with NAA Acetic Acid of different concentration, the results showed the treatment of every 5kg water contain 4g NAA acetic acid was the best Concentration, the survival ratio was 81.7%, and the returning green ratio was 86.7%.
