外源ABA、ZR及IAA对甘薯脱毒苗生长及结薯的影响
Effects of Exogenous ABA,ZR and IAA on Growth and Tuber Setting of Virus-free Sweet Potato Seedlings
摘要
Abstract
The virus-free test tube seedlings of sweet potato variety'Longshu No.9'were cultured in pot medium,and plant hormones were added to the root nutrient solution.The influence of 0(CK),0.7,7 and 14 mg/L ABA,and IAA and 0(CK),0.8,8 and 16 mg/L ZR on the growth and tuber setting of virus-free sweet potato seedlings by a single factor experiment.The results showed that the number of potatoes and potato weight of 0.8 mg/L ZR treatment increased by 2.25 and 5.93 g compared with CK,and the number of potatoes and potato weight of 0.7 mg/L ABA treatment increased by 2.00 and 5.43 g.The 14 mg/L IAA treatment could significantly increase the length of root and stem.In conclusion,during the production of virus-free potato,0.7 mg/L ABA or 0.8 mg/L ZR applied to the root can significantly increase the number of nodules and weight of the potato,and the addition of 14 mg/L IAA to the root can promote the elongation of the root and stem of the seedlings.The result can provide technical support for the efficient production of virus-free seed potato seedlings.关键词
