在密封或通气条件下,研究了培养基中加入适量硝酸银对马铃薯品种东农303和兰芽试管苗与试管薯的影响.结果表明,硝酸银处理后苗高下降,而试管苗的根长和叶面积显著增加.叶面积在封闭和通气条件下分别增加了5倍和3倍.通气条件下生长的试管苗,茎叶失水率比密封条件下显著减少,而苗长和叶面积有一定程度的增加.马铃薯品种东农303和兰芽分别在7.5和2.5 mg?L-1浓度硝酸银处理下,试管薯鲜重和大薯百分率显著提高.
Under sealed or aerated conditions, the effect of adding proper amounts of silver nitrate on the growth of potato cultivar Dongnong 303 and Lanyou germplasm and tube were studied.The results showed that the seedling height decreased after treated with silver nitrate, while the root length And leaf area increased significantly.The leaf area increased by 5 times and 3 times respectively under the condition of closed and aeration.The water loss rate of tube plantlets and stems and leaves grown under aeration condition was significantly lower than that under sealed condition.The seedling length and leaf area had Increased to a certain extent.The fresh weight and the percentage of big potato of potato cultivar Dongnong 303 and Lanya were significantly increased under 7.5 and 2.5 mg? L-1 concentrations of silver nitrate treatment respectively.
