摘要
雾培法生产马铃薯脱毒微型薯是一项新型的无土栽培技术。甘肃省马铃薯微型薯雾培法生产中存在品种数量较少、多样性程度较低的问题,阻碍当地马铃薯产业化发展。为筛选出适宜雾培法生产微型薯的马铃薯新品种,促进甘肃省马铃薯产业的发展,选用4个马铃薯品种,以当地雾培主栽品种‘庄薯3号’为对照,采用马铃薯微型薯雾培法进行品种比较试验,对不同马铃薯品种的形态指标、生理指标及微型薯产量进行比较研究。结果表明,不同品种在株高、茎粗、根长、叶面积、叶绿素SPAD值、匍匐茎数量和微型薯产量方面存在差异。从单株结薯数来看,‘庄薯3号’(CK)微型薯产量最高,‘庄薯4号’和‘天薯11号’次之,‘陇薯10号’和‘冀张薯8号’产量最低。通过比较研究,‘庄薯4号’和‘天薯11号’品种生长性状好、微型薯产量高,适合雾培繁育微型薯。
Potato minituber production in aeroponics is a new soilless cultivation technique.Few varieties and less diversity of potato varieties make it hard to develop potato industry in Gansu Province.In order to select potato varieties suitable for the production of minitubers in aeroponics,and thereby promote development of potato industry in Gansu Province,four potato varieties were introduced and compared with the control variety'Zhuangshu 3'for their morphological indexes,physiological indexes and minituber yields.There were significant difference in plant height,stem diameter,root length,leaf area,leaf SPAD value,stolon number,and minituber yields of different potato varieties.The potato variety'Zhuangshu 3'produced the highest minituber number per plant,followed by'Zhuangshu 4'and'Tianshu 11',and'Jizhangshu 8'and'Longshu 10'had the least minituber number.After comprehensive comparison,'Zhuangshu 4'and'Tianshu 11'showed good growth and high yield characteristics,which were suitable for minituber production in aeroponics.
