摘要
为了充分了解甜叶菊的生态适应性,为甘肃甜叶菊生产基地建设提供理论支持,从江苏、河北、安徽等地引进7个甜叶菊品种进行引种鉴定试验,通过对参试材料的生长特性、产量和甜叶菊糖苷含量分析,结果表明:甜叶菊具有较强的适应性,在西北地区可以广泛种植;引进的ZS-2干叶产量和茎秆产量都最高,达4801.50 kg/hm2和5647.33 kg/hm2;ZS-1的莱苞迪苷A和总苷含量都高,分别为7.69%、12.39%,达极显著水平。综合分析得出,ZS-1甜叶菊糖苷产量最高,可以作为主栽品种在河西推广栽培,ZS-2也具有一定的推广价值。
Seven Stevia rebaudiana ecotypes were introduced from Jiangsu, Hebei, Anhui regions and cultivated for comparative experiment in Gansu. The result showed that S. rebaudiana had stronger ecological adaptability and widely planted in the northwest of China; Both dry leaves yield and stalk yield of ecotype ZS-2 were the highest, reached 4801.50 kg/ha and 5647.33 kg/ha, and the rebaudioside A and stevioside content of ZS-1 were the highest, reached to 7.69% and 12.39%. Comprehensive analysis indicated that stevioside yield of ZS-1 was the highest as advantage ecotype for extend culture Hexi area.
