‘美登’蓝莓对高pH值适应性的驯化提高试验

Domesticated Lncrease Blomidon to High pH Adaptability Test

为提高‘美登’蓝莓对高pH值的适应性,以期达到我国大部分地区种植‘美登’蓝莓不需要改土或减少改土成本的目标。以高寒地区蓝莓栽培首选品种‘美登’的无根组培苗为试材,采用pH梯度(5.0、5.2、5.4、5.6、5.8、6.0、6.2、6.4、6.6)驯化培养的方法使其逐步适应高pH值。结果表明,经过梯度驯化培养的‘美登’蓝莓在pH为6.6的培养基中的分化数为7.9±1.0,明显多于不经过梯度驯化的1.8±0.8;分化出的丛生芽的生长状况(茎高、茎粗及叶色)也明显优于不经过梯度驯化的。经pH梯度驯化培养可以提高‘美登’蓝莓对高pH值的适应性。

Domesticated increase Blomidon to high pH adaptability, in order to grow Blomidon in most regions, don＇t need improve the soil or reduce the cost. Blueberry cultivation in cold area preferred varieties Blomidon, no root somaelone as test materials, the pH gradient （5.0, 5.2, 5.4, 5.6, 5.8, 6.0, 6.2, 6.4, 6.6）, the method of inoculating culture gradually adapt to the high pH value. Results, After gradient domestication cultivation of Blomidon in the culture medium of pH 6.6 differentiation number isT. 9± 1.0, significantly more than without gradient domestication of 1.8±0.8; Differentiation from the bud of growth, stem height, stem diameter and leaf color are better than those without gradient domestication. The pH gradient domestication training can improve the Blomidon adaptability to high pH value.
