摘要
对若干核果类果树苗木生长势与电阻率关系的研究表明 ,参试各种内的实生苗生长势与其主干电阻率呈显著 (α =0 .0 5 )或极显著 (α =0 .0 1)正相关 ;以普通杏、西伯利亚杏、碧桃、毛桃为砧木的杏嫁接苗生长势与其主干电阻率呈显著或极显著正相关 ;以普通杏、西伯利亚杏为砧木的杏嫁接苗与砧木的主干电阻率呈显著或极显著正相关。
The studis on the relationship between electric resi stivity and the heigh of some drupaceous seedlings showed that: the height of at tended species-seedling was significant(α=0.05)or highly significant(α=0.0 1) positive correlation with electric resistivity of trunk; When duplex persica (Amygdalus persica var. duplex Sieb. et Zucc.) or persica (A.persica Sieb. et Zucc.) or apricot (Armeni aca vulgaris Lam.) or sibirica apricot (A.sibirica L.) as apricot rootst ock, the height of grafted seedling was significant or highly significant positi ve correlation with its electric resisticity of grafted seedling; The height of grafted seedling on apricot or sibirica apricot was significant or highly signi ficant positive correlation with trunk electric resisticity of stock-seedlings.
