枝条电阻率与苹果砧木矮化效应的关系
RELATIONS BETWEEN SHOOT’S RESISTIVITY AND EFFECT OF APPLES STOCK DWARF
【摘要】 本文提供了一种苹果枝条电阻率的测定方法。运用该法测定矮化砧M9,半矮化砧M26、M7,半乔化砧M106,乔化砧山定子的结果表明,果树砧木的矮化效应直接与枝条电阻率相关,以枝条电阻率作为矮化砧木预选指标,可以不受被测枝条粗细必需一致的限制。
【Abstract】 A method of estimating apples shoot’s resistivity has been put forward in this paper. The method is applied in dwarf stock M., semi-dwarf stock M26 and M7, semi-vigorous stock M106 and vigorous stock M baccate borkin. Experimental results show that the effect of apples stock dwarf has directly something to do with the shoot’s resistivity, and pre-selection of dwarf stock is not limited by the same shoot’s diameter if shoot’s resistivity is considered pre-selection index of dwarf stock.
