通过多年田间调查、试验处理及分析测定,结果显示库尔勒香梨没有代表果形,一般在近圆形、广卵形、椭圆形和纺锤形范围内变化,果形外观虽有不同,但品质风味无明显差异,突顶果不是生理病害现象。花期是决定果形变化的主要时期,树体幼果内源激素的分配差异可能是导致不同果形的决定因素。在花期喷施相关生长调节剂可以人工诱导果形变化趋向,减少甚至消除突顶果的发生。
Through many years of field investigation, experimental treatment and analysis, the results showed that Korla fragrant pear did not represent the fruit shape, generally in the near-circular, broad oval, oval and spindle-shaped range, fruit appearance although different, but the quality of flavor No significant difference, Dingjue fruit is not a physiological disease phenomenon. Flowering is the main period that determines the change of fruit shape. The difference of endogenous hormones distribution in juvenile fruit may be the determinant of different fruit shapes. Spraying related growth regulators at flowering stage can artificially induce the trend of fruit shape changes, reducing or even eliminating the occurrence of condoms.
