摘　　要：以8、9年生中华猕猴桃为试材,定期测量了果实的纵径、宽横径和厚横径及其日生长量,观察其果实生长发育变化规律。结果表明：在贵州地区中华猕猴桃结果蔓上结果节位的果实纵横径生长量在年生长过程中有2～5次生长高峰期,其中,纵径有3～5次生长高峰,上芽、二芽、三芽、四芽和五芽分别为4、4、3、4、5次;宽横径有3～4次生长高峰,上芽、二芽、三芽、四芽和五芽分别为4、4、4、3、4次;厚横径有2～5次,上芽、二芽、三芽、四芽和五芽分别为4、4、2、3、5次。中华猕猴桃结果蔓上结果节位的果实纵横径日生长量在年生长过程中有4～6次生长高峰期,其中,纵径有4～5次生长高峰期,上芽、二芽、三芽、四芽和五芽分别为5、4、4、4、4次;宽横径有4～6次,上芽、二芽、三芽、四芽和五芽分别为5、5、5、4、6次;厚横径有5～6次,上芽、二芽、三芽、四芽和五芽分别为5、5、5、6、6次。由此可见,猕猴桃结果蔓上结果节位直接影响了果实纵、横径的生长高峰次数、高峰出现的时间和生长曲线的起伏程度,也影响了果实的单果重和质量,因而必然影响果实的成熟时间。Taking 8～9 year-old Chinese kiwifruit as materials,longitudinal diameter,wide diameter and thickness transverse diameter and their day growth were regularly measured,the fruit growth dynamic were observed.The results showed that,under the condition of the Guizhou region,there were 2～5 times the growth peak on the kiwi fruit vertical and horizontal diameter increment in the growth process,among which,longitudinal diameter had 3～5 times growth peak,the top bud,second bud,third bud,fourth bud and fifth bud were 4,4,3,4 and 5 times respectively;Wide diameter had 3～4 times growth peak,the top bud,second bud,third bud,fourth bud and fifth bud were 4,4,4,3 and 4 times respectively;thick diameter had 2～5 times growth peak,the top bud,second bud,third bud,fourth bud and fifth bud were 4,4,2,3 and 5 times respectively.The fruits of the kiwi fruit day growth on a vertical and horizontal diameter increment in the growth process had 4～6 times growth peak,day growth longitudinal diameter 4～5 times,the top bud,second bud,third bud,fourth bud and fifth bud were 5,4,4,4 and 4 times respectively;day growth width diameter had 4～6 times,the top bud,second bud,third bud,fourth bud and fifth bud were 5,5,5,4 and 6 times respectively;Day growth thick diameter had 5～6 times growth peak,the top bud,second bud,third bud,fourth bud and fifth bud were 5,5,5,6 and 6 times respectively.The kiwi fruit section on tendrils impacted longitudinal and transverse diameter of fruit growth peak,peak appearing time and growth curve,also affected the weight of the fruit yield and quality,and was bound to affect the fruit ripening time.
