摘　　要：以7年生萨米脱甜樱桃为试材,研究甜樱桃果实、果柄生长发育及内源激素含量的变化趋势,并探讨GA_(3)+6-BA处理对果实、果柄生长发育及内源激素含量变化的影响。结果表明:甜樱桃果实生长发育期内,果实重量相关性状中单果重、果实纵径和果实横径的动态模型符合Logistic方程,果实重量最大相对生长速率出现的时间在花后28 d左右,果实中ABA、GA_(3)、IAA、ZR含量均呈先下降后上升的变化趋势,果柄与果实内源激素含量变化趋势并不协同;GA_(3)+6-BA配施处理后,促进了甜樱桃果实及果柄的生长,使内源激素IAA、GA_(3)、ZR的含量显著增加,并显著增加了果柄(GA_(3)+ZR+IAA)/ABA值。研究结果为植物生长调节剂在甜樱桃上的应用提供了一定的理论参考依据。We used 7-year-old‘Samito’sweet cherry as the test material to study the growth and development of sweet cherry fruits and fruit stalks,as well as the changes in endogenous hormone content.The effect of GA_(3)+6-BA treatment on the growth and development of fruits and fruit stalks and the changes in endogenous hormone content were also explored.The results showed that during the growth and development period of sweet cherry fruit,the dynamic models of single fruit weight,longitudinal diameter,and transverse diameter in the fruit weight correlation were in accordance with the logistic equation.The maximum growth rate of fruit weight appeared around 28 days after flowering,and the content of ABA,IAA,GA_(3),and ZR in the fruit showed a trend of first decreasing and then increasing,the trend of changes in endogenous hormone content in fruit stems and fruits is not synergistic.After the application of GA_(3)+6-BA,it promoted the growth of sweet cherry fruit and stem,significantly increased the content of endogenous hormones IAA,GA_(3),and ZR,and significantly increased the stem(GA_(3)+ZR+IAA)/ABA value.The results of this study provide a theoretical reference for the application of plant growth regulators on sweet cherries.
