摘要
水栒子挂果期短、落果频繁,为延长观果期,以5年生水栒子为试验材料,在其果实膨大期,通过不同浓度的赤霉素涂抹果柄及喷洒全树实验,研究激素处理对观果植物挂果期的影响。结果表明:10mg/LGA_3处理,能最大限度延长水栒子观果期,延长20d左右;30mg/L和50mg/LGA_3处理,能使水栒子观果期延长10~15d,在整个生理落果期内,50mg/LGA_3处理整体效果最好,落果率最低。
Short fruit bearing period and fruit dropping frequently in Contoneaster multiflorus.In order to extend the fruit ornamental period,The fruit stems and the whole tree in 5 years' C.multiflorus were sprayed with different concentration of GA_3during developing fruit period,The effects of hormones treatment on the fruit bearing period were studied.The results indicated that 10mg/L GA_3 treatment could extend the maximum fruit ornamental period in C.multiflorus by 20 days;30mg/L and50mg/L GA_3 treatment could extend the fruit ornamental period by 10 to 15 days,50mg/L GA_3 treatment had the best effect as a whole and the lowest fruit dropping rate during the physiological fruit dropping period.
