| 中文摘要: |
| ：以丝瓜荷兰优美为材料，采用不同浓度的矮壮素和乙烯利处理1叶1心期和 2叶1心期的丝瓜幼
苗，以研究其对丝瓜雌花始花节位、节间长度及叶片数增长速度的影响。结果表明：矮壮素处理降低丝瓜第一雌
花节位以1叶期100…mg/L 效果最好，平均比对照降低1节；以2叶期200…mg/L 处理的丝瓜叶片数增长速度最慢，
比对照减少31.71%；以1叶期500…mg/L的矮壮素处理丝瓜茎节间长度最短，比对照缩短86.44%；不同浓度乙烯
利处理效果不同，1叶期100…mg/L 处理降低了丝瓜雌花始花节位，平均比对照降低0.4 节，2叶期200…mg/L乙烯
利处理叶片增长速度最慢，比对照缩短24.51%，1叶期200…mg/L 浓度处理的丝瓜茎节间长度最短，与对照相比缩
短48.65%。 |
| 英文摘要: |
| Luffa seedlings of“ Holland Youmei” with one or two true leaves were sprayed by exogenous chlormequat
chloride and ethephon with different concentrations，to study the effects of exogenous substance on the first female
flower node，growth rate of leave number and internodes length of stem. The results indicated that chlormequat chloride
treatment had the best effect on lowering the first female flower node with concentration of 100 mg/L at one-leaf stage
and decreasing by one node，inhabiting the growth rate of leaf number with concentration of 200 mg/L at two-leaf stage
by 31.71%，shortening the stem internodes length with concentration of 500 mg/L at one-leaf stage by 86.44%，compared
to the control. Different concentrations of ethephon had different effects，with a decrease of the first female flower node
by 0.4 node with concentration of 100 mg/L at one-leaf stage，an reduce of the growth rate of leaf number by 31.71% with
concentration of 200 mg/L at two-leaf stage，a shortening of the stem internodes length by 48.65% with concentration of
500 mg/L at one-leaf stage，compared to the control. |
