Abstract
[Objective] The aim was to reveal the effects of ethephon treatment on the agronomical,physiological and biochemical characteristics of cucumber.[Method] JINCHUN No.4 cucumber grown in solar greenhouse was used for experiment,and the changes of agronomical,physiological and biochemical characteristics were studied by treating with different concentration ethephon in two-leaf and four-leaf period of seedlings.[Result] The results indicated that an appropriate concentration of ethephon within 50-150 μl/L could restrain effectively seedling to grow rapidly.At the same time,the female flowers within 1-10 nodes for treatment in two-leaf period and those within 11-20 nodes for treatment in four-leaf period increased obviously,and the position of the first female flower declined.Furthermore,the appropriate concentration of ethephon could make the physiological and biochemical characteristics of functional leaves retained at higher level.It was showed that the ethephon treatment increased the contents of soluble protein(Pr),chlorophyll(Chl) and carotenoid(Car) obviously,as well as the activities of superoxide dismutase(SOD),peroxidase(POD) and the photosynthetic rate(Pn),but decreased the content of malondialdehyde(MDA).In addition,the prophase yield increased,but single fruit weight of treated plants was lower,and some nutrient component declined on the condition that the fertilizer and water is not enough.[Conclusion] The ethephon treatment could improve the agronomical,physiological and biochemical characteristics of cucumber effectively.
