喷施乙烯利对‘HAES900’澳洲坚果果实脱落和品质的影响
The Effect of Ethephon Spraying on the Fruit Abscission and Quality of Macadamia Cultivar ‘HAES900’
摘要
Abstract
In order to reduce the cost and difficulty of macadamia harvesting,the cultivar ‘HAES900’ was used as material,the ethephon solution which at the low concentration gradients of 0.40 g/L,0.65 g/L,0.90 g/L and high concentration gradients of 0.80 g/L,1.30 g/L,1.80 g/L were sprayed on the macadamia tree in fruit maturation period,the fruit abscission rate after ethephon spraying were investigated,the fruit quality and adhesive force of fruit stem were determined.The results showed that the low concentration ethephon solution spraying can promote the macadamia fruit abscission,but the fruit abscission rate can not meet the production requirement.The fruit abscission rate of 2 weeks and 4 weeks after the ethephon solution spraying of 1.80 g/L were 98.75％ and 100.00％,respectively.The adhesive force of fruit stem after spraying of high concentration gradients of ethephon solution were reduced significantly,the degree of correlation of the adhesive force of fruit stem and the fruit abscission rate was very significantly.The result indicated that the adhesive force of fruit stem could be used as the indicator to judge the suitable harvest time of macadamia.The water content of shelled nuts,single nut weight,average diameter of nuts,single kernel weight,kernel rate and first class kernel rate have not been affected by this method,the method could shorten the harvest period and reduce the harvest cost significantly.关键词
