于6月底给澳洲坚果树(Ikaika 种)喷洒浓度为500或1000ppm 的乙烯溶液,在12天内分别使40％和60％的果实脱落。在开花高蜂后38周,用800或400ppm 的乙烯处理,分别在1周和3周内的带壳果产量与对照树(未用乙烯处理)5周后的产量(14.4公斤/树)接近。
Macadamia trees (Ikaika species) were sprayed with ethylene solutions at concentrations of 500 or 1000 ppm at the end of June, leaving 40% and 60% of the fruits peeled off within 12 days, respectively. At 38 weeks after flowering tall bees, treatment with 800 or 400 ppm ethylene resulted in a close to the yield (14.4 kg / tree) of shrubs within 1 week and 3 weeks, respectively, after 5 weeks of control trees (without ethylene treatment) .
