多效唑对脐橙产量和品质的效应

EFFECT OF PP_(333) ON THE NAVEL ORANGE YIELD AND QUALITY

用三种浓度多效唑在花前一周和花后一周两次喷施15年生华盛顿脐橙,结果表明:100ppm和500ppm多效唑处理可显著提高脐橙有叶单顶枝率,抑制夏梢的抽发,提高脐橙果枝座果率和产量,对脐橙果实品质无任何不良影响。

The effect of PP_333 of three concentrations on Navel Orange (Washington Navel Orange)were studied in this paper. The results showed that 100ppm and 500ppm PP_333 treatments could increase the rate of the single flower shoot with leaves and inhibit the summer shoot sprouting. The setting fruit rate of fruit shoots and the yield of Navel Orange increased after the two concentrations were used on the Navel Orange trees twice each year. PP_333 has not any bad effects on the fruit quality.
