Effect on flower thinning by using nano-processing technology chemicals in plum (Prunus salicina Linnaeus)

Abstract

In this study, we investigated the effect of flower thinning chemicals using wet nano-technology on the rate of flower thinning and yield of high-quality fruit. We confirming the flower thinning rate, crop load and fruit set rate, the rate of flower thinning of 500 times and 250 times diluted solution was 5.7 times and 3.8 times higher than that of the control, respectively and the fruit set rate was 2.2 times, 3.4 times. To confirm the fruit quality characteristics of the plums of different cultivars, we sprayed the flower thinning chemicals prepared through the nano-processing on the Royaldaeseok, Formosa and Hongosen cultivars and compared the crop load, fruit weight and fruit size. Overall, the fruit weight and fruit size were higher in the plums of all cultivars sprayed with flower thinning chemicals than the control group. We were concluded that the use of flower thinning chemicals by wet nano-process technology could inhibit the number of fruit set and produce high-quality fruit in fruit trees other than plums. In addition, it is expected to be applicable to various fields because it can be used in natural products and bio industries as well as plant nutrients.
