The Appearance Of Mutations From Three Varieties Of Longan Used Gamma Rays

Abstract

The need for fruit in Indonesia is increasing every year along with the increase in population. The increasing demand for longan fruit with good quality and small seeds (seedless), it is necessary to plant breeding. Longan plant improvement can be done by various methods, one of which is mutation method with gamma ray radiation. This study aims to determine the diversity of longan plant mutants and changes in the character of longan plants due to mutations of gamma ray radiation. In this study, three varieties were used, namely longan Itoh, Wusan, and Kateki with two doses of gamma irradiation, namely 50 and 60 gray (Gy). There are changes in plants, namely in the morphological character and the rate of photosynthesis. The percentage of vegetative propragation was 1%.

Histological and Physiological Effects of Treatment of Rudbeckia hirta with Gamma Radiation

“…Callus growth was maximal at 20 Gy but decreased at 100 Gy [ 27 ]. In the case of Dimocarpus longan J. de Lour., gamma radiation modified the morphological features and the rate of photosynthesis [ 28 ].…”
