IN VITRO GERMINATION OF ANTI-DIABETIC PLANT LOQUAT (Eriobotrya japonica Lindl.) TO PRODUCE GOOD SEEDLING

Abstract

The aim of the study is to obtain good seedling of anti-diabetic plant Loquat (Eriobotrya japonica Lindl.)
through in vitro germination by using growth stimulator of gibberellic acid (GA3) and kinetin. The study is
carried out using a completely randomized design with two factors, the concentrations of GA3 (0, 250 and
500 mg/L) and the kinetin (0, 4, 8 and 12 mg/L). The results showed that the technique has successfully
shortened the germination time of loquat seed and stimulate the growth development of shoots, leaves
and roots. The GA3 and kinetin at optimum condition are found very effective to stimulate seed
germination and growth of loquat seedlings. Combination of 500 mg/L GA3 and 8 mg/L kinetin, followed by
250 mg/L GA3 and 4 mg/L kinetin was observed to be the best experimental condition to produce good
quality seedling. It was also observed that high concentration of 500 mg/L GA3 alone is very effective to
improve the growth of loquat root. The study is promising to obtain good seedling of loquat plants.
