Results of studing on meristem and reproduction KS4 taro by in - vitro
The most common reproduction method for taro is by vegetative cuttings, with low propagation rates and disease dissemination. Therefore, requiring the of pathogen free plants of taro is needed. The aim of this work was to identify optimal conditions for invitro micropropagation of taro plants. In order to reach the aim, corms were surface sterilized with HgCl2 0,1%. To establish the invitro plantlets, meristems were cultured in MS + 0,1 ppm BA - 0,01 ppm NAA+ 20g/l sucrose + 6g/l agar. The best proliferation rates were obtained with MS + 3ppm BA + 0,5ppm IAA + 30g/l sucrose + 6g/l agar (3,0 plants/explant/4 weeks). The highest survival percentage of plantlets was recorded in media with alluvium and burned rice husk mixture (1:1 ratio) with 96,2%.
