Effect of paclobutrazol on growth and root morphology of 12 crossed stevia in Vitro

Abstract

Stevia (Stevia rebaudiana Bertoni) is a low-calorie alternative sweetener. The superior varieties of Stevia in Indonesia are limited. Availability of seeds plays an important role in the Stevia plant breeding program for both the selection stage and the production of high-yielding varieties. Tissue culture is the best method of Stevia propagation, but the low adaptability of plantlets causes death in the acclimatization phase. The growth and root morphology of 12 crossbreed Stevia were evaluated. A Completely Randomized Design was used with factorial consisting of two factors were Stevia genotypes (STG1,
