EVALUATING THE EFFECT OF SUBSTRATE AND SOME NUTRITIONAL PRODUCTS ON THE GROWTH AND DEVELOPMENT OF STEMONA TUBEROSA LOUR. IN VITRO IN THE NURSERY STAGE

Abstract

Two experiments were carried out to examine the effect of substrate and plant
nutrients on the growth of the in vitro micropropagation of Stemona tuberosa Lour. in vitro,
at the nursery stage. The experiment was conducted with 4 different substrate formulations
and 3 different nutrient spray formulations. The research results show that: the formula of
sand + soil + manure (3:1:1) gave the highest rate of plantets surviral (85%), and the best
plant growth and development (growth indicators were 8.43 cm height, 1.04 branches, the
root diameter of 1.28 cm, having 4.69 leaves, rate of provided plants reaching 89.42 %.
Using nutrients Đầu trâu MK 701 the rate of plantets survival was 78 %, it also had the best
growth and development (growth indicators were 9.87 cm high, 1.41 branches, the root
diameter of 1.19 cm, 6.37 leaves, the rate of was of 93.09 %
