| Abstract: |
| To explore the influence of different light media types and proportion on seedling growth，we mixed four types of media in different volume ratio according to the physical and chemical properties. Tinospora sagittata tissue culture seedlings were selected as material. The results showed that when the proportion of
coconut bran, pine bark, peat soil and yellow subsoil were 2:1:1:1 and 2:0:2:1, the survival rate of seedlings was the highest, up to 100%. After 126 d of transplantation, the average seedlings height was the highest in the formula D with the mixture of coconut bran, pine bark, peat soil and yellow subsoil (2:2:1:1). The formula E of the mixture of coconut bran: pine bark: peat soil: yellow subsoil was 2:3:1:1 with the largest mean ground diameter. When the proportion of coconut bran: pine bark: peat soil: yellow subsoil was 1:1:1:1, the mean total root length of seedlings was the longest. Through the comprehensive index analysis, it was concluded that the most suitable formula for the growth of T. sagittata tissue culture seedlings was the mixture of coconut bran: pine bark: peat soil: yellow subsoil with the proportion of 1:1:1:1. |
