| Description |
The application of betaine, a quaternary ammonium
compound influenced the micropropagation in two
commercially important UPASI (U-9 and U-10) cultivars
of tea. Growth and multiplication of shoots of both the
cultivars was enhanced significantly in the presence of
125–1,000 mg l-1 betainewith best response at 1,000 mg l-1
betaine. The shoots turned brown and died within 15 days
when 1,500 mg l-1 betaine was applied. The study showed
faster water/nutrient uptake in the presence of betaine.Higher
assimilation of carbon and nitrogen in the presence of betaine
was also indicated in biochemical analyses. Thus, a decrease
in carbohydrates coupled with an increase in nitrate reductase
activity was recorded. Moreover, faster differentiation of
vascular elements and shoot thickness was observed in the
shoots of U-9 and U-10 growing on medium containing
1,000 mg l-1 betaine. Nutrient uptake, assimilation and
growth were significantly higher in U-10 as compared to U-9
shoots
