Abstract
Abstract:Teaflushshootscomprisingthreeleavesandabudwerecollectedfromvariousclones(cultivars)from different experimental fields and analysed for nitrate reductase (NR) activity. Most of the cultivarsof Assam type had higher NR activity, followed by Cambod and China types. NR activity was maximum inthe clone UPASI-9. It was found that NR activity could be used as a biochemical tool to predict the yieldpotential of cultivars at the initial stage of selection for a breeding programme. The activity was higher inthe youngest part of the tea plant. With the existing methodology it was not possible to measure the NRactivity in stem portions of the tea plant. There was a strong positive correlation between NR activity andamino acid contents of tea shoots. Inclusion of molybdenum in the foliar applied micronutrient mixturewas found helpful in triggering the NR activity in a few clones and seedlings. 2004 Society of Chemical Industry Keywords: tea shoots; NR activity; micronutrients; amino acids; leaf N
