Summary
Nitrate reductase activity of the terminal bud of tea shoots was greater than that in mature leaves, and exhibited greater activity in triethanolamine HCl−KOH buffer than in phosphate or Clark and Lubs buffers. There was some correlation between yield characteristics of different tea clones and the level of nitrate reductase activity in the terminal bud, and mulching of plants was found to cause a significant increase in activity of the enzyme.
