Influence of some bioregulators on quality traits of pruned tea (Camellia sinensis (L) O Kuntze)
1998
Chandra, K. | Pandey, R.
During investigation, it was observed that all the applied bioregulators, namely, jibika, IAA, cycocel, thiourea, methanol, succinic acid and sucrose, have a significant effect on quality parameters such as polyphenol oxidase (PPO) activity, caffeine, crude protein, starch, nitrogen, carotenoid and ascorbic acid (vitamin C) content over the control. However, maximum PPO activity was observed with cycocel followed by succinic acid, jibika, thiourea and sucrose during the first phase of spray while at the second phase PPO was maximal in sucrose-treated bushes followed by cycocel, jibika, thiourea and succinic acid. The caffeine content was found to be maximal in methanol followed by cycocel, IAA, thiourea and jibika as compared to the control during the first phase of spray. Similarly, nitrogen content increased due to methanol application at both the phases. Starch and carotenoid content were significantly influenced by jibika treatment. Likewise, ascorbic acid content was highest in sucrose-treated bushes as compared to other treatments.
