| Abstract: | Effects of shoot topping and exogenous plant growth regulators on some enzyme activities andnicotine content of roots were studied. The results showed that the activities of ornithine decarboxylase(ODC),putrescine N-methyltransferase (PMT) and N-methylputrescine oxidase (MPO) and nicotine content in toppingplants were higher than those in non-topping plants. Leaf spraying with ABA and 6-BA could increase thenicotine content in topping plants, but leaf spraying with IAA and GA3 significantly decreased nicotine content.The effect of IAA was more than that of GA3. |
| Keywords: | tobacco nicotine ornithine decarboxylase putrescine N-methyltransferase N-methylputrecine oxidase plant growth regulators |
