| Abstract: |
| Two kinds of drought treatments: discontinuous drought treatment(1 h, 2 h, 3 h, 4 h each day) and 24 h continuous drought treatment were adopted to wheat seedlings. Copper and manganese content in different parts of seedlings and chlorophyl
l content were detected to investigate the effect of different drought treatments. The results indicated that the content of copper, manganese and chlorophyll all increased in wheat seedlings under discontinuous drought treatment of 1 h and 2 h, while the treatment of 2 h was more effective. The discontinuous drought treatment of 3 h, 4 h and continuous drought treatment led to decrease of the content of copper, manganese and chl
orophyll, with seedlings of continuous drought treatment decreasing observably. The experiment demonstrated that mild dro
ught treatment could increase the content of copper and manganese in wheat seedlings, while severe drought treatment decreased them. |
