UV-B-induced damage in such leaves could be reduced with 0.5 mmol.L-1 NaHSO3 treatment; brown spots on the leaf surface were reduced in number, the degree of leaf wilt was reduced, degradation of chlorophyll and carotinoid was reduced and flavonoid level was increased. With the NaHSO3 treatment, the content of H2O2 in leaves of Phaseolus vulgaris under enhanc ed UV-B radiation was significantly lower than in controls, and the activities of antioxidant enzymes were higher with treatment than in controls.

The results showed that plant height increasing speed was significantly slow at the former and middle stage when K level was above 180 kg/hm2.On the contrary,the height of case-hardened plant improved markedly.When the K level was above 135 kg/hm2,the stem girth and maximal leaf area differed significantly as compared with CK,so did LAI.Yield and product value per unit area took the first place when 180 kg/hm2 potassium was used.Average price and proportion of middle and first grade tobacco leaf of 225 kg/hm2 potassium treatment were the highest as compared with other treatments and CK.Four economic characters of the two treatments differed at obvious significant level as companied with CK.The total sugar and K2O were increased,nicotine, total N,protein and Cl- were decreased with increased K levels.The potassium lacked symptom was alleviated with increased K levels,no symptoms was observed when 180 kg/hm2 potassium was used,the degree of weather infected fleck was decreased when the K levels was increased.

The influences of decay coefficient of the cavity and the intensity of the field on the phase distribution as well as its fluctuation are discussed.The results show:if there is absence of the phase damping,the phase distribution oscillates with the period π/λ.It presents single leaf at t=nπ/λ,but it splits into multi-leaf construction during the evolution period due to the interaction between the field and the atoms.
