不同浓度蔗糖预措处理之瓶插寿命与对照组并无显著差异，无法延长嘉德丽雅兰切花之瓶插寿命。

The cattleya cut flower treated with 0.1 ppm, 1 ppm and 5 ppm ethylene for 24 hrs at 25℃compared with the control. The control had normal flower at 2nd day after treating, but 0.1ppm ethylene treatment had slight wilt in the petal and still had ornamental value. Treatments with 1 ppm and 5 ppm ethylene had complete wilt in the corolla and lost ornamental value. The treatments with different concentration of ethylene caused considerable flower senescence, the decrease of water uptake and fresh weight of cattleya cut flower in the vase. Data showed that cattleya cut flower was one of orchids very sensitive to ethylene response.

In order to research the effects of minimum tillage and no-tillage patterns on yield and senescence of flag leaf of winter wheat, four tillage patterns were adopted in Longkou city, Shandong Province, China for three years. Four tillage patterns were as follows: conventional tillage with straw turnover, rotary tillage with straw turnover, serrated disk harrow tillage with straw turnover, no-tillage with straw cover. Effects of different tillage patterns on the activities of superoxide dismutase, peroxidase and the contents of malondialdehyde and soluble protein of the winter wheat flag leaves after anthesis were analyzed.
