Effects of CCC on Transplant Quality and Fruit Yield of Tomato
Lu Guoyi Cheng Zhihui (.Department of Horticulture')
Seedlings of tomato (Lycopercicon esculentum) cv. Xinong 72-4, raised in electric frame, were transplanted in a plastic green house at the 2 ture leaf stage,and sprayed with CCC (chlormequat) at 0.05%,0.1%,0.2% or 0.4% at the 3 true leaf stage and at the 4 ture leaf stage respectively. The results showed that treatment with CCC at 0.1% gave the best result in transplant quality, short stocky plants with a good root system were produced, and the treated plants also had high dry matter and seedling index. All treatments reduced plant height and leaf area but increased leaf thickness in relation to the water-treated control, this trend is accompanied by the increase of CCC concentration. The early and total yield of fruits treated with CCC were similar to those of water-treated control plants.
