The Growth Difference of Moringa Oleifera and Its Improved Varieties Under Facilities in North China
摘要
Abstract
Moringa oleifera Lam., PKM1 and PKM2 were planted in the greenhouse. In order to select suitable varieties for growing in the north of China, some characteristics which including the seedling growth, nutrient content, and photosynthesis were analyzed. The results showed that PKM1 was significantly faster than Moringa oleifera and PKM2 (p<0.05) on plant height growth and ground diameter growth. In 71 days, the plant average height of the three varieties was 115.7, 80.2, 81.0 cm and the ground diameter was 17.47, 13.27, 15.08 mm, respectively. During the growth season, the nutrient status of PKM1 was better than that of M. oleifera and PKM2. In May, the contents of nitrogen (44.32 mg/g) and potassium (12.73 mg/g) in the leaves of PKM1 were significantly higher than thato of PKM2 and Moringa oleifera, while there were no significant difference on the contents of phosphorus and soluble sugar among PKM1, Moringa oleifera and PKM2; In July, the soluble sugar content of PKM1 was significantly higher than that of the others. On the photosynthetic characteristics, the three varieties had no significant difference on quantum efficiency and light compensation ability under weak light. But with increasing of light intensity, the quantum efficiency had significant difference. PKM1 was significantly higher than M. oleifera and PKM2 in the maximum photosynthetic rate, which was up to 23.84μmol CO2/(m2·s). So PKM1 was the best species in growth and development potential among the investigated plants, and It was suitable for planting under conditions facility in North China.关键词
