Effect of Temperature, Moisture and Weight of Seed-Corm on the Sexual Reproduction of Amorphophallus Konjac K. Coch

Abstract

Abstract: The sexual reproduction of konjac was one of the most effective approaches to accelerate development of planting and improvement of cultivars, and it was attracted particular interest. In this paper, the influence of the temperature and the moisture in continuous 5d after pollen matured, and the weight of seed-corm with bud on the sexual reproduction of Amorphophallus konjac K. Coch was investigated with 117 individual plants. The results indicated that the means of temperature and moisture for the plants with berries developed being of 24℃ and 64%, respectively, were significantly higher than which of no-berries plants, additionally, the weight of the seed-corm or tuber of plants with berries developed was significantly higher, and it was positive correlative to the berries of single plant with the coefficient of r=0.6096 (the No. of samples =29). It suggested that higher temperature and moisture were helpful to the pollen scattering and germinating, and that the nutrients supplied at the periods of konjac sexual reproduction was derived from the seed-corm.
