Gibberellin處理가 地黃(Rehmannia glutinosa)의 發芽와 幼植物生長에 미치는 影響
李洪宰 順天大學校 1984 論文集 Vol.3 No.1
A based experiment was done to find what effects Gibberrellin exerts on the germination and seedling growth of Rehmannia glutinosa when it was planted after treating with gibberrellin. The concentration of Gibberellin was divided by of 10, 50, 100, 250, 500 (ppm) and treatment time was differentiated by for 30 minutes and 60 minutes. The results of investigation are summarized as follows. 1. 50ppm/60min and 100ppm/60min treatment groups were most promoting in germination speed and total of germination number. 50ppm/30min and 100ppm/30min groups were less promoting. Both 500ppm/30min and 500ppm/60min groups were inhibiting in them. 2. In the effects on seedling growth, 100ppm/60min treatment group was most promoting, and in the order of 100ppm/30min, 50ppm/60min, 50ppm/30min, the groups showed less promoting effects. The group treated with high concentration (500ppm) was a little promoting in plant height, but on the contrary they was inhibiting in weight of dry matter and emergence.
