Study on the artificial breeding techniques in Ternstroemia gymnnanthera, an important industrial tanning plant

摘要

Ternstroemia gymnnanthera is an important plant for industrial raw material of tanning. The systematic artificial breeding techniques are studied. The seeds and the cutting propagation had been carried out in our lab for two years,There is dormancy period of 3 to 4 months for the mature seeds.we found the dormancy is related to its seed coat and red aril. The seed's nutrients are stored in the cotyledons. The seed coat artificially broken and GA3 (700mg/L) or NAA (100mg/L) treatment can promote seed germination rate. The seed germination is a good way for seedling nursery. The different treatments had done for cuttings to make the seedling nursery and the treatment with NAA (100mg/L) and ABT can significantly improve the cuttings survival rate of two years.Three wild populations of this species were studied in field. We found it adapted to sun environment better than the half shade or shade environment, as in the shade environment, it can not be normally flowering and bearing fruit.
