STORING TECHNIQUE OF THE TEAK STUMP

The store of teak stump,which was used to be studied by Hocking and Nyland in 1971,has been carried out for three years from 1985-1987.We need to accumulate a large amount of nutriment in root of teak seedling.Expanding the main-root and inhibiting the growth of main-shoot can be obtained by decrease of the space,watering and manuring.Since the stump seedlings had turned to dormancy,they were stored in sandy pond where the safe moisture content must be controled.The results showed that after storing for 14 months,the survival percent of planting can be high as 90-100%;after storing for 18 months and packing transportation for 21 days,it still keeps at 83-95%,this storing period is twice as long as that obtained by A.Kaosa-ard in 1975,Thailand.In comparison of the traditional,using teak stump not only decreases the planting costs but also enhances the survival percentage and early growth.This technigue can be able to use in a large scale nursery centre and transplanting in any season.It is the best way for intensive management and breeding,mitigating the contradiction of labours in planting season and solving overwintering of the teak seedlings in high latitudinal districts.
