Effects of Harvesting Intensities on Fruit Production and Regeneration of Emblica officinalis Gaertn. in a Semi-Evergreen Forest of Manipur, India

摘要

The fruit production and regeneration status of Emblica officinalis was studied under two harvesting regimes during 2015-16 in a semi-evergreen forest of Manipur. The fruit production varied significantly (p>0.05) between harvesting regimes and years,attaining higher values in low harvesting regime than high harvesting regime, in line with other growth attributes which to contributed to fruit production. A relatively higher proporation of trees were found moderated and highly damaged in high intensity harvesting than the low intensity harvesting stand. Lower annual mortality rate (6.89%) coupled with an increased recruitment (21.52%) in the low harvesting stand resulted in better regeneration although both stands had same pattern of seedl-ings>saplings>trees. The results were further supported by increase soil organic carbon and availableN and K in low intensity stand irr bringing better regeneration.
