Abstract
Quercus semecarpifolia (Smith) serves as a superior food plant of oak tasar silkworm among the other food plants. The seeds (acorn) are damaged by seed borer which creates problem in natural germination. Frequency of nature grown seedling is further decreased by tremendous grazing and heavy lopping so artificial regeneration has to be resorted as an alternative to supplement natural regeneration. Large size seeds collected during the month of June gave better germination (70.00%). Hence, seeds of large size should be collected during June-July just after their ripening for raising nursery for regeneration of Quercus semecarpifolia.
