蓖麻摘葉對於植株生長及種子產量之影響

Abstract

(1) In Taiwan, for the purpose of special uses in industry and medicine, the castor bean plant is cultivated from September to July next year, in order to obtain oil from seeds, Since the castor-silkworm or En-silkworm (Philosamia cynthia ricini Eoisduval) was introduced from India, some castor bean cultivators usually pick the leaves to feed them, as a subsidiary source of income, for they can resist unfavorable conditions and can be reared easily.
