BUZZ-POLLINATION IN TRICHODESMA-INDICUM (L) R-BR (BORAGINACEAE)

Trichodesma indicum (L.) R. Br. (Boraginaceae) flowers throughout the year. flower was protandrous and remained in bloom for +/- 3 days. Buz z-pollination was carried out sternotribically by two species of Antho phora (Apidae). Pollen - ovule ratio and breeding experiments (hand-po llination treatments) revealed it as a facultative xenogamous species. It is a non-apomictic species as except emasculation treatment for ap omixis, all the hand pollination treatments resulted in normal fruit a nd seed set.
