Studies on the reproductive biology of weeds in Malaysia - anther sterility in Mimosa invisa

Baki B.B., . and Prakash N., . Studies on the reproductive biology of weeds in Malaysia - anther sterility in Mimosa invisa. pp. 13-16. ISSN 0216-8236

Histological studies were carried out to ascertain the probable mechanism behind the high rates of floral and/or fruit abortion prevailing in giant mimosa (Mimosa invisa Mart. ex Colla) populations in the northern states of Perlis Penang Kedah and Perak in Peninsular Malaysia. Despite normal initiation of both gynoecium and androecium in the floral bud among M. invisa populations from Penang the microsporangia do not develop the sporangenous tissue. This together with sterile anthers enclosed in a well-defined epidermis and the ill-developed stamens probably contribute to the lack of fruit set in certain giant mimosa populations

Abstract

Histological studies were carried out to ascertain the probable mechanism behind the high rates of floral and/or fruit abortion prevailing in giant mimosa (Mimosa invisa Mart. ex Colla) populations in the northern states of Perlis Penang Kedah and Perak in Peninsular Malaysia. Despite normal initiation of both gynoecium and androecium in the floral bud among M. invisa populations from Penang the microsporangia do not develop the sporangenous tissue. This together with sterile anthers enclosed in a well-defined epidermis and the ill-developed stamens probably contribute to the lack of fruit set in certain giant mimosa populations
