INVESTIGATION OF BAUHINIA BLAKEANA DUNN. A HYBRID SPECIES

Bauhinia blakeana Dunn. is a hybrid belonging to Family Caesalpiniaceae, tribe Cercideae. Studies of Morphological characters, cytological characters and phytochemical screening of leaf aterials of B. blakeana and it sparental species have been carried out. The putative parental species shared many morphological similarities with B. blakeana. Average chiasmata per bivalent were intermediate between B. purpurea and B. variegata. Two common flavonols viz. kaempferol, quercetin (Quercetin-3-rhamnosides) were detected in all the species while isorhamnetin was detected in B. blakeana and B. purpurea. Apigenin was present in all the species. Flavonols (spots 7, 18) were common in B. blakeana and B. purpurea and (spot 5) in B. blakeana and B. variegate while (spot 10) was common in B. purpurea and B. variegata. Results of the present study showed complementation of their putative parental species.
