Inter-sectional hybrids were successfully obtained by the reciprocal crosses between 11 cultivars (including 6 diploids and 5 tetraploids) of Begonia semperflorens (SS & SSSS genomes) and B. 'Orange Rubra' (RR genome) with the aid of in vitro culture of mature or immature seeds on MS medium containing 0.1 mg l(-1) α-naphthylacetic acid, 0.1 mg l(-1) 6-benzyladenine, 10 mg l(-1) gibberellic acid...

The nomen nudum Begonia hemicardia Elmer ex Merr. (Begonia sect. Petermannia) was coined by A.D.E. in 1915. He annotated one of his collections (14366 from Mount Bulusan, Luzon) the PNH herbarium with name but did not formally publish it. E.D. Merrill 1923 recognised as a synonym binuangensis After thorough studies living and preserved specimens relevant literature, we found to be different B. ...

Like most other plants begonia picta smith contains various secondary metabolites with great potentials. The aim of this paper is to evaluate the phytochemicals by using quantitative and qualitative analysis Petroleum ether , Chloroform, Methanol extracts ,with help standard methods as well solvent residual byGCHS findings from quantification phytochemical screening showed presence alkaloids, f...

Freeze-induced cell tensions were determined by cell water relations in leaves of broadleaf evergreen species and cell cultures of grapes (Vitis spp.) and apple (Malus domestica). Cell tensions increased in response to cold acclimation in leaves of broadleaf evergreen species during extracellular freezing, indicating a higher resistance to cell volume changes during freezing in cold-hardened le...

Background Triacylglycerols (TAGs) are the main seed storage lipids of plants. TAGs chemichal properties are largely dependent on their fatty acid composition. Diacylglycerol Acyltransferase (DGAT) genes encode the main enzymes needed for TAG biosynthesis. Different types of DGAT genes (named DGAT1, DGAT2, DGAT3 and DAcT) have been identified in plants. DGAT1 and DGAT2 are well characterized, b...

ANI, S. & AMINAH, H. 2006. Plantation timber of Maesopsis eminii. Maesopsis eminii (family Rhamnaceae) is a light hardwood timber species. The trees have whitish bole that are straight and cylindrical when grown in plantation and tend to lean towards sunlight when found to grow among other tree species. The sapwood is almost white in colour and the heartwood yellowish when freshly cut, darkenin...
