Allelopathic influences of Michelia champaca and Schima khasiana were tested in bioassay on two cereal crops (maize-Zea mays paddy-Oryza sativa), legume food (rice bean- Vigna umbellata soybean- Glycine max). The aqueous leaf extracts fresh dried leaves above tree species suppressed the growth test crops. study revealed that are least toxic to germination, yield various Although, germination pa...

A origem biossintética das unidades isoprênicas do 4-nerolidilcatecol (1), principal metabólito secundário de Potomorphe umbellata, foi investigada através da incorporação de glicose marcada com [C] e [C], e com precursores das vias mevalonoídica e triose/piruvato, incluindo mevalonolactona-[2-C] e 3-fosfato de gliceraldeído-[U-C], respectivamente. O padrão de incorporação de glicose-[1-C] em 1...
