background: diabetes mellitus is a chronic disease. decreasing postprandial hyperglycemia by retarding glucose absorption through inhibiting carbohydrates digesting enzymes (α-amylase and α-glucosidase) is one of many approaches used for the management of this disease. this study was aimed at evaluating the normoglycaemic potential of helianthus annuus leaf. methods: the effect of the in vitro ...

The temperature sensitivity is reported for the latent period preceding ethylene-induced elongation in the adaxial half of the leaf petiole of Helianthus annuus. When intact plants were exposed to 10 mul of ethylene/l of air over the temperature range 18 to 35 C, the minimum latent time was 62 minutes at 28 C and the maximum was 132 minutes at 18 C. The temperature coefficient, Q(10), changed f...

in this study, cercospora sp.on olea europaea and pseudocercospora mori on morus alba are being recorded from iran. moreover, new reports were provided for cercospora apii s.l. (including c. canescens,c. citrullina, c. morina, c. sonchi, c. cruciferarumand c. helianthicola), and pseudocercospora rubi. also, helianthus sp., morus alba,raphanus sp. and taraxacum sp. are reported as new hosts forc...
