Variation in camptothecin content in Camptotheca acuminata leaves
Variations in camptothecin (CPT) content in relation to leaf characteristics namely leaf area, leaf biomass, and specific leaf area (leaf area divided by leaf biomass), and the influence of climatic factors on CPT content in saplings of Camptotheca acuminata Decne. were studied. Leaf area and CPT content showed a logarithmic relationship in young leaves similar to that between leaf biomass and ...
متن کاملDiurnal variation of asparaginase in developing pea leaves.
Levels of asparaginase activity from developing pea leaves (Pisum sativum) were found to change on a daily basis, increasing during the light period and decreasing in the dark. During extended periods of light, high levels of activity were maintained, while prolonged dark reduced activity to a low value. Half-expanded leaves exhibited the greatest change in activity over the photoperiod. Very y...

15 صفحه اولVariation of N natural abundance in leaves and nodules of actinorhizal shrubs in Northwest Patagonia
This study was performed to assess the N2-fixing capability of the native actinorhizal species Ochetophila trinervis (sin. Discaria trinervis) and Discaria chacaye (Rhamnaceae) in Northwest Patagonia. We measured the N concentration and N natural abundance in leaves and nodules of O. trinervis and D. chacaye, in leaves of associated non-actinorhizal vegetation, and in the soils under each sampl...
متن کاملVariation in the Essential Oils in Different Leaves of Basil (Ocimum basilicum L.) at Day Time
Essential oil molecules released from fresh leaves of sweet basil (Ocimum basilicum L.) were collected in Tenax traps and analysed using a TD-GC/MS. During daytime from 09.00 to 17.00, there were no differences in the content and composition of total essential oils, however the percentage of eugenol increased slightly. Significant differences were found in both the total content and composition...
