Pereskia aculeata and Pereskia grandifolia have been studied widely due to their high nutritional and therapeutic values.
However, little is known about the biological requirements of their seeds for the various germination factors. The aim of ecofisiologia vegetal larcher pdf download study was to investigate the effects of predicted temperature increases and drought conditions of Mediterranean environments on N 2 -fixing alfalfa plants.
The inhibitory effect of elevated temperature on plant growth was a consequence of dowbload CO 2 and N 2 fixation rates.
An absence of differences in photosynthesis in relation to water availability suggests that drought decreased plant growth due to its negative effect on leaf area.
Abstract Pereskia aculeata and Pereskia grandifolia have been studied widely due ecofisiologia vegetal larcher pdf download their high nutritional and therapeutic values. After verification of the existence of differences in the performance of germination, a non-linear regression was carried out, relating the germination to temperature and identifying its point ecofisiologia vegetal larcher pdf download maximum efficiency.
Elevated temperature inhibited nodule activity drastically, whereas the inhibitory effect resulting from drought centred on nodule dry mass DM veggetal. Elevated temperature and drought reduced plant dry mass and leaf area, especially when both stresses were combined. Rising temperature and drought affected the nitrogen content negatively, although effects differed. A photosynthetic decrease resulted from the inhibition of rubisco activity, probably associated with a lower activation state.

The germination performance in function of the germination temperature could be described by the Weibull distribution model. Graphical abstract Download full-size image.
