Research on the deployment of the physiological processes during the growth and the fruiting of the Cucurbita pepo species

Abstract

In this study it was evaluated the development of the physiological characterization of Cucurbita pepo plants during their growth and development, as well as on the mode of physiological adaptation of the plants to the photosynthesis. The research was conducted in the experimental field of the Department of Horticulture , in the USAMV , V. Adamachi farm. Chlorophyll and carotenoid pigments study emphasizes quantitative and qualitative presence of these pigments as a fundamental expression of plant adaptation to environmental conditions .Among the new culture were highlighted some differences, but overall, they have a special significance, showing that some photosynthetic activity cultivation are distinctly different. More interesting are the results that show that the pigment chlorophyll a levels was the highest at the top of plant (about 0.50 equivalent units) and what is particularly interesting in binding phenophase fruit. As was natural data show that levels of chlorophyll is smaller towards the base of the plant and fruit maturity phenophase (about 0.30 equivalent units).
