PHYSIOLOGICAL AND BIOCHEMICAL CHANGES IN TOMATO HYBRIDS IN THE GROWING PERIOD
The tomato is known as a major source of important nutrients including lycopene, B-carotene, flavonoids and vitamin C. Since the discovery that lycopene has anti-oxidative and anti-cancer properties, tomato is considered a protective food, therefore it acquired great popularity among consumers.
Fruit growth and ripening are the result of multiple physiological and metabolical processes that occur during the plant development. Researches regarding the intensity of photosynthesis, as well as the content in assimilatory pigments, dry matter and water in leaves have been made on some tomato hybrids cultivated in protected spaces in different stages of growth: leaf stage, flowering stage and fruiting stage. It was noted that the evolution of physiological and biochemical parameters vary depending on type of tomato hybrid and on the phenological phase.
