Leaf area is a key variable in the study of physiology, horticulture and crop science It is major parameter in plant modelling studies, to develop physiological model in plant breeding. The plant Putranjiva roxburghii and Morinda citrifolia L.(Medicinal plants) were selected and the leaves of these plants were used for development of linear model for leaf area using Counting grid method. Leaf samples were randomly selected from the lower, middle and upper parts of the plant with different sizes of Leaves. Length, width, L², W², product of these dimensions and leaf fresh and dry weights and...

La surface foliaire est une variable clé dans l'étude de la physiologie, de l'horticulture et de la science des cultures. C'est un paramètre majeur dans les études de modélisation des plantes, pour développer un modèle physiologique dans l'amélioration des plantes. Les plantes Putranjiva roxburghii et Morinda citrifolia L. (plantes médicinales) ont été sélectionnées et les feuilles de ces plantes ont été utilisées pour développer un modèle linéaire pour la surface foliaire en utilisant la méthode de la grille de comptage. Les échantillons de feuilles ont été choisis au...

The medicinal plants play a major role and constitute their backbone in almost all the traditional systems of medicine. The focus on medicinal plants is increased in past few years. In this book, estimation of chlorophyll content, antioxidant potential, measurement of growth by different physical parameters and separation of phenolic compounds of selected medicinal plants were done by using reverse phase high pressure liquid chromatography (RP-HPLC). The main objectives of this study are (1) To understand, at which stage the selected medicinal plans have maximum antioxidant activities and the...
