the effect of automobile pollution was determined on chlorophyll content of four different tree species viz. azadirachta indica l., conocarpus erectus l., guiacum officinale l.and eucalyptus sp. growing along the roads of the city.  significant changes in the level of chlorophyll “a”, chlorophyll “b” and total chlorophyll “a+b” were found in the leaves of four tree species (a. indica, c. erectu...

flaxseed oil is known as a functional oil because of the high content of α-linolenic acid; therefore, the aim of this research was to investigate some physicochemical properties of iranian extra virgin flaxseed oil (evfo) and the impact of the refining stages before deodorization on these properties. fatty acid composition, peroxide and anisidine values, free fatty acids, crystallization point,...

Spatial and temporal variations in canopy structure and leaf biochemistry have considerable influence on fluxes of CO2, water and energy and nutrient cycling in vegetation. Two vegetation indices (VI), NDVI and Macc01, were used to model the spatio-temporal variability of broadleaf chlorophyll content and leaf area index (LAI) across a growing season. Ground data including LAI, hyperspectral le...

The color of plants depends to a great extent on the conditions of nutrition. Approximately fifty years ago VILLE (7) attempted to determine the proper provision of plants with elements of nutrition by their color from the amount of chlorophyll produced. The pale color of plants may depend on various causes. In some cases it is called forth by an actual reduction of the amount of chlorophyll ow...

ABSTRACT Leaf color is used as a guide for assessments of nutrient status and plant’s health. So that a new method is proposed for the detection of Chlorophyll content based on the leaf color. Based on green color present in leaf we can estimate the chlorophyll content in leaf. The proposed equation produced superior results with the true value of chlorophyll content measured in the laboratory ...

green fig, a fruit usually consumed as dried is one of the important non-oil export agricultural commodities of iran. physical properties of green fig are vital parameters as regards the design of such post harvest processing equipments as dryers, sorters and storing chambers. in this research work the effect of moisture content on fruit characteristic dimensions, geometric mean diameter, spher...

to investigate the effect of droughtstress on chlorophyll content, enzymatic responses and some growth characteristics of acacia victoriae seedlings and the effect of super-absorbent polymers (sap) in reducing drought stress, a split plot experiment based on the completely randomized design was conducted. the treatments included four levels of drought stress (15, 30, 60 and 100% of field capaci...
