to study the physiological and morphological relationships of two clover species affected by herbicides, pursuit experiment in a factorial based on randomized completely design with 3 replications at the damavand in 2012. the first factor consisted of two species of trifolium pretense l. and trifolium alexandrinum l. and the second factor consisted of three levels of herbicide pursuit (0, 0.5, ...

The photosynthetic apparatus is reorganized during acclimation to various light environments. During adaptation of plants grown under a low-light to high-light environment, the light-harvesting chlorophyll a/b-protein complexes decompose concomitantly with an increase in the core complex of photosystem II. To study the mechanisms for reorganization of photosystems, the assembly of chlorophyll w...

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...
