The effect of salinity on growth, photosynthetic pigment content, and alkaloid secondary metabolite accumulation were studied in an economically important medicinal plant, Catharanthus roseus (L.) G. Don., under pot culture conditions. Plants were treated with different concentrations of NaCl, (e.g. 50 and 100 mM) 30, 45, 60, and 75 days after sowing (DAS). The plants were uprooted randomly 90 ...
Soybean (Glycine max) is sensitive to drought stress, and increasing its yield, requires the selection of tolerate varieties which are adapted to semiarid or low water climates of Iran. In this research, the experiment was performed based on a factorial completely randomized design with three replications at 2013. Experimental factors were consisted of 8 genotypes of soybeans and 6 levels of dr...
In a previous paper (l), studies were made of chlorophyll degradation products frequently to be found in leaf extracts. The solation of spectroscopically pure chlorophylls a and b was then considered (2). The logical outcome of these studies is the application of the data to the determination of chlorophyll in extracts. It is complicated by the suggestion that chlorophyll as known to Willstatte...

A comparative study of polypeptide composition and freeze-fracture morphology of chloroplast membranes isolated from different, but photosynthetically active, regions of a romaine lettuce shoot is presented. Chloroplasts prepared from outer dark-green leaves possess a fully developed light-harvesting chlorophyll-protein complex, have low chlorophyll a:b ratios and display fracture faces similar...
In order to investigate the interaction of mycorrhizal fungi and salinity on growth and physiological characteristics of sweet corn, a greenhouse experiment was conducted at College of Agriculture, Shiraz University, in 2014. The experimental design was factorial based on Completely Randomized Design in three replications. Treatments included salinity at four levels (0.4 (control), 4, 7, 10 dS ...
The objective of this study was to evaluate the nutritional role and efficiency of nano and micro Si on photosynthetic parameters and pigments of potato leaves (Agria cv.) in soil less culture. The factorial experiment based on randomized complete block design with three replications was conducted at the research greenhouse, Ferdowsi University of Mashhad in 2013. Treatments were included two s...
A field experiment was conducted with four wheat varieties Raj4134, HD2733, NW 1014 and K9006 for characterization of heat stress tolerance traits under heat stress condition. Heat stress was induced by delayed sowing of 35 days from normal date of sowing so that grain filling stage of wheat could experience severe heat stress. Data related to plant height, chlorophyll content, starch content a...
Effect of gibberellic acid on marigold (Calendula Officinalis L.) was evaluated in a pot culture experiment. A factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. Main factor was foliar application stages (first, second and third) and sub factor included different concentrations of GA3 (0, 50, 150 and 250 mg L...
