Some physiological and biochemical changes were measured between embryogenic and non-embryogenic callus obtained from Cardiospermum halicacabum. Combination of auxin with cytokinin was more favourable for high amount of callus formation. 2,4-D played a key role in triggering somatic embryo formation. Embryogenic callus had more total carbohydrate and starch contents, total free amino acids, nuc...
In order to investigate the effect of Piriformospora indica endophyte fungi on quantity and quality of peppermint essential oil and physiological parameters under salt stress, An Research Field experiment of Agricultural Sciences and Natural Resources University of Surrey in 2015 was conducted. Experiment arranged in completely randomized design with three replicates. The experiment was done in...
abstract to investigate the effects of paclobutrazol (pbz) on vegetative and reproductive growth of strawberry cv. selva a factorial experiment in a completely randomized design with three replications was carried out in greenhouse of agriculture college, isfahan university of technology. pbz was applied in two methods, drench and foliar spray, at 0, 0.5, 1, 1.5 and 2 mg active ingredient per p...
The experiment was conducted in 2012 to evaluate the effect of salinity stress on oil percent, oil yield, seed yield and some physiological charactristics on three local populations of castor bean (Ricinus communis L.), at the University of Shahrekord, Iran. Experiment was carried out with three replications in a completely randomized design including five levels of salinity (1.2, 2, 2.6, 3.8 ...
The seasonal distributions of phytoplankton biovolume and chlorophyll a content were monitored for 14 months in a deep oligotrophic, high mountain lake (Redó, Pyrenees). An allometric relationship of chlorophyll with biovolume was found throughout the period studied, with a correlation coefficient of 0.66. However, the relationship changed with season and the taxonomic composition of the phytop...
abstract this study evaluates the iranian pre-university english textbook in terms of needs, objectives, content, and methodology. the study was designed on the qualitative- quantitative survey basis using interviews and questionnaires, a researcher-made textbook evaluation checklist and a needs analysis questionnaire. the textbook evaluation questionnaire was used in this study to elicit the ...
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 ...
This review summarizes the research on physiological responses to flooding of trees in the seasonal black-water wetland of the Mapire River in Venezuela. Inter-annual variability was found during 8 years of sampling, in spite of which a general picture emerged of increased stomatal conductance (gs) and photosynthetic rate (PN) during the flooded period to values as high as or higher than in pla...
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...
