Calcium and potassium are essential nutrients that play a significant role in increasing yield, quality and postharvest properties of many fruits and vegetables. The role of these nutrients in improving quality and quantity of fleshy fruits is important and their interaction on plants such as cantaloupe is less understood. In this research the effects of calcium (0 and 3 g/L) and potassium (0, ...
Myrtle ) Myrtus communis L.) is a diploid plant belongs to the family of Myrtaceae and is considered as one of the important medicinal and ornamental plant. The present was performed to investigate the effect of salinity stress on morphological and physiological traits in myrtle. This study was conducted in an experiment of split plot in time according to a randomized complete block desig...
This research was carried out to evaluate the effect of two mycorrhiza species on growth, yield and oil content of geranium under salinity stress. The experiment was done at research greenhouse of Faculty of Agriculture, Lorestan University, Iran, in 2014. Four levels of substrate (sterilised and non-sterilised control soil and sterilised soil inoculated with Glomus mosseae or G. intraradices),...
We tested the hypothesis that reduced root cortical cell file number (CCFN) would improve drought tolerance in maize (Zea mays) by reducing the metabolic costs of soil exploration. Maize genotypes with contrasting CCFN were grown under well-watered and water-stressed conditions in greenhouse mesocosms and in the field in the United States and Malawi. CCFN ranged from six to 19 among maize genot...
The aim of this study was to determine the effects of water stress on the anatomy of xylem and phloem vessels, mesophyll and epidermal cells, relative water content and ion transfer rate of two wheat cultivars including Azar2 as drought tolerant and Shole as drought susceptible cultivars at four leaf stages. Seeds were sown in pots under normal (soil water content at 100% of FC) and the water s...
Water deficiency stress as the most important abiotic stress plays an important role in the yield suppression of plants worldwide. Considering physiological indices to improve drought resistance is of paramount importance. The objective of present study was to evaluate the effects of different irrigation intervals (irrigation after 5, 7, 9 and 11 days) and rates of superabsorbent polymer (Nil, ...
A portable unilateral nuclear magnetic resonance (NMR) instrument was used to detect in field conditions the water status of leaves of herbaceous crops (Zea mays, Phaseolus vulgaris), mesophyllous trees (Populus nigra), and natural Mediterranean vegetation characterized by water-spending shrubs (Cistus incanus) and water-saving sclerophyllous trees (Quercus ilex). A good relationship was observ...
an experiment was conducted to determine the effect of paclobutrazol (pbz) and different irrigation amount on growth of aerial parts, leaf minerals and root performance in young olive plants cv. ‘manzanillo’ in the department of horticulture, faculty of agriculture, tarbiat modarres university in 2000. a split plot experiment in time was used based on a completely randomized block design with f...
In order to study the effect of seed priming on morphophysiological characteristics of seedlings of chickpea (Cicer arietinum L.) under salinity stress, a factorial experiment based on completely randomized design with three replications was conducted at the Research Center for Plant Sciences, Ferdowsi University of Mashhad, Iran, in 2011. In this study, osmotic solutions of NaCl with electri...
