abstract background and objectives: soil salinity is one of the most important limited factors of plant productions. physiological drought resulting from salinity stress is one of the main reasons of limiting water absorption from soil. moreover, increasing the salt absorption by plants cause to disorder in physiological and cellular processes. spearmint (mentha spicata l.) is from lamiaceae fa...

Verticillium dahliae Kleb.is a soilborne pathogen that cause vascular wilt in chrysanthemumplant (Dendranthema grandiflorum (Ramat.) Kitam). The objective of this research was to study the levels of some organic solutes, such as total protein, total soluble sugars, starch and proline, relative water content, RNA level, malondialdehyde and H2O2 contents in leaves of chrysanthemuminoculated with ...

Changes in dry matter and water-soluble carbohydrate components, especially fructan, were examined in the basal 25 mm of expanding leaf blades of tall fescue (Festuca arundinacea Schreb.) to assess their roles in plant response to water deficit. Water was withheld from vegetative plants grown in soil in controlled-environment chambers. As stress progressed, leaf elongation rate decreased sooner...

To evaluate the effect of ascorbate and gibberellin on some morphological traits and relative water content of medicinal plant fenugreek in different levels of salinity, an experiment was carried out in Shahr- e - Rey branch of Islamic Azad University in October 2012. The experiment was arranged as factorial experiment in the basis of completely randomized design with four replications. The exp...

some of the morpho-physiological characteristics related to the leaf growth and development of phaseolus vulgaris l. genotypes have been studied in the field conditions at the seed and plant improvement institute (spii). the study was performed as split plot experiment in a randomized complete block design with four replications in well-watered and water deficit conditions with eight genotypes ...

abstract three pear genotypes (nazkeh, lasoreh and qevilah), grown in 2l containers, were studied under four irrigation regimes in order to evaluate the leaf relative water content (rwc), photosynthesis, leaf gas exchanges and plant dry weight induced by water stress. control treatment everyday was irrigation. irrigation was practiced when soil water potential reached at -0.4, -0.8, and -1.2 mp...
