Water deficit stress is the main limiting factor of crop growth and yield in arid and semi-arid environments. Hyssop (Hyssopus officinalis L.) is one of the most important medicinal plants that have numerous medical uses. In order to study the effect of drought stress on physiological and morphological traits of Hyssop, an experiment based on randomized completely design was conducted with four...
Responses of leaf growth and leaf water relations to seasonal drought were monitored during two successive years in three cultivars (Galhosa, Espargal and Mulata) of Ceratonia siliqua L. growing in the field in southern Portugal. Leaf water relations of fully expanded leaves were characterized by pressureâ volume analysis, and morphometric measurements of petiolar xylem were made. The three cu...
In order to investigate the effect of supplementary irrigation on dryland wheat cultivars, an experiment was conducted as a factorial in randomized complete block design with three replications during cropping seasons 2016-2017 and 2017-2018. The factors were drought stress levels (dryland and supplemental irrigation) and wheat cultivars (Homa, Sardari, Rijaw, Ouhadi and Azar2). Supplemental ir...
The study was conducted on physiology and biochemical performance and correlation for yield and its quality characters of 18 genotypes of Glory lily (Gloriosa superba). Experiment was laid out in a randomized block design with three replications at the Medicinal Plants Unit, Botanical Garden, Tamil Nadu Agricultural University, Coimbatore. Genotypes GS 15, GS 06, GS 18, GS 03 and GS 02 were com...
late-season drought is the major constraint reducing the productivity of chickpea. this experiment was carried out to study response of root and shoot characteristics in 12 chickpea genotypes to drought stress. two-drought stress levels (-3 and -6 bar) induced by peg 6000 and control in hydroponic condition at green house was performed. leaf relative water content (rwc), plant height, number of...
To study the effect the effect of foliar application of zinc and calcium on physiological and agronomical characteristics of safflower in lead stress, the experiment was laid out in a factorial based on randomized complete block with three replications at the greenhouse of Agricultural Research center of Kerman. Treatments included four methods of application of lead (control, soil application ...
Dehydration is the most important limiting factor in agricultural production in arid and semi-arid regions, and water shortages (especially at the reproductive stages) due to lack of precipitation and unequal distribution are inappropriate for limiting the yield. In this research, cross between the Gasspard cultivar (dehydrated susceptible parent) and DN11 line (resistant parent) was performed....
Although water and land pollution are very dangerous, air pollution has its own peculiarities due to its transboundary dispersion of pollutants over the entire world. In any well planned urban set up, industrial pollution takes a back seat and vehicular emissions take precedence as the major cause of urban air pollution. In the present study, Air pollution tolerance index was calculated for var...
Six months-old seminal plants of 36 cacao genotypes grown under greenhouse conditions were subjected to two soil water regimes (control and drought) to assess, the effects of water deficit on growth, chemical composition and oxidative stress. In the control, soil moisture was maintained near field capacity with leaf water potentials (ΨWL) ranging from -0.1 to -0.5 MPa. In the drought treatment,...
This study was conducted to evaluate changes in antioxidants, free proline, relative water content and determination of root colonization of four commercial wheat (Triticum aestivum L.) cultivars (Azar2, Darab2, Shiraz, and Falat) inoculated with the fungus Glomus intraradices, under four water regimes of 100, 75, 50, and 25% of field capacity in the year 2010 at the School of Agriculture, Shir...
