Effects of water deficits on leaf turgor maintenance processes were analyzed for pear trees (Pyrus communis L. cv. "Barlett") grown in 120-liter containers. Four irrigation treatments were applied: a well-watered control treatment, a spring water stress cycle (Sp), a summer water stress cycle (Su), and a spring plus summer water stress cycle (Sp + Su). For the Sp treatment, water application wa...

in order to study the effects of conventional and conservation tillage with management residue on wheat physiological properties, a field experiment was conducted in 2013-2014 at mashhad agricultural and natural resources research center of razavi khorasan province. this experiment was carried out as split plot design based on a randomized complete block design with three replications. main plo...

wild jujube, ziziphus lotus, is a multipurpose xerophytic shrub of the rhamnaceae family widely distributed in arid and semi-arid regions of tunisia, where it occupies most soil types. the fruit is the edible part of the plant by local population. the reintroduction of this shrub requires the control of its multiplication in response to water shortage. this study aims to evaluate growth and wat...

The present study was carried out to estimate genetic variability parameters for some traits such as pods per plant, cell membrane stability, one thousand kernel weight, flowering period, grain filling period, chlorophyll content, relative water content, leaf excised water content, seed per pod and pod length, in 16 winter rapeseed genotypes. Statistical analysis showed significant differences ...

7 ABSTRACT: The antioxidant properties of methanolic extracts of six locally consumed plants in Nigeria were comparatively evaluated both in vitro and in vivo. The plants included V. amygdalina (bitter leaf); C. rubens (‘ebolo’); A. hybridus (‘tete’); J. tanjorensis (jatropha); G. africana (‘okazi’) and T. triangulare (water leaf). The in vitro study indicate that the DPPH radical scavenging ac...

Understanding the response of a crop to water deficiency is the first step towards breeding drought-tolerant varieties. In this study, inbred maize (Zea mays L.) line KS140 was subjected to drought stress by withholding water for 10 days at the V5 or V6 leaf stage. Water-deficient plants experienced a decrease in relative leaf water content, stomatal conductance, net CO2 assimilation rate, and ...
