Increased soil strength due to soil compaction or soil drying is a major limitation to root growth and crop productivity. Roots need to exert higher penetration force, resulting in increased penetration stress when elongating in soils of greater strength. This study aimed to quantify how the genotypic diversity of root tip geometry and root diameter influences root elongation under different le...

in order to study the effects of pgpr application methods on proline and soluble sugars content of yarrow (achillea millefolium l.) under drought stress conditions an experiment was performed at islamic azad university, yadegar-e-imam khomeini (rah) shahre-rey branch. this experiment was carried out in a split plot arrangement with randomized complete block design in three replications. experim...

A new method of irrigation was designed and tested for its water use efficiency (WUE). Maize plants were grown in pots with their roots divided and established into two or three separated containers of which irrigation and soil drying were controlled alternately. Results showed that when the two halves of the root system were alternatively exposed to a drying soil and a soil with its water cont...

Changes in the plant water status, biochemical and hormonal responses, were investigated three olive cultivars (Arbequina, Arbosana Chetoui) grown a super-high-density orchard under partial root-zone drying (PRD) irrigation. Four irrigation treatments applied during two growing seasons (2015 2016); control treatment (100 % ETc) irrigated at 100 of crop evapotranspiration on both parts PRD PRD, ...

This study was carried out to evaluate drought stress tolerance in Thymus kotschyanus accessions using a factorial experiment based on a Completely Randomized Design (CRD) with 5 replications during 2013-2014 in Qom, Iran. The first factor was the accession with 17 levels and the second factor was drought stress with three levels of irrigation including 80% (control), 60% and 40% Field Capacity...

Buchnericin LB produced by Lactobacillus buchneri LB was purified to homogeneity by a rapid and simple three-step purification procedure including freeze drying, silicic acid adsorption/desorption and cation-exchange chromatography. After the silicic acid and cation-exchange chromatography steps, the activity of buchnericin LB was recovered by 85 and 25%, and its purity increased about 111 and ...

to investigate the effects of different salinity levels of nacl on germination of safflower (cv. esfahan 24) seeds under three different incubation methods, a factorial experiment was carried out based on a complete randomize design with three replications. salinity levels were 0, 5, 10, 15 and 20 dsm-1 (nacl) and incubation methods were sandwich method, and using petri dishes with open or clos...

to determine sugar content and root yield variation of new sugar beet hybrids under different irrigation levels, an experiment was carried out at zarghan agricultural research station offars agricultural and natural resources research center, shiraz, iran. the study was conducted as split block based on a randomized complete block design with three replications for two years, 2009-10, using lin...
