Moisture Stress and Root Volume Influence Transplant Shock: Preliminary Results
نویسندگان
چکیده
-Despite evidence of its economic impact, very little is known about transplant shock. This study was designed to evaluate transplant shock in relation to root volume and soil water content for two year-old Douglas-fir seedlings. Preliminary results found that new growth decreased and days to budbreak increased with higher moisture stress. This effect was most pronounced for high root volume seedlings in the driest soil. Forthcoming results are expected to further implicate moisture stress as an influencing factor in transplant shock.

Effect of Cucurbita Rootstocks and Water Deficit on Growth Properties and Yield of Cucumber
Water supply in arid and semiarid regions of the world is a serious problem in crop production. Grafting may enhance water stress resistance and plants growth. In order to evaluate the effect of different cucurbit rootstocks (Flexifort, Shintoza and ungrafted cucumber) and water stress (40, 60, 90% of field capacity) on morphologic traits and yield of greenhouse cucumber (Cucumis sativus L. var...

Responses of above and below-ground traits of wheat wild relative (Aegilops tauschii) and bread wheat (Triticum aestivum L.) to imposed moisture stress
The narrow genetic variation of bread wheat is one of the limitations to improve it for drought-tolerance. The research carried out to study the responses of different genotypes and traits to imposed moisture stress. The plant material comprised of 10 Aegilops tauschii accessions as well as a tolerant (BW2) and a susceptible (BW1) bread wheat cultivar. To assess the root and shoot-traits, two s...

Plant roots, with respect to their intrinsic characteristics, have important role in both improvement and development of germplasms of drought resistant plants. This experiment was conducted to study direct and indirect effects of root morphological traits on grain yield of four triticale genotypes (three promising lines of ET-82-8, ET-82-15 and ET-79-17 along with the conventional Junillo-92...
