Physiological and proteomic analysis of the response to drought stress in an inbred Korean maize line
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 ...
متن کاملstudy of drought tolerance indices in maize inbred lines under limited irrigation and normal conditions
abstract in order to genetic investigation of drought resistance indices, on 25 maize inbred lines, an experiment was conducted under three irrigation regimes; normal irrigation, limited vegetative irrigation and limited reproductive irrigation. in the limited vegetative irrigation, tol (stress tolerance) index had the highest phenotypic and genotypic coefficient of variation (83.83% and 68.04%...
متن کاملThe Effect of Trichoderma Isolates on Morpho-Physiological Changes of Polianthes tuberose Under Drought Stress Conditions
In order to evaluate the effect of different Trichoderma isolates on reducing the effects of drought stress on Polianthes tuberose flower, two factorial experiments were carried out based on a completely randomized design with three replications. In the first and second experiments, the first factors were Bi and 65 isolates of Trichoderma harzianum at three levels (0,...
متن کاملCombining ability and testcross performance of drought‐tolerant maize inbred lines under stress and non‐stress environments in Kenya
Drought and poor soil fertility are among the major abiotic stresses affecting maize productivity in sub-Saharan Africa. Maize breeding efforts at the International Maize and Wheat Improvement Center (CIMMYT) have focused on incorporating drought stress tolerance and nitrogen-use efficiency (NUE) into tropical maize germplasm. The objectives of this study were to estimate the general combining ...
متن کاملIdentification of Drought Tolerant Mechanisms in Maize Seedlings Based on Transcriptome Analysis of Recombination Inbred Lines
Zea mays is an important crop that is sensitive to drought stress, but survival rates and growth status remain strong in some drought-tolerant lines under stress conditions. Under drought conditions, many biological processes, such as photosynthesis, carbohydrate metabolism and energy metabolism, are suppressed, while little is known about how the transcripts of genes respond to drought stress ...
