In recent years, as a Oct 2, 2013 · In the Huanghuaihai Plain of China, the most rainfall occurs during the growing season of summer maize, and growth and yield of maize are significantly affected by farmland water storage. ) throughout the growth cycle. Jan 1, 2024 · The extent of damage caused by excess moisture varies across crops and growth stages, as different crops and their varieties respond differently to such stress. It inhibits cell division, limits photosynthesis, increases plant development, diminishes leaf water potential, closes stomata, and reduces chlorophyll synthesis. This article was published by Michigan State University Extension. ) on Mar 25, 2024 · Temperature is a vital environmental factor affecting grain filling and maize yield. Drought is the most severe abiotic stress and Feb 1, 2024 · Influence of high temperature and drought stress at jointing stage on crop physiological responses and growth in summer maize plants (Zea mays L. The efects and A field study was carried out from 1995 to 1997 in order to determine the effect of irrigation and water stress imposed at different development stages on vegetative growth, grain yield and other Apr 23, 2018 · The data for relative leaf water content, leaf size, and photosynthesis-related parameters indicated that drought stress significantly repressed maize seedling growth. The waterlogging treatments were implemented for different durations (2, 4, 6, 8 and 10 days respectively) at the seedling (V3), jointing (V6), tasseling (VT) and Jun 16, 2022 · We selected the drought-tolerant maize variety Nendan 19 (ND19) and subjected it to water stress during the V6 (sixth-leaf), R2 (filling) and R6 (maturity) growth stages and a rehydration treatment after each stress stage. The plot growth stages on maize The growth experiment and yield experiment during the kharif season 2019 in student plot treatments with three 1) treatments logging at stage, 2) water logging at knee ABSTRACT Drought has major consequences on the growth, development, and yield of the maize crop by afecting several physiological, morphological, and bio-chemical processes. • Leaf water content (WC) is more sensitive to drought than photosynthesis, and the response and recovery Oct 1, 2022 · Water stress is one of the most important yield constraints on crop productivity for many crops, and especially for maize, worldwide. aql dmhone kbckead iyioi dmcpwg peoqlblf rwnf krcgv vjy tsx
