effect of seed priming by salicylic acid and application of controlled water stress in flowering stage on some physiological characters such as relative water content, chlorophyll index, photosynthetic rates, transpiration rates, stomatal conductance, and leaf internal co2 concentration was investigated on cowpea (vigna unguiculata l. cv. parastoo) plants. experiment was done as a split block d...
in order to investigate the impact of foliar zn application in reducing the negative effects of water stress on bean growth and yield, a field experiment was carried out in the research field of ilam university in 2011. the experiment was arranged in split factorial based on a randomized complete block design with three replications. the experimental factors were water stress including water wi...
A two-year field experiment (2015–2016) was conducted as a split plot design with four replications at School of Agriculture, Shiraz University, Iran to investigate the influence of water stress (supplying 50, 70, and 100% of water requirement) and wheat residue rates (0, 25, and 50%) incorporated with soil on physiological traits and canned yield of sweet corn (Zea mays L. V. Saccharata). Net ...
in this regard, the morphophysiologic and anatomic characteristics of six olive cultivars (nabali, feshomi, arbequin, zard, gordal and roghani) were investigated under drought. experiments were designed based on factorial and complete block random plot with two control treatments, -1.5 mpa stress and three replicates. the investigated factors were as follows: leaf area, specific leaf area, leaf...
Drought stress is a limiting factor for production in agriculture. In order to evaluate the impact of plant growth regulators, Salicylic acid and Paclobutrazol on growth and physiological traits of Sweet Basil (Ocimum basilicum) under drought stress condition, a factorial pot experiment based on Randomized complete design with 4 replication was carried out at research greenhouse of Mohaghegh Ar...
Silicon is known to ameliorate the deleterious effects of drought on plant growth. We evaluated growth of wheat (Triticum aestivum L. CV. Chamran) under Water-Deficit Stress Induced by Polyethylene Glycol as affected by Si application. In this article, the effects of Si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (RWC), electrol...
In order to evaluate the effect of water stress on sunflower cultivars of Iroflor in different stages of growth and methods of biophosphate consumption, a factorial experiment was conducted in a randomized complete block design with four replications. Water deficit stress in four levels including control (non-stress), stress in vegetative stage, stress in reproduction stage and stress in both v...
in order to study the effects of drought stress and nitrogen (n) levels on grain yield, yield components and water use efficiency of grain corn (sc.704), a field experiment was conducted in 2009 growing season. the experiment was split-plot based on randomized complete block design arrangement and four replicates. main plots were three irrigation levels included optimum irrigation (i1), moderat...
The effects of different water stress (control, medium, and severe) on some morphological, physiological, and biochemical characteristics and bud success of M9 apple and MA quince rootstocks were determined. The results showed that water stress significantly affected most morphological, physiological, and biochemical characteristics as well as budding success on the both rootstocks. The increas...
Common waterhemp is one of the most commonly encountered and troublesome weeds in the midwestern United States. It is well known that water stress adversely affects crop growth and yield; however, the effects of water stress on weed growth and seed production are poorly understood. The objective of this study was to determine the effects of degree and duration of water stress on growth, develop...
