“…Thus it indicated the importance of harvesting the crop and quickly drying the wheat grains when it attain at physiological maturity. Similar pattern of spike dry matter accumulation in wheat was also found by Hasan et al (2007) (Table 4). In water deficit stress, plant suffers from physical drought and consequently the reduction in plant height was observed.…”

Abstract AbstractFour wheat genotypes (BARI Gom 25, E 28, BAW 1170, BAW1140) were grown under well water and water deficit stress condition to evaluate the sensitivity of physiological traits of wheat resulting reduced grain yield under water deficit stress. Wheat genotypes showed greater stability of flag leaf chlorophyll, greater ability to retain water in leaf, higher level of proline in flag leaf and kernel, higher level of soluble sugar in flag leaf and greater ability to keep the canopy cooler compared to sensitive genotype under water deficit condition. Greater spike dry matter accumulation at peak, longer grain growth duration, better yield components such as spikes m -2 and grains spike -1 under water deficit stress contributed to better tolerance of BARI Gom 25, E 28 and BAW 1170. The order of tolerance based on grain yield was BAW

“…Proline content (μ moles/g/fresh weight) was determined according to the method of (Bates, et al, 1973), and expressed on a fresh weight basis from the standard curve, using standard L-Proline according to the previous method developed (Hasan, et al, 2007). However, the Proline content was determined from a standard curve and calculated on a fresh weight basis as follows : µmoles Proline/g of fresh plant material = [(µg Proline/ml × ml toluene)/115.5 µg/µmoles / (g sample/5)] as reported by Ahmed and Hasan (2011).…”

to appraisal the genetic variations, growth, yield and yield components between ten wheat (Triticuma estivum L.) cultivars from Egypt and Yemen [five Egyptian cultivars namely;Sakha93 (E1), Giza 168 (E2), Gemmeiza 9 (E3), Shakha94 (E4), Egypt1 (E5),and fiveYemeni cultivars namely; Behoth14 (Y1), Sonalica (Y2), Acsadgahran (Y3), Kaaalhakl (Y4) and Local wheat (Y5)]. Egyptian wheats grain was provided by Agronomy Department, Agriculture Research Center, Giza, Egypt while Yemeni wheats grain from Agricultural Researches Extinction authority (The Regional Agricultural Researches for Central Highland, Yemen).All the tested cultivars were evaluated experimentally under different salt conditions i.e. 50, 100 and 150 mMol NaCl in addition to control treatment the following aspects were detected i.e. seedling length (cm), root length (cm), leaves number/seedling, number of roots/seedling and chlorophyll content (mg/m 2). At the same time, November 15 th , the wheat cultivars were planted in field in randomized complete block design (RCBD) with four replications in both seasons to measure plant height (cm), tillers number/plant, spike lets number/spike, grains number/spike, 1000-grain weight (g), grain yield kg/fed., straw yield kg/fed., biological yield kg/fed., harvest index (HI %) and grain protein %. After 50% of tasseling flowers Yemeni wheat cultivars were used as donor for pollen grains and hybridization was done in one way to calculate the heterosis (H%) for twenty-five hybrids. The obtained results showed high significant variations were observed between the tested cultivars and the highest mean values of heterosis were recorded and it can be suggested that the current wheat cultivars could be used in breeding program in the future.

“…Under high temperature, free proline is involved in osmotic adjustment to protect pollen and plant enzymes from heat injury, and also provides a source of nitrogen and other metabolites (VERSLUES and SHARMA 2010). Accumulation of proline has been shown to occur under heat stress in arabidopsis (WEI-TAO et al 2011), cotton (RONDE et al 2001) and wheat (HASAN et al 2007), and genotypic variation in proline accumulation have been reported for these species. Under high temperature certain heat shock genes are triggered, resulting in the synthesis of heat shock proteins, whereas other soluble and insoluble proteins have also been shown to exhibit changes in abundance under high temperature stress (SIMMONDS 1995, HE et al 2005.…”

-The effect of high temperature stress on six wheat cultivars exposed to 35-40 °C for 3 h each day for fi ve consecutive days was examined. High temperature significantly affected total proline, soluble protein content, membrane stability index (MSI), yield, and various yield components, and had a direct effect on growth and other physiological attributes of wheat at anthesis and the milky seed stages. The wheat cultivar AS-2002 achieved better osmotic adjustment by accumulating more leaf proline. Higher MSI was also observed in AS-2002, as well as Inqalab-91. The anthesis growth stage was found to be more sensitive to heat stress than seed development at the milky stage. Overall heat stress reduced yield 75% at anthesis and 40% at the milky stage. AS-2002 performed better on the basis of yield and yield components. Seed weight per spike was highest in AS-2002, and lowest in SH-2002. The cumulative response of AS-2002 was better on the basis of physiological and yield attributes. In addition to yield, plant breeders should also include proline and MSI as selection parameter in the breeding program for development of heat tolerant wheat cultivars. Most of the evaluated wheat cultivars/lines were developed for cultivation in the rainfed areas of Pakistan.
