Non technical summary soybean yield is very sensitive to elevated temperatures global temperatures are predicted to increase and these changes in temperature conditions have the potential to considerably decrease soybean yields. High-temperature stress (or heat stress) is a serious constraint to the productivity of grain legumes as their cultivation is expanding to warmer environments and temperature variability is increasing due to climate change large genetic variations exist in grain legumes for heat tolerance which can be exploited for the development of locally.
This host mediation of high-temperature tolerance in aphids should be taken into account when modeling population dynamics under the influence of global warming, host adaptation, and the risk analysis of alien pest invasions. High temperature (28ºc) showed reduction of mn toxicity in both soybean cultivars the cultivar biloxi always showed at all temperatures greater concentration of mn than forrest the cultivar biloxi always showed at all temperatures greater concentration of mn than forrest. Differ in their tolerance to high temperature (karanja and wood, 1988) it has been reported that the effect of root temperature on nodulation and nitrogen fixation in legumes can be modified by the strain of rhizobium or the host species and cultivars within the species (gibson, 1967 day et al, 1978) the ability of rhizobia and bradyrhizobia to.
Raising temperature from 29/20 to 34/20 o c during seed fill decreased soybean seed yield ( dornobos and mullen, 1991) sapra and anaele (1991) reported that soybean cultivars differ in their sensitivity to high temperatures. Soybean germination begins with the seed imbibing (absorbing) approximately 50% of its weight in water followed by the development of the radicle (primary root) and emergence of the cotyledons (seed leaves. 2011 integrated crop management conference - iowa state university — 93 corn and soybean response to soil ph level and liming antonio p mallarino, professor, agronomy, iowa state university agustin pagani, graduate. Soybean temperature tolerance as a crop, soybeans are even more encumbered by changes in temperatures than other alternatives particular the impact of heat and drought its ongoing preferred temperate growth results in it losing its nitrogen fixation capabilities under high temperatures but, let’s get right into a discussion on heat. The key requirement for assessing frost damage to either corn or soybean is to be patient and allow the plants to show you whether they are capable of recovering while corn and soybean leaves may blacken and wither within a day after frost occurs, the true extent of plant damage may not yet be discernible.
Physiological mechanisms for high salt tolerance in wild soybean (glycine soja) from yellow river delta, china: photosynthesis, osmotic regulation, ion flux and antioxidant capacity. Often lethally, by high temperature (ht) stress [2,3] heat stress causes multifarious, and often adverse, alterations in plant growth, development, physiological processes, and yield [4,5] (figure 1) one of the major consequences of ht stress is the. 论文编号: 论文题目: differences in the high？temperature tolerance of aphis craccivora (hemiptera: aphididae) on cotton and soybean: implications for ecological niche switching among hosts. The identified high temperature-tolerant genotypes andtemperature-dependent pollen response functionsmight be useful in soybean breeding and.
Effect of high temperature on ripening in rice plants: analysis of the effects of high night and high day temperatures applied to the panicle and other parts of the plant japanese journal of crop science 73, 77 – 83 [in japanese with english summary. Qtl study to reveal soybean response on abiotic and biotic stresses puji lestari, sutrisno, and i made tasma indonesian center for agricultural biotechnology and genetic resources research and development, jl tentara pelajar 3a, bogor 16111. Impacts of extreme heat stress and increased soil temperature on plant growth and development june 21, 2016. Screening soybean genotypes for high temperature tolerance by in vitro pollen germination, pollen tube length, reproductive efficiency and seed yield published | 2018 in indian journal of plant physiology. High temperature tolerance in chickpea and its implications for plant improvement v improvement of chickpea tolerance to high temperature key words: genetic variation, legumes, pollen, semi-arid tropics, tolerance 1 introduction chickpea is a major grain legume used for food from ancient days it is one of the essential semi-arid tropical.
Flooding tolerant soybean germplasm the open agriculture journal, 2010, volume 4 39 because current us soybean cultivars have a narrow genetic base [11-12], soybeans with better flooding tolerance. Project methods in previous research, an exotic plant introduction line was identified with tolerance to high temperature stress during germination. Managing soil ph in the optimal range is essential to producing high-yielding and profitable soybeans the first step to managing soil ph is.
This review describes the status of chickpea production, the effects of high temperature on chickpea, and the opportunities for genetic improvement of chickpea tolerance to high temperatures keywords: genetic variation, legumes, pollen, semi-arid tropics, tolerance. High to low drought tolerance the crop yield model proved to be an efﬁcient tool for identifying drought the crop yield model proved to be an efﬁcient tool for identifying drought tolerance of brazilian soybean cultivars and for choosing the best cultivar for a given environment.
Missouri soybean merchandising council endowed professor of genetics and soybean biotechnology, division of plant sciences, university of missouri-columbia, 2002-present paul whitfield horn distinguished professor of genetics, texas tech university and texas a&m university system, 1997-2002. Soil temperature the ideal temperature for soybean germination is 77 o f and the optimum range is 68 to 86 o f the maximum is 94 o f, where temperature will actually inhibit germination planting early (mid-april to mid-may) may delay emergence due to cool soils planting in july increases risk of high soil temperatures, but soil moisture. Background high-temperature stress inhibited the growth of cucumber seedlings foliar spraying of 10 mmol − 1 exogenous spermidine (spd) to the sensitive cucumber cultivar ‘jinchun no 2’ grown at high-temperature (42 °c/32 °c) in an artificial climate box improved the high-temperature tolerance.
