“…Although rice plants can withstand certain heat stress, most reports provide direct evidence of decreased rice yield and grain quality because of the increased temperature . The negative effects on rice plant caused by high temperature were a result of decreased spikelet fertility, faster grain filling, fewer filled grains, and lower grain weight, which affect grain yield and quality during the grain filling stage (Prasad et al, 2006;Mohammed and Tarpley, 2009b;Lin et al, 2010;Fahad et al, 2016). Rice grains ripened under high temperature exhibited low weights, chalky appearance, and low amylose content (Yamakawa et al, 2007;Mitsui et al, 2013).…”

High temperature negatively impacts rice production, and the heat-tolerant cultivars could improve the resistance to high temperature stress. In the present study, six rice varieties were exposed to high temperatures stress (35°C and 38°C) for 3 days during the early filling stage. The differences among two high-temperature treatments were analyzed in terms of yield components, grain quality and physiological parameters of rice. The results showed that high temperature decreased seed setting rate, 1000-grain weight, plumpness, single plant yield, brown rice rate, milled rice rate and amylose content while increased unfilled grain rate of all rice varieties compared with the control. However, the yield components of different rice varieties in response to high temperature exhibited significant genotypic differences. In addition, the influence of high temperature on the hybrid rice variety Jinyou402 was greater than that on Ganxin203, and the influence of high temperature on the conventional rice variety E134 was greater than that on Zhong531. The 38°C treatment was more damaging to early rice than the 35°C treatment. Meanwhile, the influences of high temperature on the physiological parameters of flag leaves were consistent with the influence on yield components and grain quality.

Vegetables are essential for human health and well-being. For sustaining an excellent production of vegetable crops, the seed is a primary input. Moreover, good quality seed is an important requirement for the vegetable industry, and there is a huge demand that has been expanding, considering the fact that seed multiplication is economically pertinent for vegetable cultivars to contend commercially. But the healthy seed production is usually a sumptuous trait and tormented by agricultural tactics, genetics as well as by the environmental factors. Features like seed output of the vegetables, sizeable genetic variation, the prerequisite for advancement and acceptance of a good quality vegetable seed. Here different mechanisms for seed production in vegetable crops has been presented, also vital areas and factors influencing seed production, and eventually discourses regarding the opportunity of plant breeding to sustainably make improvements to vegetable seed production.Agronomy -Climate Change and Food Security 2 flowers [4]. There are two main types of pollination, namely, self and cross-pollination. Self-pollination refers to the deposition of pollen from the anther on the stigma located on the same plant (geitonogamy). It is the closest form of inbreeding which leads to homozygosity. Species having this type of pollination develop homozygous balance and do not exhibit significant inbreeding depression [5].Whereas the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual is called cross-pollination. It is the form of outbreeding which leads to heterozygosity. Outbreeder species develop heterozygous balance and exhibit significant inbreeding depression on selfing. In addition to these two types of pollination, there is one a different kind of pollination, often called cross-pollination, where cross-pollination often exceeds 5% and may reach 30%. Various mechanisms such as bisexuality, homogamy, cleistogamy and position of anthers promote self-pollination, whereas other mechanisms such as dicliny (namely monoecy and dioecy), dichogamy, heterostyly, herkogamy, selfincompatibility (namely sporophytic and gametophytic) and male sterility promote cross-pollination [6].Nearly one-third of the current global population is suffering from some form of malnutrition. Moreover, with a constant rise in the world population the food demand tends to increase up to 60% [7]. Vegetables being shorter duration crops can play a crucial role in providing more food per unit of cultivated area [8]. Similarly, climate change is a result of human activities primarily related to the emission of greenhouse gases. It means that there must be a focus on vegetable production and lowering the per capita emissions of greenhouse gases [9]. Vegetables are sensitive to temperature fluctuations, and environmental stresses have also been found to affect the nutrient composition of vegetables [10].Monoecious, that is, cucurbits have both male and female flowers on different branches of the same pla...

Представлено результати досліджень впливу триазолпохідного ретарданту фолікуру на морфогенез, накопичення неструктурних вуглеводів, ключових елементів мінерального живлення та врожайність культури аґрусу. Обробка рослин аґрусу сорту Машенька 0,025 %-м розчином фолікуру у фазі бутонізації позитивно впливала на формування мезоструктури листків: збільшувалася товщина хлоренхіми та листкової пластинки в цілому, зростали лінійні розміри й об’єм клітин стовпчастої та губчастої паренхіми, відбувалося накопичення хлорофілів. За дії препарату в листках та пагонах відкладалося більше неструктурних вуглеводів й елементів мінерального живлення, ніж у контролі. Такі зміни забезпечували необхідний резерв вуглеводів та елементів живлення для формування й росту плодів і приводили до суттєвого підвищення врожайності культури.
