“…Amylose and amylopectin contents were also determined as per the standard procedure already used (Goher and Akmal, 2021). Briefly, a 12.5 mg sample was taken in tubes, added with 5 mL (45%) perchloric acid, and dissolved completely.…”

“…Primarily yield is assumed from grain weight and number on a column. Wheat spike is the primary yielddetermining trait and its length and weight express the final product (Goher and Akmal, 2021). Spike length and weight are, therefore, the most significant traits affecting yield.…”

“…Some unexpected rainfall in March adversely affected pollination and hence a decrease in the average grain set per spike was noted (Khan and Akmal, 2021). Some areas receive unwanted rains close to the crop maturity and hence caused lodging problems for mechanical harvesting (Goher and Akmal, 2021). However, it is generally observed that temperature rise is the main cause of changing rainfall patterns and distribution .…”

“…Limited HS when coinciding with the very sensitive stage of plant growth may adversely affect yield and/or grain quality (Asseng et al, 2015). Adverse effects have been observed on grain yield and its quality when plants are exposed to heat shocks at the grain development stage (Goher and Akmal, 2021). It might be expected that high temperature ensures food security in some parts of the world (Prakash et al, 2017).…”

“…The plant experienced temperatures over 24 o C and has shown a significant decrease in grain yield (Prasad and Djanaguiraman, 2014). The grain protein content is also adversely affected by plants facing high temperatures at the reproductive stage of growth (Goher and Akmal, 2021). Leaf N interrelates with grain protein (Iqbal et al, 2017).…”

The transitional phase of climate change is becoming a threat worldwide. Fluctuations in temperature are frequently observed in the life cycles of field crops. The current study was intended to evaluate heat stress (HS) at sensitive stages on four wheat cultivars’ growth, grain yield, and quality traits during two consecutive seasons. The experiment included four spring wheat cultivars that were exposed to HS durations (i.e., 0, 48, 96 and 144 h) at booting and anthesis stages. Pots were kept in an open-air, and labeled pots were moved to the glasshouse at the respective growth stage. After HS treatments, pots were moved from the glasshouse to the original position in the open air. The results showed that the cultivars differed in yield and grain quality traits, but their collective mean effect was significantly expressed with HS and HS duration (HSd) on the measured traits. Spike length was significantly affected by HS at the anthesis in comparison to those obtained from the control. However, the increase in HSd did not cause a significant effect on spike length compared to other treatments. Spike weight was significantly decreased in plants exposed to HS at booting and anthesis as well as by increasing HSd. In addition, grain weight and numbers were decreased in plants exposed to HS at booting and anthesis stages with a similar pattern by increasing HSd. Moreover, a reduction in amylose content was observed in grains of plants exposed to HS at booting and anthesis stages or when plants as exposed to a longer period of HSd. Nonetheless, amylopectin, wet gluten (WG) and grain N (GN) showed an increase in plants exposed to HS at booting and anthesis stages and/or extending HSd. This study concludes that plants exposed to different HS treatments during the life cycle had lower values for spike length, grains weight, and grains number per spike including amylose content in comparison to those obtained from the control. The decrease was significantly noted in the yield and grain quality of wheat when plants were exposed to HS at the booting stage in comparison to those exposed to HS at anthesis.

Explaining the physiological and ecological effects of wheat population density can provide new research methods for field crop production. A three-year field trial under drill single-seed seeding was conducted, which used three different intra-row seed-seedling spacings to quantitatively analyze the density effect from three perspectives—population, individual plant, and single-stem panicle—at the winter wheat harvest. The results showed that year and density had significant effects on both the population and individual plant yield (p < 0.05), as well as on some yield components and biomass indicators. The interaction between planting density and annual climate was found only in the number of grains for both the entire population and individual plants. With the increase in planting density, the CI gradually increased, inhibiting the growth of individual plants and leading to a negative impact on monoculture wheat yield. The drill single-seed seeding method can provide a basic experiment condition for analyzing the density effect. The density effect of wheat populations originates from intraspecific competition, which mainly affects the growth of individual plants. Research based on the analysis of density effects from the perspectives of population, individual plants, and single-stem panicles can provide a methodological reference for precision agriculture.
