“…In this manner, the grains serve as a source of dry matter production and the vegetative plant parts as a sink for dry matter accumulation. These findings supported the results of Singh and Dwivedi [6], Mishra et al [15] and Sanghera and Thind [16].…”

A field experiment was conducted during Rabi season (2015-16) at Instructional Farm, Department of Agronomy, College of Agriculture Junagadh Agricultural University, Junagadh (India) to evaluate the identification of suitable date of sowing and variety of wheat (Triticum aestivum L.) for South Saurashtra (Gujarat). The **), test weight (r=0.995**), experiment was laid out in split plot design with four dates of sowing in main plots (05th November, 15th November, 25th November and 05th December) and three varieties in sub plots (GW 322, GW 366 and GW 173) and replicated thrice. The analysis showed positive correlation between grain yield and growth parameters viz, plant height at 60 DAS (r=0.932**) and harvest (r=0.940**), dry matter accumulation at harvest (r=0.976**), crop growth rate between 30 to 60 DAS (r=0.996**), root dry weight at 60 DAS (r=0.945**) and harvest (r=0.867*), root length at 60 DAS (r=0.960**) and harvest (r=0.935**). Grain yield showed positive correlation with yield attributes and nutrient content viz, effective tillers/plant (r=0.758**), spike length (r=0.937**), grains/spike (r=0.991**), spike weight (r=0.954water use efficiency (r=0.785**), N content (r=0.884**), P content (r=0.918**) and K content in grain (r=0.873*).

“…Several phonological stages are manifested throughout its development, high temperature could affect SGR directly by affecting seed metabolism or by affecting the supply of assimilate to the seeds (Egli, 1998). Total dry matter accumulation was adversely affected by heat stress and reduces the dry matter production (Nicolas et al, 1984;Sanghera and Thind 2014). Dry matter accumulation and cell division proceeded at a higher rate but had a shorter duration of the high temperature treatments (Nicolas et al, 1984).…”

Seven wheat varieties were cultivated during the winter seasons of 2013 and 2014 in Sulaimani Crop Research Center-Bakrajo. A Field experiment was conducted each year as CRBD with three replications.The most important vegetative and reproductive criteria were studied as well as dry matter accumulation and its partitioing through destructive samples. They were taken every 10 days in order to study the partitioning of assimilates to different parts of the plant leaf, stem, and spike under different environmental factors of the two years.The influence of the duration length of seed filling on the accumulated dry matter and its partitioning to the spike, the Spike Partitioning Coefficient and growth parameters such as Seed Growth Rate (SGR) and Seed Filling Duration (SFD)were studied. Environmental factors were influenced the Dry matter accumulation and the partitioning of assimilates as well as the length of the growth stages especially SFD.

“…The heat stress at the flowering and grain-filling period of wheat damages the structure and function of chloroplasts in wheat leaves and hinders chlorophyll (Chl) biosynthesis, reducing Chl content and photosynthetic rate and accelerating leaf senescence (Feng et al 2014, Liu et al 2017. Dry matter accumulation and partitioning to grains are important factors sensitive to heat stress that affect wheat yield (Álvaro et al 2008, Sanghera andThind 2014).…”
