“…The superiority of the second date (Nov 10 th ) in the number of grains and gave the highest value (26.17) grain spike -1 compared with the fourth date, which gave the lowest number of grain (24.75) grain spike -1 (Table 4), The reason for the superiority of the second date is due to the appropriate temperature during the emergence and development stage of the spike, which led to the increase of the development period of the growth apical in the spikes and the reduction in the rates of abortion of the florets and spike during the emergence phase of the spike. This is due to the superiority of this date in the growth characteristics, which provided a vegetation cover that intercepts the light sun and encourages the increase of photosynthesis and the dry matter formed and associated with the formation of a vegetative group ability of intercepting the light to perform photosynthesis (Girish et al 2018) This finding agreed with Chaudhary et al (2017).…”

A field experiment was carried out during the winter season 2020-2021 in the AL-Sufia area, east of Ramadi, to estimate effect of spraying cytokinin on the growth and yield of barley (Hordeum vulgare L.). By using the split plot plate arrangement by randomized complete block design (RCBD) with three replications, the study included two factors, the first factor, three concentrations of cytokinin 0 (K1), 30 (K2) and 60 (K3) mg L-1. taken and sprayed on the vegetative part in equal parts for two sprays, each spraying 0, 15 and 30 mg L-1 when the first vegetative branch appeared. The second factor is the planting dates and they were Oct 25th , Nov 10th, Nov 25th and Dec 10th, and the symbols (D1, D2, D3, D4) were taken. Concentration of 60 mg L-1 of cytokinin significantly affected the yield characteristics and its components, as this concentration recorded the highest average in the characteristics number of grains in the spike, weight of 1000 grains, and grain yield was 26.20 grains in the spike-1 and 53.77 g. and 5.633 ton H-1 respectively. The planting dates also had a significant effect on the yield characteristics and its components, second date superior Nov 10th in most of the studied traits, and the yield traits recorded the highest rates in the trait of the number of spikes 402.7 spikes m-2 and number of grains spike 26.17 grain spike-1, and grain yield amounted to 6.198 ton h-1

Barley is described to mostly use sucrose for night carbon requirements. To understand how the transient carbon is accumulated and utilized in response to cold, barley plants were grown in a combination of cold days and/or nights. Both daytime and night cold reduced growth. Sucrose was the main carbohydrate supplying growth at night, representing 50-60% of the carbon consumed. Under warm days and nights, starch was the second contributor with 26% and malate the third with 15%. Under cold nights, the contribution of starch was severely reduced, due to an inhibition of its synthesis, including under warm days, and malate was the second contributor to C requirements with 24-28% of the total amount of carbon consumed. We propose that malate plays a critical role as an alternative carbon source to sucrose and starch in barley. Hexoses, malate, and sucrose mobilization and starch accumulation were affected in barley elf3 clock mutants, suggesting a clock regulation of their metabolism, without affecting growth and photosynthesis however. Altogether, our data suggest that the mobilization of sucrose and malate and/or barley growth machinery are sensitive to cold.
