The influence of abiotic factors on mass one hundred grains of the barley sort in the Kansk forest-steppe

The aim of the research is to identify decadal influence of abiotic factors of vegetation period on 1000 grains mass of barley hull-less varieties and bare-grained different ripeness in the forest-steppe of Krasnoyarsk region. Research methods i.e. breaking ground and observations were carried out in accordance with the methodology of the State variety testing in 2002-2014. Experiments were made in fourfold recurrence; an area of the plots was 25 m 2. The influence of weather conditions on the mass of 1000 grains was determined using the method of correlation analysis on the methodology of D.W. Snedekor using the statistical program package by O.D. Sorokin. We identified a strong positive relationship between the degree of weighing 1000 grains and the amount in temperature during the first decade of June, second decade of July and the second decade of August. The correlation coefficient in the first decade of June from varieties have 0.620 Omsk hull-less 2, Kedr varieties 0,723; in the decade of July 2 from 0,624 (Omsk 95) to 0,730 (Vladuk); during the week of August 2 from 0,640 (Kedr and Tatum) to 0.693 (Wiebke). Strong positive degree of connection between the mass of 1000 grains and the amount of rainfall was marked in the second decade of May, third decade of June, the decade since July, 1. The correlation coefficient was from 0,626 (Vladuk) to 0,672 (Omsk hull-less 2) - second decade of May; from 0,631 (Olenyok) to 0,727 (Buyan) - third decade of June; from 0,632 (Arat) to 0,798 (Omsk hull-less 2) - first decade in July. Also it was noted that there was a strong positive relationship between the mass of 1000 grains and the hydro-thermal coefficient in the second decade in May, ten days of June and the first decade of July. The correlation coefficient in May samples was from 0,628 (Wiebke) to 0,660 (Tatum); in the decade in June, from 0,625 (Wiebke) to 0,738 (Buyan); in the decade of July, 1 from 0,626 (Tatum) to 0,771 (Omsk hull-less 2). Conclusions: the mass of 1000 grains is increased by increasing the amount of temperature in the first decade of June, the second decade of July and the second decade of August. When the amount of rainfall increases in the second decade in May, June, decade since July, 1; with the increase of hydrothermal coefficient in the second decade in May, the third decade in June and the first decade of July.
