Correlation dependence of the biometric indices of cabbage color from the conditions of the growing season

Abstract

It was established that the height of plants of cauliflower flowers by 37% depended on the features of the hybrid and 50% of the conditions of the growing season. The aggregate effect of the factors was 3%, the share of other factors was 10%. The phase of formation of the head in height exceeded the plants of hybrids Livingstone F1 (control) and Opal F1 at 6.8-15.6%, respectively. The analysis of the correlation connection revealed a strong direct dependence of the linear height of the cabbage plants of the flowering and GTK during the growing season: r = 0.94 ... 0.99. The Cool F1 hybrid is less responsive to this factor than other hybrids. The average daily air temperature and the amount of active temperatures during the growing season are also factors affecting the biometric indices of plants. There was a strong direct correlation between the linear height of cabbage plants and the sum of active temperatures above 10 oC. At the same time, the correlation coefficient ranged from 0.92 in the Lyndington F1 hybrid to 0.99 in the Kul F1 hybrid. Average daily air temperature also exerted a strong influence on the height of plants of cauliflower flowers: r = 0,89 ... 0,99. The number of leaves on plants of cabbage of color on the 8% depended on the features of the hybrid and 61% of the conditions of the growing season. The combined effect of the AB factors was 4%, while the share of other factors was 28%. Correlation analysis shows that in the number of leaves the hybrids of the cabbage of the colored flower responded almost identically to the weather conditions of the growing season: r = 0,94 ... 0,99. In this case, a smaller correlation coefficient is noted in the Livingstone F1 hybrid. The average daily air temperature and the sum of active temperatures had the same effect on the number of leaves of cauliflower flowers, regardless of the hybrid: r = 0,99 The diameter of the socket of cabbage leaflets has a significant influence on the average daily temperature, GTK and rainfall during the growing season.
