Correlation of the chaenomeles productivity with some abiothic factors of the environment

Abstract

The correlations between productivity, beginning of flowering and the degree of flowering of two model chaenomeles genotypes with minimum, maximum temperature and relative humidity of air at different stages of crop formation under conditions of the Southern Coast of the Crimea were studied. The correlation analysis found out that the chaenomeles productivity directly depended on the degree of generative buds formation and the start of flowering. The strongest influence on the chaenomeles yield was provided by the maximal air temperature during the ripening periods (r = 0.7) and growth of the fruits (r = 0.69), the degree of flowering (r = 0.67-0.68), the minimum temperature (r = -0.68) and the minimum relative air humidity (r = -0.61) during the flowering period, the maximum air temperature during the of generative buds formation (r = 0.62).
