Sheet surface of varieties of spring tritical in the conditions of the Vladimir region

Бесплатный доступ

The article presents the results of studying the area of the leaf surface of varieties of early ripening varieties of spring triticale in the soil and climatic conditions of the Vladimir region. Differences in the dynamics of changes in the trait at the main stages of ontogenesis are revealed: tillering; exit to a tube; bloom. Ecologically stable varieties were identified that stably form a large area of the photosynthetic apparatus in different moisture years. These are, as a rule, mid-season and mid-late varieties. A high direct correlation dependence of their productivity on the total leaf surface area of plants (r = 0.72 ± 0.12), as well as plant productivity on the flag leaf area (r = 0.64 ± 0.16), was established.
