Transpiration activity of leaves in buckwheat varieties of different breeding periods

Abstract

Genotypic aspects of leaf transpiration intensity manifestation in 22 buckwheat varieties from different periods of creation were studied in the field in real time on intact plants. It is shown that their ability to evaporate water has a high hereditary conditionality and plays an important role in increasing photosynthetic activity and crop productivity in the breeding process. Based on this, it is concluded that when creating new varieties, it is very important not only to carry out current control over the state of this process, but also to carry out targeted selection on it, considering photosynthesis activity. In this case, it is necessary to select forms that combine high intensity of leaf photosynthesis with moderate transpiration activity.
