EVALUATION OF MORPHOLOGICAL PARAMETERS OF FLOWERING BUDS AND FLOWERING ON ASIMINA TRILOBA (L.) DUNAL IN THE CONTEXT OF CLIMATE CHANGE IN ROMANIA

摘要

In the context of climate change in Romania, we proposed to study the improvement of the country's flora by introducing an ornamental and beneficial species of temperate climate. Studies undertaken in spring 2017 indicate that Asimina triloba (L.) Dunal flowers under conditions in Romania similar to those in the area of origin. Thus, we found that the beginning of vegetation in flowering buds took place in the first tenth of April and continued in stages until the start of the third trimester of April, when the flowering bud dimensions were over 15 mm in diameter, while the entire period of flowing took place from 24.04-20.05. One influence on the start of vegetation in flowing buds was the average daytime temperature recorded in the planting zone of Asimina triloba (L.) Dunal studied, which compared with historical averages was twice as high.
