Digital Scanning of Woody Plant Growth and Development
Journal Title: Lesnoy Zhurnal (Russian Forestry Journal) - Year 2022, Vol 15, Issue 6
Abstract
The paper presents a photometric device and a procedure for quickly recording the characteristics of organs or parts of woody plants during their growth in the field conditions with maximum detail and accuracy. The procedure was tested in the study of seasonal dynamics of Viburnum lantana L. introduced in Middle Taiga and a species of local flora V. opulus L. The research results show that there are differences in the species seasonal dynamics rhythm associated with the influence of the current and previous environmental conditions. Air temperature explains the greatest dependence of the beginning of growth and the majority of phenodates. It was found that early beginning and end of vegetation is typical for V. opulus. The growth and development of the introduced V. lantana occur in a warmer environment. Shoots of V. opulus begin to grow on May 18–21, after 11 days growth is observed in V. lantana. The earliest terms of shoot growth cessation were found in V. opulus (June 19); V. lantana shoot growth ends 7 days later. The longest shoots of the current year (101 mm) were formed in V. lantana, which is 26 mm longer than in V. opulus. The beginning of shoots growth in V. opulus is observed at +4.7 °C average daily air temperature and the sum of positive temperatures 187 °C, in V. lantana this process begins at +8.8 °C and 308 °C, respectively, and the species requires 6 days with average daily temperature above +10 °C to start growing. Thus, the studied Viburnum species can be conditionally divided into 2 groups: early (V. opulus) and late (V. lantana) beginning and ending seasonal development. Cultivated in the taiga zone V. lantana belongs to the highly promising introduced species, so it can be recommended for introduction into cultural cenoses and landscaping of settlements in the taiga zone.
