Изучена пространственная организация мезофилла хвои у 9 видов рода Pinus, относящихся к подродам Pinus и Strobus. Выделены и охарактеризованы основные пространственные формы ассимиляционных клеток на основе поперечных, тангентальных и радиальных сечений хвои. Показано, что клетки более сложных конфигураций наблюдаются в хлоренхиме мягких сосен. Выявлены различия в строении мезофилла хвои у двуххвойных и пятихвойных сосен.
The authors explored the situation in vegetation on hay harvesting areas and pastures in the mid mountain areas of Central and South-Eastern Altai in 2016-2017. The authors investigated 22 communities of various types of meadows and steppes; 8 cenoses were investigated twice. The vegetation of forage lands indicates moderate or high grazing of animals. 2016 was a wet year and it led to pasture degradation and progressive succession. 2017 was a dry year and grazing led to acute pasture degradation and reducing of surface phytomass in 2.2 – 3.6 times in comparison with the previous year. At the same time, the part of mortmass in the stand grass increases. The researchers investigated the perennial leguminous grasses of Astragalus austriacus, A. austrosibiricum, A. tibetanus, Hedysarum gmelinii, H. gmelinii subsp. setigerum and Oxytropis argentata and found out them to be preserved in grasslands and restored in many cenopopulations when grazing is reduced or stopped.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
