Kosar %J Modern Phytomorphology %D 2012 %I Modern Phytomorphology %X The similarity of the anatomical structure of the axis of annual shoots of Pterostyrax hispida (Sieb. et Zucc.) and P. c o r y m b o s a (Sieb. et Zucc.) has established. One of the possible reasons for high winter hardiness of these plants in the introduction is a thick layer of cuticle, sclerenchyma on the periphery of the stem, and intense lignifications of histological elements of bark, wood and perymedulyar zone. %K Pterostyrax %K anatomy %K annual shoots %U http://phytomorphology.org/PDF/MP2/02269270.pdf
