Taxa of the Conyza section of the genus Erigeron, which have formed a secondary range in Eurasia: Erigeron canadensis, E. sumatrensis, E. bonariensis and the hybrid E. canadensis × E. sumatrensis, were studied. The material for the study was herbarium specimens (P, MPU, MA, H, C, DBN, DUB, S, UPS, PRC, PRA, LE, MW, MW, MHA, KW, MSK, MSKU) and plants from spontaneous invasive populations of different regions of Eurasia. The classical morphological method was used with the identification of stable morphological characters on the mass material collected in nature, which allow labelling the taxon. In addition to the previously analysed macromorphological characters, this paper presents the results of the study of micromorphological characters (structure of seed trichomes, features of trichomes of vegetative organs, structure of the stomatal apparatus) obtained using a digital microscope Keyence VHX-1000 and scanning electron microscope LEO 1430 VP. A table of diagnostic macro- and micromorphological characters within the Conyza section of the genus Erigeron was compiled.
Рябченко А.С., Виноградова Ю.K. Макро- и микроморфологические признаки видов Erigeron sect. Conyza (Less.) Baill. чужеродных для Евразии. Изучены таксоны секции Conyza рода Erigeron, сформировавшие вторичный ареал в Евразии: Erigeron canadensis, E. sumatrensis, E. bonariensis и гибрид E. canadensis × E. sumatrensis. Материал для исследования – гербарные образцы (P, MPU, MA, H, С, DBN, DUB, S, UPS, PRC, PRA, LE, MW, MHA, KW, MSK, MSKU) и растения из спонтанных инвазионных популяций различных регионов Евразии. Использован классический морфологический метод с выявлением на собранном в природе массовом материале устойчивых морфологических признаков, позволяющих маркировать таксон. Помимо проанализированных ранее макроморфологических признаков, в данной статье приводятся результаты исследования дополнительных микроморфологических признаков (строение кроющих трихом семянок, особенности трихом вегетативных органов, строение устьичного аппарата), полученные с применением цифрового микроскопа Keyence VHX-1000 и сканирующего электронного микроскопа LEO 1430 VP. Составлена таблица диагностических макро- и микроморфологических признаков внутри секции Conyza рода Erigeron.
