PHENOLOGY OF SOME SPECIES FROM THE GENUS OPUNTIA (TOURNEF.) MILL. (CACTACEAE JUSS.) IN CONDITIONS OF COVERED SOILSIN APSHERON

Abstract

The paper is devoted to the study of phenology and cycle of seasonal development of 25 species (Opuntia aciculate, O. anahuacensis, O. bentonii, O. camanchica, O. cardiosperma, O. dulcis, O. engelmannii, O. humifusa, O. leucotricha, O. linguiformis, O. lindheimeri, O. littoralis, O. macracantha, O. maxima, O. monacantha, O. phaeacantha, O. polyacantha, O. rastrera, O. rufida, O. stricta, O. sulphurea, O. tardospina, O. tortispina, O. undulate, O. vulgaris) from the genus Opuntia in conditions of covered soils in Absheron. Using the results obtained it is found that all the studied species from the genus Opuntia pass the full cycle of the seasonal development in the covered soil conditions in Absheron (the beginning of the formation of new segments, the phase of budding, the phase of flowering, the formation and ripening of fruits, and the end of vegetation).
