Biomorphological features of varieties <i>Canna x generalis</i> Bailey when introduced under arid conditions

The article presents the results of studies of the biomorphological features of cannas in arid conditions. It was found that the varieties differ in the height of shoots and their number, the number of leaves and flowers on the shoots, the number of renewal buds formed by the end of the growing season. On one shoot of the Crozi cannas varieties, 2-4 renewal buds are laid, of which 1-2 shoots develop. All varieties are characterized by: the effect of the size of the 1st assimilating leaf on the total number of leaves is observed only on the first order shoots; an increase in the height of shoots with an increase in their order; a decrease in the number of leaves with an increase in the order of shoots; in the conditions of the Karshi oasis at an elevated air temperature (average ten-day values from +26.7 to + 33.4°С) in June-August - there is an increased growth and development of the aboveground part, with a decrease in temperature (to 19.5°С) from the end of September - underground.
