Abstract

The character of an arrangement of the hairs on seeds of fi ve cotton cultivars has been investigated. Unknown feature has been found in the processes of the cells-hairs appearance from the epidermis of ovule-seed. It is shown that from the beginning of certain moment of cotton ovule development, two closely located adjoining epidermis cells, which just have come out of mitotic process, are more often simultaneously differentiated into the hairs. Arising cells-hairs form various geometrical fi gures on a surface of а ovule epidermis: lines, arches, circles. The process of differentiation into pairs is simultaneously characteristic not only for the epidermal cells, which initiate hair appearance, but also for the cells which form stomatа on the ovule epidermis.
