Physiological comparison of the diploid and tetraploid sugar beet on the early stage characters shown by water culture.

Abstract

In the present paper dealt with the gical comparison of the dipioid and tetraploid sugar bee.t on the early stage characters shown by water culture. l) The getmir, ation of tetraploid seeds was noticeably poot as compared withthat of the dipioid. 2) The growth of leaves and roots of the dip ioid seedling was more vigorous than those of the tetraploid. 3) The diploid plant surpasses the tetraploid in the yields of tops and roots as well as the number of leaves. 4) The stomata of the tetraploid are larger in size and smaller innumber compared with those of the diploid. 5) The osmotic pressure in the diploid plants was proved to be higher than that in the tetraploid ones. 6) The carbon assimilation was Inore vigorously going on in the diploid than in the tetrapioid.
