Альтернативний метод визначення посухостійкості ріпака озимого на ранніх етапах його розвитку

Abstract

Results of the studies about the drought-resistance of winter-annual "00" and "+0" types of the rape collection on solutions of saccharose with an osmolality of 10, 14, 16 atmospheres are presented. It is estrablished that the larger drought-resistance of "00" sorts is formed under the conditions of the south-east.  It is discovered that between the intensity of the roots growth under the control with the intensity of the roots growth with the saccharose solutions there is a mild negative relation (with r = - 0,18 ± 0,19 to r = - 0,28 ± 0,12) with the germination of seed on saccharose solutions – substantial positive relation (with r = 0,63 ± 0,15 to r = 0,28 ± 0,19)
