ASPECTS OF GROWTH AND DEVELOPMENT OF RUBIA TINCTORUM L. PLANT IN MEDIUM SALTY SOILS OF MIRZACHOL

Abstract

The article provides information on the growth and development aspects of the R. tinctorum L. plant in the moderately saline soils of Mirzachol. In moderately saline Mirzachol soils, root germination (100%) and preservation (68.0%) were found to be high in the 1st growing year. After a one-month natural dormancy period, the laboratory germination rate of seeds was 3%. After a three-month dormancy period, seed germination increased to 6%. In our study, the effect of stratification on R. tinctorum seed germination was identified. The results show that stratification of R. tinctorum seeds has a positive effect on seed germination.
