Changes of nucleic acids of wheat seedlings under spaceflight conditions

The effects of space flight on the growth of wheat seedlings and their nucleic acid content were studied. It was shown that both space and ground seedlings have almost the same appearance, dry weight and nucleic acid content in the root, coleoptile and leaves. The only difference found is in the RNA and DNA content, which is twice as much in the ground seedling apices as in the space-grown seedlings

Introduction of Neottia nidus-avis (L.) Rich. into culture in vitro

Callus cultures from ovary and ovule of Neottia nidus-avis (L.) Rich. were obtained. Dependence of callus genesis on growth regulators composition of nutrient medium it was shown. Cytomorphological analysis of callus cultures demonstrat their high morphogenetic potential

The role of first Ukrainian Universities in the development of physiological investigation of plant growth and movement

Information about contribution at scientists of first Ukrainian Universities into development of plant physiology and biochemistry is presented. Special attention is paid to studies of plant growth and movement as a basis for formation of Kholodny-Went phytohormonal tropisms theory
