Influence of the short-time heat shock on the behaviour of the antioxidant enzymes in winter rye seedlings (Secale cereale L.). pp. 16--22
Summary: Seedlings of winter rye on the stage of first true leaf on the short-time heat shock have stronger reacted then seedlings on earlier stage. This was expressed in changes of activity of such antioxidant enzymes as ascorbate peroxidase, guaiacol peroxidase, catalase and superoxide dismutase. Seedlings of winter rye on coleoptile development the stage integrally didn't react on the short-time heat shock, but decrease the activity of guaiacol peroxidase and catalase in chloroplasts indicated on stress sensitivity of these organelles in any plant age.

The effect of epibrassinolide on growth, development and productivity of regenerant hafts of meristeme potato plants (Solanum tuberosum L.). pp. 23--26
Summary: Influence of epibrassinolide onto synthesis photosynthetic pigments and productivity of potato plants of Lazurit sort grown from graft regenerants of meristemic plants at ion-exchange substrate using ionitoponic technology has been stated. It has been shown that epibrassinolide at 10-5%/ha concentration leads to reduction of total mass of a tubers yield of one plant by 11--15% and reduction of reproductive coefficient by 32% of regenerants out of apical grafts.
It has been supposed that the effects are connected with existence of phytogormones gradient in a stalk of the parent plant that causes metabolism changes in graft regenerants of various anatomic origins.

Pattern of variation and correlation between diploid potato meiotic abnormalities "tripolar spindles", "irregular AII" and "fused spindles". pp. 41--45
Summary: The second meiotic division abnormalities "irregular (irr) and tripolar (tps) chromosome segregations" in interspecies hybrids of diploid potato were studied. The results obtained shown these abnormalities are genetically conditioned modifications of the phenomenon "fused spindles" (fs). The frequency of irr and tps varied among genotypes studied, fraction of random effects was great in their variation (at about 50%). The results obtained allow the suggestion that irr and tps are controlled by polygenes, which modify expression of main genes controlling fs. Diploid potato clones with the meiotic abnormalities fs, irr and tps presents are of great interest for further genetic and cytological investigations of the structure and positioning mechanisms of division poles in plants with acentrosomic spindles.

Stimulative action of kinetin on activity of antioxidative systems of green barley leaves (Hordeum vulgare L.). pp. 54--57
Summary: The levels of total and reduced ascorbate as well as the activity of ascorbate peroxidase and content of superoxide dis-mutase in green barley leaves treated with kinetin were studied. It was shown that kinetin effects on these parameters depended on the duration of kinetin treatment and was more pronounced in 7-days age leaves after spraying for three times to during 3 days. In such condition the contents of total and reduced ascorbare increased on 20 and 60% in comparison with the control, respectively. The activity of ascorbate peroxidase and content of superoxide dismutase increased on 7% and in 2 times compared with the control, respectively. The data obtained indicate that kinetin treatment results in increase of activity of antioxidative systems of plants. It is proposed these plants will be more tolerant to stress conditions.
