[The effect of biologically active substances from coniferous plants on the L-phenylalanine ammonia lyase and peroxidase activities in wheat leaves].

The effect of the preparations produced from needles and wood of various coniferous species on the activities of L-phenylalanine ammonia lyase (PAL; EC 4.3.1.

Inheritance of the light intensity response in spring cultivars of common wheat.

The effects of low/high light intensities and day length on ear emergence time in climatic chambers were studied in 12 common wheat (Triticum aestivum L.) cultivars of different ecogeographical origin. Low light intensity (LI) affected the time to ear emergence in all the wheat cultivars of both the photoperiod sensitive and insensitive genotypes, increasing the number of days to ear emergence (DEE).

[Genetic diversity of reaction of common wheat (Triticum aestivum L.) cultivars to light intensity].

The effect of low light intensity (LI) on the period from sprouting to earing was studied in 12 cultivars of the spring common wheat under controlled conditions. Differences between cultivars with respect to their responses to LI (RLIs) were found both for those that were photoperiod-sensitive and those that were almost photoperiod-neutral. Specifically, a prolonged photoperiod and a low LI differently increased the period from sprouting to earling in different cultivars.

[Isolation and in vitro translation of polysomes and the RNA matrix from gibberellic acid-treated etiolated dwarf pea shoots].

The effect of gibberellic acid (GA) on the size of polysomes (PS) and on the specific translation activity of epicotyl PS of two dwarf pea varieties was studied. It was shown that GA does not significantly alter the specific translation activity of PS and of mRNA isolated from dwarf pea epicotyl PS. Electrophoretic separation of the polypeptides synthesized in a cell-free protein-synthesizing system in PS of control and GA-treated shoots revealed no differences between them.

[Effect of gibberellic acid on RNA synthesis in dwarf peas].

The effect of gibberellic acid (GA) on total RNA and polysomal poly-[A]+-RNA synthesis in epicotylia and embryos of dwarf pea of two varieties differing in their physiological sensitivity to GA was studied. It was found that incubation with GA increases the accumulation of total RNA in pea epicotylia, var. "Pioner" and "Polzunok".
