The spectral characteristics of the tissue seedlings of rye

An in vivo cytophotometric method was used to study the spectral characteristics of coleoptile tissue and a leaf of two-day seedlings of winter rye. The optical density of axial transmittance of light in the visible region of the spectrum by parenchyma and tissues of conducting beams in seedlings grown in light and in complete darkness was estimated. It was revealed that under conditions of etiolation all the studied tissues had minimal average values of optical density in the visible part of the spectrum as compared to those during germination under illumination conditions.

MORPHOLOGICAL ASPECTS OF LEAF DEVELOPMENT IN WINTER RYE SHOOT

As objects of research were used plants of winter rye at the time of flowering samples collected from nursery trials control scientific research Institute of agriculture of the South-East: district grade – Talovskaya 41, Radon, Snezana, Bezenchukskaya 87, Memory Kunakbaeva, Chulpan 7, Roxana; Saratov (scientific research Institute of agriculture of the South-East) – Elishaevskaj, Volzhanka, Saratov 7, Marusen’ka, Memory Babicheva, Sunshine. The length of the leaf blade and vagina and the leaf blade area were determined.
