coleoptile
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.
Experimental data on influence of light of various quality on formation kernels wheat during the period embryogenesis are resulted. Linear parametres of development of separate structures kernel in various conditions of vegetation of plants are established.
