[Callose content in cell walls of leaf epidermis and mesophyll in Alisma plantago-aquatica L. plants growing in different conditions of water supply].

The relative callose content in Alisma plantago-aquatica leaves has been studied at the phases of budding and flowering--fruiting. The callose content in cell walls was shown to vary depending on the type of tissue, phase of ontogenesis and of water supply.

Clinorotation [correction of Clinoratation] effects on the structural-functional response in potato minitubers.

It is established that high plant growth and development in microgravity occurred normal. However, the change of plant growth rate is accompanied by the change of carbohydrate metabolism in photosynthesized cells (Kordyum, 1997). The decrease of starch grain size in chloroplasts and the decrease of content cellulose in cell wall were revealed (Sytnik et al.
