The plastid machinery of apical meristematic cells of potato tubers whose growth is regulated by melaphene

A comparative ultramorphometric study of the plastid machinery of apical meristematic cells of potato ( Solanum tuberosum L.) tubers in a normal state (during sprouting) and under treatment with melaphene, a growth regulator of a new generation, at a growth-stimulating concentration was performed. The area of the plastid machinery of cells was found to increase under the effect of melaphene. A stimulatory effect of melaphene on starch accumulation and development of peripheral plastid reticulum in leucoplasts of apical meristematic cells of potato tubers was discovered.
