The specific in vitro conditions cause a modified structure and physiological functions of the photosynthetic apparatus which result in poor survival rate of plantlets during acclimatization.The type of vessel closure affects the gaseous composition and hence affects the growth of plantlets in culture. The aims of the present research are to find the closure material which is gas permeable and to study the effect of the improved gas exchange on the growth and the photosynthetic ability of the micropropagated apple rootstock MM 106.The improvement of gas exchange leads to rise of the content of sorbitol and the ratio sorbitol : sacharose. This might be a sign of a better carbon metabolism of in vitro cultivated apple rootstock MM 106.
