Nutrition of the micropropagated fruit trees in vitro and ex vitro
Published June 24, 2003
43-46.

Some experience or details are introduced in connection with the nutrient uptake of micropropagated fruit trees in the different phase of the in vitro or ex vitro development. It can be stated, that the plants during the micropropagation procedure are overfed. Special careful nutrient supply is necessary during the acclimatiza...tion.

Further information to the acclimatization of "in vitro" plants
Published September 13, 1999
54-58.

The experiment was carried out with in vitro propagated 'MM 106' apple-rootstock plantlets. The transpiration of the plantlets was examined, and the changes followed by SEM analysis.

Data about the transpiration intensity of the acclimatized plants, of its value under different conditions of relative humidity and influenced by ...the existence of roots, as well as by the degree of acclimatization are presented.

Leaves were also examined and it was found, that stomata of in vitro developed leaves closed slowly, and the number of stomata of newly developed leaves decreased.

It is also shown, that in vitro propagated roots, generally, lose their hairs during acclimatization, but these roots are all the same important, as new roots of full value develop out of them.
