Air humidity indicated as vapour pressure deficit (VPD) is directly related to transpiration and stomatal function of plants. We studied the effects of VPD and nitrogen (N) supply on leaf metabolites, plant growth, and mineral nutrition with young micropropagated silver birches (Betula pendula Roth.) in a growth chamber experiment. Plants that were grown under low VPD for 26 d had higher biomas...
Abstract This work focuses on the achievements of Polish researchers in field vegetative reproduction plants under vitro conditions. For more than 50 years, micropropagation methods have been used Poland whenever is necessary. Most perennial horticultural crops, such as fruit plants, majority ornamental geophytes, and some vegetables (e.g., rhubarb horseradish), require clonal owing to their hi...
We compared the growth of trees produced by micropropagation from nodal stem sections or callus tissue of a 20-year-old silver birch (Betula pendula Roth) tree with that of seedlings; growth was monitored for 17 months in pots followed by six years in the field. Micropropagated trees from both nodal stem sections and callus tissue grew at a similar rate to seedling trees and no obvious mutant t...
