“…In their method, efficient rhizome multiplication was achieved on an MS medium supplemented with 2.0 mg L −1 BAP and 0.5 mg L −1 NAA. In the Polish cultivar 'Juanita, ' Podwyszyńska et al (2000) reported enhanced root formation aer adding paclobutrazol (0.1 mg L −1 ) to NAA containing medium. Furthermore, pretreatment of the in vitro rhizome cultures at 20 °C and 16-hr photoperiod for 10 days, prior to a low-temperature treatment, resulted in superior rooting in vitro, better plant survival in a greenhouse, and positively influenced flowering.…”

This work focuses on the achievements of Polish researchers in the field of vegetative reproduction of plants under in vitro conditions. For more than 50 years, micropropagation methods have been used in Poland whenever vegetative reproduction is necessary. Most perennial horticultural crops, such as fruit plants, the majority of ornamental geophytes, and some vegetables (e.g., rhubarb and horseradish), require clonal reproduction owing to their high heterozygosity, i.e., their offsprings when reproduced from seeds, do not repeat the parental characteristics. Various goals have been pursued in the development of regenerative and in vitro propagation systems for each of the aforementioned groups of plants, such as pathogen elimination, reproduction of healthy plants, rapid multiplication of newly obtained valuable breeding lines and cultivars, and breeding to obtain polyploids, haploids, and doubled haploids. Owing to the growing interest of researchers and plant producers in environmentally friendly technologies, one of the sections is devoted to the issue of biotization of micropropagated plants.

To study the temperature requirements for flowering, cuttings of A. baileyana were either transferred between different temperatures in controlled-environment growth cabinets, kept outside or in a shadehouse. Plants in the growth cabinets were transferred from a low (13/9˚C) to high (23/19˚C) temperature, from a high to low temperature, or kept at a constant intermediate (18/13˚C) temperature, and then transferred outside. Acacia baileyana required temperatures at or above a mean maximum of 18˚C and a minimum of 13˚C for bud formation, and at or below a mean maximum of 16˚C and a minimum of 9˚C for flowering. Nearly twice the number of plants transferred from high to low temperature flowered compared with outside plants. Bud formation was inhibited at a temperature of 13˚C maximum and 9˚C minimum. Large buds dropped when the temperature was above 18˚C maximum and 13˚C minimum, indicating that the timing of plant transfer between the warm and cool conditions should be when the buds are at a medium size. Light intensity also affected flowering, with less than half the number of plants flowering in the shadehouse compared with outside. Plants transferred from high to low temperature were induced to flower 4 months earlier than outside plants by manipulating the temperature. Flowering cut stems or pot plants of A. baileyana could be produced for Mother’s Day in May and for other key markets.
