Abstract

SummaryPlantlets of the dwarfing plum rootstock cv Pixy produced in vitro grew poorly after growth was checked when they were potted after transfer from the growth room to the glasshouse, or when transferred from the glasshouse to the field. Chilling for two months at 0°C before potting, or post-potting sprays of 200 ppm GA3 were equally effective in improving growth. Plants stimulated in this way produced fewer multiple stems, and when potted and treated in early spring grew sufficiently to be transplanted to the field in midsummer.
