Abstract:
The response of two Aster cultivars to temperature and photoperiod was studied using two types of rooted cuttings, rosette shoots initiated from basal buds in short-day conditions (SD) and axillary shoots initiated from axillary buds in long-day conditions (LD). Mother plants, rooted cuttings and the resulting plants were subjected to various combinations of photoperiod and temperature, including vernalization. In general, LD (24 h of light) caused elongation, delayed branching and inhibited flowering. Flowering occurred in SD (10-12 h sunlight) on elongated shoots. In SD and low temperature (17/12°C, day/night) the rosette stage of growth was preserved. Short day and higher temperature (27/17°C, day/night) or vernalization of mother plants caused limited elongation and simultaneous branching of rosette shoots, soon followed by flowering. Axillary shoots were committed to elongate and branch immediately after planting, independent of photoperiod or vernalization. When planted in SD, transfer of branched shoots from SD to LD was followed by the production of terminal buds composed of an inflorescence or only an involucre. Plants that had originated from axillary shoots failed to develop shoots from basal buds during a second as well as during the first growth cycle. © 1992.

Control of growth and flowering in two aster cultivars as influenced by cutting type, temperature and day length
The response of two Aster cultivars to temperature and photoperiod was studied using two types of rooted cuttings, rosette shoots initiated from basal buds in short-day conditions (SD) and axillary shoots initiated from axillary buds in long-day conditions (LD). Mother plants, rooted cuttings and the resulting plants were subjected to various combinations of photoperiod and temperature, including vernalization. In general, LD (24 h of light) caused elongation, delayed branching and inhibited flowering. Flowering occurred in SD (10-12 h sunlight) on elongated shoots.
