Abstract

The effects of different periods of storage at low temperature on some plant parameters were examined at anthesis. The duration of the low-temperature storage affected the time taken for plants to reach anthesis, the stem lengths and shoot dry weights. However, flower size and dry weight scarcely altered with the duration of treatment. Despite large differences in the dry weights of the plant components at anthesis following different periods of low-temperature storage, the ratio of total plant dry weight at anthesis to the initial bulb dry weight at the commencement of treatment remained almost constant. Anthesis occurred in all treatments when the total plant dry weight fell to 70% of the original bulb mass. It is possible to relate flower quality to the fresh to dry weight ratio of the flower.
