| Abstract:
Many cuttings of tropical foliage plants are shipped from the tropics to Florida for propagation. The effect of storage temperature and duration is not known. Cuttings of P. oxycardium, grown in the tropics, were obtained Monday mornings at four week intervals for one year. Fifty cuttings were planted immediately into Vergro potting medium on a mist bench. Additional cuttings were used for storage and temperature studies, and stored at 10, 13, 16, or 19°C for 4, 8, or 12 days. Twenty-three days after placement on a mist bench, cuttings were examined for number of roots, total root length, and shoot length. Forty rooted cuttings were taken from each treatment and potted 4/10 cm pot containing Vergro. Seventy-two days later, total fresh weight of new growth was recorded. Results were inconsistent, but tests indicated that healthy cuttings can be stored for as long as 12 days at cool temperatures (10 – 19°C) without serious detrimental effects. | |
