Abstract:

Autumn daffodil is one of wonderful ornamental bulbous of Amaryllidaceae family from Iran which grows wildly in the north and west of the country. This species has many potentials as an ornamental plant for its attractive yellow golden flowers and the bright color of the leaves. In this research, the effect of 5, 15 and 25°C temperatures, as well as short (8 hours), neutral (12 hours) and long (16 hours) day lengths on vegetative and reproductive growth as a factorial based on completely randomized design with 9 treatments and 5 replications (each replication a pot with two bulbs) was investigated. After applying the mentioned temperatures for 30 days on its bulbs in summer and their cultivation and after the sprouting, day length was applied. The results of this research showed that in the 15°C with neutral day length and 5°C with long day length, the highest and lowest fresh and dry weight of leaves was obtained, respectively. The temperature of 5°C delayed the sprouting time of bulb and 15°C accelerated it, also the temperature of 5°C with short day length decreased the percentage of bulb sprouting. Treatments of 15 and 5°C with short day lengths accelerated and delayed flowering, respectively. The temperature of 25°C with a neutral day length increased the percentage of flowering. Generally, according to the obtained results, the treatment of 15°Cwith a neutral day length recommended for the growth and flowering of this plant
