Morphological characteristics of Freesia hybrida Klatt.

Freesia hybrida Klatt. is a perennial bulbous herb flower. The bulbs are narrowly ovoid or ovoid, with a thin film coating on the coating, with net patterns and dark red spots on the coating. The leaf is sword-shaped or strip-shaped, slightly curved, 15-40 cm long, 0.5-1.4 cm wide, yellow-green, with obvious midrib.

Freesia hybrida Klatt. The flower stem is upright, with 2 to 3 curved branches on the upper part and several leaves on the lower part; the flowers are sessile; each flower has 2 membranous bracts at the base, and the bracts are broadly ovate or ovoid, top Slightly concave or 2-pointed, 0.6 to 1 cm long and 8 mm wide; flowers are upright, light yellow or yellow-green, scented, 2 to 3 cm in diameter; perianth tube is flared, about 4 cm in length, and about 1 in diameter Centimeters, the base becomes thinner, the perianth lobes are arranged in 6, 2 rounds, the outer perianth lobes are oval or elliptical, 1.8 to 2 cm long and 6 mm wide, the inner one is slightly shorter and narrower than the outer perianth lobes.The capsule is nearly ovoid, and the dorsal cavity is dehiscent. Flowering preiod is from April to May, fruiting from June to September.

The habitat of Freesia hybrida Klatt.

Freesia hybrida Klatt. is native to southern Africa. Open-air cultivation is common in southern China, and potted plants are common in northern China. 

Growth habits of Freesia hybrida Klatt.

Freesia hybrida Klatt. likes a cool, humid environment with sufficient light, and has poor cold tolerance. The suitable temperature for growth is 15℃～20℃, and the minimum temperature for overwintering is 3℃～5℃. The large temperature difference between day and night is conducive to growth and development. The temperature at night should be 10℃～15℃, and it should not exceed 20℃ during the day, otherwise the growth will be poor. Prefers loose soil with good drainage and rich in humus.

During the growth of freesia hybrida Klatt., the bulb can promote rooting and germination at 13.5℃～15℃. Differentiation requires a low temperature of 8℃～13℃. During the flower bud development period, the suitable temperature is 13℃～18℃. If the temperature is lower than 18℃, the flowering period will be delayed and the flower stem will be shortened. Higher temperatures can promote early flowering, but plant growth is weak.

Freesia hybrida Klatt. is beneficial to promote flower bud differentiation under short-day conditions. After the flower buds differentiate, the long-day light can bloom earlier. Usually the bulbs are sown in September, and the flower buds begin to differentiate in early November, and the differentiation is completed in late November. After the plant arrives in May of the following year, the leaves gradually wither and the bulb enters a natural dormancy period.

Freesia hybrida Klatt. breeding method

The propagation method of Freesia hybrida Klatt. is divided into sowing and split-ball propagation.

sowing

Cut flower varieties can be propagated by seeds. Collect seeds in time after the seeds mature from May to June. Otherwise, the capsules will crack, the seeds will be lost, and the seeds have no dormancy habit, so they can be sowed immediately after harvest. The optimum temperature for Freesia hybrida Klatt. seed germination is 15-20 ℃, and it will germinate neatly under dark conditions for about 21 days. When the seedlings have 5 to 7 leaves, the above ground is withered and the underground bulb enters a high temperature dormancy period. After dormancy, planting and cultivating seed balls for 1 year can be used as flowering cue balls.

Using containers to raise seedlings can get flowering balls in one year. The specific method is: after the seeds are harvested from May to June, they will be sown in the greenhouse. After the seedlings emerge, they will be cultivated in the greenhouse. Keep the room temperature at 15～18℃. Give Freesia hybrida Klatt. good water and fertilizer. Until May to June of the following year, the ball diameter It can reach more than 1 cm and can be used directly as flowering bulbs.

Split ball

Generally 4 to 6 child balls of Freesia hybrida Klatt. can be born around the cue ball, which is dug up during the summer dormancy period, and the child balls are separated from the cue ball and stored, and sowed in autumn. As cut flower cultivation bulbs, bulbs with a stem circumference of 8 cm or more are required to ensure the quality of cut flowers. The method of cultivating seed balls is to dig up and store the seed balls during the dormant period in summer: by early August, the seed balls can be planted in pots. The soil can be 30% decomposed organic fertilizer, and then the cultivated soil can be put into the pot. , Then plant the ball in a pot, and cover the ball with 1 to 1.5 cm of soil. After planting, it should be watered thoroughly, and it will germinate and grow after 10 days, and will develop into bulbs in May of the second year.
