The lily flower consists of six basic parts:

1. pedicel (pedicel), branching attribute,

2. receptacle (receptacle), branching attribute

3. calyx (calyx), leafing attribute

4. corolla (corolla), leafing attribute

5. pistil group ( gynoecium), leaf attributes; the anatomical drawings are as follows:

The appearance of the scales is one of the bases for the classification of species. Most lilies have lanceolate, unarticulated scales, and the scales are mostly arranged in compound tiles on the bulb disk to form a bulb. The surface of the stem is usually green, or mottled with brown, or brownish-red throughout. Stems usually terete, glabrous. Leaves are arranged in a spiral loose arrangement, rarely whorled. Leaf shape is lanceolate, rectangular-lanceolate, and oblanceolate, elliptic, or striped.

Leaves are sessile or shortly petiolate. Leaves entire or with small papillae. Flowers large solitary, clustered or in racemes. Flowers erect and pendulous or flat, often brightly colored. Tepals 6, in 2 whorls, free, often connivent and bell-shaped, trumpet-shaped. Flower color has white, yellow, pink, red and other colors. Stamens 6, filaments slender, anthers elliptic larger.

Bulbs white, 4-7 cm high, 5-8 c.c. in diameter, broadly ovate, about 10 cm deep into the soil; stems erect, hard, the basal part buried in the soil with 2-3 whorls of fibrous roots, the above-ground part is 1.2-1.5 m high, 0.8-1.2 cm in diameter, ribbed, dark purple, while covered with white woolly hairs.

Leaves scattered, sessile, glossy, lanceolate, 3-15 cm long, 0.5-1.5 cm wide, apex acuminate, with more than 5 conspicuous veins, upper leaves gradually becoming shorter to form leafy bracts, usually with bead buds in the axils of the leaves; the bead buds are globose, 2-3 mm in diameter, and turn black with age. Inflorescence racemose-conical;

Pedicel stout, spreading, flowers slightly pendulous; tepals 6, orange-red, densely purple-black speckled, reflexed when open, lanceolate, 8 centimeters long, 1.5 centimeters wide; stamens 5-7 centimeters long, anthers purple and speckled; stigma purple, ovary 1.3-1.8 centimeters long. Fruit obovate, 3 to 4 cm long. The flowering period is usually in July.

. p>Reproduction methods

(a) seed propagation

1, harvesting seeds: 10 to 15 days after the pollination of lilies, the ovary began to expand, after 60 to 150 days fruit ripening and cracking can be harvested before.

2, spring and fall can be sown. Spring sowing, the next spring, when the temperature exceeds 30 ℃ sowing. Before sowing the seeds in front of the light, picking out the embryo development of seeds for sowing, germination temperature for 12 ~ 15 ℃. 15 ℃ above the seed germination fast, but the seedling is weak; and 5 ℃ below the germination.

3, sowing soil with two parts of fertile loam, one part of coarse sand and one part of peat soil, adding 1 gram of superphosphate per cubic liter.

4, after sowing mulch 0.5 ~ 1 cm, about 20 ~ 30 days cotyledon emergence. 6 months after the flowering.

5, fall plants withered after the formation of small bulbs, cultivated 2 to 3 years after becoming a flowering bulb.

(B) scale cuttings

1, scale cuttings are not limited by season, when the bulb is old and mature dug out 3 to 4 years bulb, placed in a ventilated place to blow-dry, peeled off the fat scales.

2, wooden sand beds, shallow pots will be inserted into the scales 2/3 ~ 4/3, inserted thermal insulation and shade, after 45 ~ 120 days after the formation of small bulbs.

(C) sub-ball propagation method

1, when the stem node close to the ground grows a small sub-ball, carefully removed.

2. One plant can be propagated from each bulb.

(D) Group propagation

First clean with detergent, then sterilize with 75% alcohol and 0.1% mercuric ascension for 30 minutes, then rinse with sterile water 3 times. Larger scales can be cut into small pieces and inoculated on MS medium with the addition of naphthalene acetic acid 0.5-1.0 mg/liter and 6-benzylaminopurine 0.1-1.0 mg/liter. 5-7 days later, small spherical protrusions appeared on the explant, and 14 days later, the small spheres turned into clustered buds, and small bulbs were formed 1 month later.
