Zinnia graceful, Zinnia elegans. Description, illustrations of the plant Zinnia graceful, Zinnia elegans. Botanical description of the plant, areas of growth and ecology, economic importance, applications Zinnia graceful is an annual herbaceous plant, a species of the genus Zinnia (Zinnia) of the Asteraceae family. Zinnia graceful, along with hybrid petunia, is one of the most popular flower crops; is one of the ten most common flyers around the world. In the USA, it is the most famous among the zinnia species, it is especially popular and is considered the national flower. Zinnia graceful is an annual herbaceous plant. At home, this species grows up to 1 m in height, has simple white, pink and orange inflorescences. The stem is straight, 30-120 cm high, mostly not branched (except for undersized dwarf varieties), rounded in cross section, green or purple-greenish outside, densely pubescent with large, hard, simple colorless hairs. The shoots of the first order significantly outgrow the main one, so that in the future it becomes almost invisible after flowering. All shoots end in an inflorescence - a basket. Some variety groups form a large number of flowering shoots of the second and third orders, while others have fewer. Leaves opposite, sessile, amplexicaul, oblong-ovate, entire, with 3-5 almost parallel veins, shortly pointed or obtuse at the apex, 5-7 cm long and 3-4,5 cm wide. The leaf surface is rough from densely covering it with hard hairs. The hairs are simple, of two types: the first are small, densely covering the leaf blade, the second are larger, sparse, saber-curved, hard, pressed to the leaf surface. The upper leaves are smaller and longer pointed. The flower-bearing stem under the basket is thickened. The bed of the basket is blunt-conical, protruding especially at the end of flowering, with keeled navicular scales. Inflorescences - baskets, 5-16 cm in diameter, simple, semi-double or double. The flowers in the inflorescence are tubular and reed. Non-double inflorescences have one row of reed flowers, semi-double - from two to five rows of reed flowers, double - more rows. The doubleness of inflorescences in zinnia is false, it is not associated with the transformation of generative organs into petals, but depends only on the number of reed flowers in the inflorescence. In addition, the inflorescences of one plant do not always have the same number of rows of reed flowers. With prolonged drought, terry falls The involucre of modified apical leaves is cup-shaped, tiled. Involucre leaflets arranged in several rows, grassy, oblong-oval in shape, 0,6 to 1,3 cm long, obtuse with a dark border in the upper part. In reed flowers, the corolla is interpetalous, consists of one plate - a tongue with three teeth at the end. Flowers unisexual - female. The tongues are elongated-oval, up to 4 cm long, up to 1,5 cm wide, their size decreases from the periphery to the center. Ovary inferior of two carpels, unilocular. Marginal flowers are false-lingual, of various colors, except for blue and blue, sometimes with a white or yellow border around the edge. Tubular flowers are small, bisexual, proterandric, consist of 5 fused petals about 1,2 cm long, 0,4-0,6 cm wide, with 5 small teeth along the edge. The flower has 5 stamens, the filaments are free; anthers fused into anther tube surrounding style. The anthers open with a longitudinal slit into the cavity of the tube, where all the pollen spills out. The pistil has a style with a two-lobed stigma. At the ends of the lobes there is pubescence in the form of a brush (striking hairs). During the ripening period, the lobes diverge and the stigmas become capable of receiving pollen. Disk flowers are tubular, yellow, orange, rarely purple. Pollen is two-celled, rounded. Known genes that cause male sterility, which is used to obtain seeds of heterotic hybrids without castration. The first such hybrid was obtained in 1960. To date, a large number of heterotic hybrids have been created, which are triploids obtained from crossing tetraploids with diploids. Natural crossing of zinnia graceful with other types of zinnia is not observed, however, such hybrids were obtained indirectly. In particular, using embryo culture technology, a hybrid of Zinnia peruviana L. x Zinnia elegans Jacq. was created, in which, under normal conditions, the endosperm degenerates a week after fertilization, and the embryo dies from lack of nutrition. Blossoms in June - August, possibly also until frost. Seeds ripen approximately two months after the start of flowering, however, depending on the variety, the duration of the seed ripening period is different. Zinnia is a cross-pollinated plant, the norm of spatial isolation is at least 200 meters Seeds are large, 8-14 mm long and 2-6 mm wide, strongly flattened. Their shape is very diverse - from narrow wedge-shaped to broad-ovate. The surface of the achene is rough, covered with tubercles, on its underside there is a keeled rib. Coloring - dark gray, brownish or brown. The number of chromosomes in somatic cells is 2n = 24. The species is distributed in southern Mexico. It grows on rocky ledges of canyons, at an altitude of 1500 m above sea level.
