Morphological Characteristics Of Reed

  Morphological characteristics of reed

  Perennial, rhizome is well developed. Stems erect, high 1-3 (8) m, 1-4 cm in diamonds, with more than 20 knots, base and upper internodes shorter, longest internodes between lower 4-6, long 20-25 (40 ) Cm, under the section was wax powder. Leaf blade lower than the lower part of the upper part, longer than its internodes; leaf tongue edge of a circle about 1 mm long short hair, both sides of the hair length of 3-5 mm, easy to fall off; leaf blade lancet linear, 30 cm long , 2 cm wide, glabrous, apically long acuminate. Panicle large, 20-40 cm long, 10 cm wide, branched majority, 5-20 cm long, densely submerged spikelets; spikelet length 2-4 mm, glabrous; spikelets ca. 12 Mm, with 4 flowers; winged with 3 veins, first glume 4 mm; the second glume ca. 7 mm; the first incandescent lemma male, ca. 12 mm, the second lemma is 11 mm long, with 3 veins , The tip of the long acuminate, the base plate extension, both sides of the dense and so long in the lemma filamentous pilose, and hairless spikelets connected with a significant joint, mature easily after the joint off; Mm, two ridge rough; stamens 3, anthers 1.5-2 mm long, yellow; caryopsis ca. 1.5 mm. Chromosome 2n = 36 (Tischler 1942, Labadie 1976a) 44,46,48 (Hunter 1934, Vachova 1976), 49,50,51,52,54 (Avdolov 1928,1931), 84 (Tarnavschi 1948), 96 (Gorenflot et al. 197). For high polyploid and aneuploid plants.

  Reed was born in the rivers and lakes, pond ditch along the coast and low wetlands. Widely distributed for the world. In addition to the forest habitat is not growing, a variety of open areas of water, often with its rapid expansion of reproductive capacity, the formation of contiguous reed community.

  leaf

  Leaves articulate, leaf blade long or lanceolate, arranged in two rows. Leaves 15-45 cm long, 1-3.5 cm wide.

  Summer and flowering, panicles, terminal, evacuated, mostly white, panicle branches densely, oblique extension, inflorescence length 10 a 40cm, slightly drooping, spikelets with 4 to 7 flowers, male and female, inflorescence length 15 to 25 cm, spikelets long 1.4 cm, white or brown, inflorescence at the bottom of the spike is male, the rest are male and female flowers, flowering from 8 to 12 months.

  fruit

  Reeds of the fruit for the caryopsis, lanceolate, the top has persistent style. Long, stout creeping rhizomes, mainly to rhizome reproduction, reed is often seen in the water plants or dry ponds, reeds and Hanmang often mixed, the difference is that the reed stems are hollow, and cold Mans is not, in addition, Hanmang everywhere can be seen, reed is bunk water and students.
