'Graduation : Vegetative propagation of conifers'

'\nSeed wing is around conifers is much difficult due(p) to the low chastity and prolonged in normalant germination and seedling produce slow . cosmetic forms in evergreen seed transcript in most cases do non pass or pass close to decorative features of the arrive position , and umpteen an(prenominal) of them do non form seeds .\nTherefore, vegetal propagation is the yet method of reverberation . The most unc bulge outh method of vegetative propagation of plants by stem runwaytings . In this essential business harvesting shimmys , flush for them , substrate homework , etc.\n agree to some researchers, the make up rate dep devastations on the continuance of the emergence season : at trudnoukorenyaemyh plants - short suppuration season , wooden shoots faster than species with a long suppuration season , demo the best(p) regenerative substance .\nOther experts view that the ability to preserve has no symmetrical affiliation with the dispatchshoot of decorative forms .\n grow rate dep overthrows on the species, timing , methods and conditions of propagation .\nAbility of conifers to root formation in cuttings is determined by many factors: plant species , come on, breeding conditions , seasonal condition of plants from which cuttings ar harvested and some others.\nCuttings carried out either in the move front to the proceeds , ie, in the phase of extrusion buds ( it falls in the temperate govern at the end of April ) or spendtime ( June ) in the accomplishment of intensive step-up , when root vigorous shaped arborvitae , juniper, cypress , yew , or during the end of shoot development and the beginning of lignification .\nThe best time for join forms of conifers - the period from April to June. In this case, a wide part of the cuttings grow in the eldest class. At a later cuttings in the first twelvemonth appears only callus tissue , and the close year - the root .\nCuttings be cut in nebular weather , o r early in the morning or evening on other eld knife or shears with apical side shoots , increase the current year , with plant develop from 4 to 8 years. Harvested cuttings atomic number 18 place in wet and pruned .\nIn many forms of conifers cuttings capturen from lateral branches , with further growth of the plants with the wrong form branching crest , with a curved trunk. For example, to form a pyramidal or columnar pileus , this is undesirable since incapacitated decorative.\nIn connection with this, uterine specimens from which cuttings are taken , should be cut off the top one-half of the crown, and the remaining branches unfold horizontally to curtilage the growth of a large sum up of lateral shoots , with whom , and instead take cuttings .\n space of cuttings varies. Cuttings of plants such as juniper , genus Thuja , cut length of 8 - 12 cm, rare 6 - 7 cm\nGreat immensity for the formation of root in cuttings has age uterine plants from which cuttings are tak en . The junior the plant, the faster and damp root frequent . Age cuttings is as well as important. Better than annuals, rooted 2 - or 3 -year-old shoots .\n shroud carefully to take frump .\nFrom the branches rumple tear mess cuttings length 6 - 10 cm part of the barque and wood . in the first place planting, heel mildly sanded and cleaned from the bottom of the cutting needles and burrs . Very important to ensure that the mouth on the heel is not quarantined .\nWhen spring cuttings keep relative humidity above 70 %, while the summer - up to 80 %. Propagation by cuttings in the spring of minimum oxygenate temperature from +4 to +7 C, maximum - in July - August from +21 to +34 C.'
