Abstratct Brazilian Cherry tree is a native fruit tree belonging to the Myrtaceae family, with ample adaptation to the different edaphoclimatic conditions of Brazil, which makes this fruit widely known. However, there are still few commercial orchards, which may soon be reversed, since studies have shown the benefits of the consumption of this fruit for human health, as well as the potentialities for industrial processing. Thus, Brazilian Cherry tree will no longer be a backyard plant and will be grown in commercial orchards, which demands the production of seedlings with genetic quality. Sexual propagation with the use of seeds should be replaced by asexual propagation by means of cutting, grafting, spreading and tissue culture. The grafting method has proven to be efficient in more than 70% of cases and herbaceous cuttings have rooting greater than 77%. New studies on micropropagation and better control of herbaceous cutting processes should stimulate and economically increase the commercial production of this fruit for fresh consumption or processing. This review article included the results of other studies, addressing advances, limitations and protocols for propagation of Brazilian Cherry tree.

Abstract The Myrtaceae family has representatives spread worldwide, and Jabuticaba tree is an important species native to Brazil, which is grown not only in the backyards and domestic orchards, but also in commercial orchards, landscaping projects and in several tropical and subtropical countries. The propagation of this species in a sexual form or by seeds is simple and efficient, being able to reach 100%. However, long juvenile phase and genetic segregation have led to the search for methods that allow the propagation of selected trees and guarantee through their standardized and productive clones, fruit quality and fruiting precocity. Protocols for asexual propagation are still scarce, but they show efficient methods, making possible the commercial use and valorization of this Brazilian fruit tree. Grafting methods have proven to be efficient in more than 70% of cases. Herbaceous cutting in Jabuticaba trees shows rooting around 10%. Air layering shows rooting rates above 80%. Other methods considered for domestic use have shown satisfactory results in the formation of young saplings through woody cuttings. New studies on micropropagation and better control of herbaceous stem cutting processes could stimulate and economically increase the propagation of this fruit tree for commercial crops to produce fruits for fresh consumption or processing. Air layering and grafting are the most currently indicated methods for propagation of jabuticaba tree. This review paper shows the results of other papers and their protocols for obtaining jabuticaba tree seedlings and clonal plants.

Abstract This review aims to present advances in studies on the propagation of the Annonaceae species, which includes species of economic importance such as: soursop, custard apple, atemoya and cherimoya. In sexual propagation, advances are mainly related to a better understanding of the stages of seed development, dormancy mechanisms, and germination. In asexual propagation, compatibility studies between grafts and rootstocks are presented, focusing on the expression of genes involved in tissue formation. The cutting method is also discussed, which is another option for the propagation for this group of plants considered difficult to root, approaching endogenous and exogenous factors related to the subject, as well as management strategies that affect the success of this technique.

Salixplanifolia Pursh ssp. planifolia and Salixmonticola Bebb are the dominant willow species of Colorado Rocky Mountain willow carrs. Extensive field observations suggest that neither of these species is capable of sexual propagation under continuous sedge cover on peat soils. Growth experiments using willow stem cuttings in pots of saturated peat soil indicate that S. planifolia produces more root biomass (p = 0.0031) and shoot biomass (p = 0.0001) than S. monticola during one summer of growth. Male 5. planifolia and female S. monticola produce more dry-weight root (p = 0.0390) and shoot (p = 0.0442) biomass than their conspecific opposite sex. A species by sex by elevation interaction is significant for root biomass (p = 0.0360). The results are suggestive that these taxa have different regeneration niches. Asexual propagation driven by beaver activity is suggested as an explanation for the dominance of s. planifolia in mires and how this species colonizes vegetated peat soils. Beaver cut and store willow stems for a winter food source. This activity provides willow fragments for asexual colonization of mires.

The propagation of plant is required for the purpose of the multiplication of new plants. The producers want desired character of plant and for that purpose they need true to type plants. The true to type plants can’t be produce by the sexual reproduction. The different types of clonal propagation methods can be used for the producing true to type plants Clone means plants which are the exact copy of the individual parents by asexual propagation. Clonal propagation can be used as a method of the production of the genetically identical copies of the individual parent. The clones are required for the purpose of producing identical plants as sexually propagated plants have different variations which can affect the yield, quality and the other characters. To avoid these variations asexual methods are promoted for the propagation of genetically identical new plant such as cutting, layering, tissue culture etc. Many researchers have carried out the work to develop new and different techniques for the sole purpose of clonal propagation of plant.

Natural disasters may adversely affect coastal resources potentially leading to coastal habitat restorations that incorporate stakeholders and the general public. Appropriate methodologies for habitat restoration are developed to ensure the outcomes of this project. Currently, seagrass bed restoration by means of asexual and sexual propagation techniques have been used worldwide. However, the experience of seagrass (Enhalus acoroides) habitat restoration in Trang Province noted that to accomplish this project’s strategies involved the application of restoration techniques along with public and stakeholder participation. The application of asexual propagation, specifically the collection of single shoots from donor seagrasses and subsequent transplantation, is a convenient tool. However, from this project results, this process still has conceptual problems as from the large numbers of single shoots collected from donor seagrasses, the survival rate was relatively low. Furthermore, this process was complicated by conflicting interests between local communities near to the donor site and the project’s organizers. In order to reduce said conflicts, other techniques to balance stakeholder interests were instigated by this project, namely the development of both asexual and sexual propagation techniques. This project initiated a sexual propagation technique by the collection of wild seeds of Enhalus acoroides that were subsequently grown in the laboratory before natural habitat transplantation. This project results showed that seeds can be grown rapidly and can be cultured in large numbers. However, this development technique has a limit on rearing time because seedlings were found to be in decline after the third month of the experiment. These problems were compounded by a limiting factor that pushed the project’s organizers to decide to transplant seagrasses from the laboratory to the wild whether a time was seasonally suitable or unsuitable, the planting activity still done forward. This matter may have enhanced the low survival rate situation after seagrass transplantation to the wild. If there is a need to recover a seagrass bed, the above culture and transplantation methodologies should be used in conjunction with repeated periodic plantings until natural ecological function has been restored. In conclusion, further research should be instigated to improve the cultivation method for producing ready to plant seedlings and to improve methods of project operation.

Abstract It is thought that plant propagation, i.e. multiplying plants, preserving their qualities, and tending them, began approx. 10,000 years ago when people began to cultivate plants for food and other products (Hartman et al., 2010). Most basic methods of plant propagation had been discovered before the start of recorded history, and many plant species had already been domesticated (selected and adapted to human use), including cereals and legumes (Hartman et al., 2010). The two main types of plant propagation are sexual and asexual propagation. Sexual propagation usually involves the production of seed, leading to production of progeny with variable characteristics, so it is often used in plant breeding. Asexual propagation leads to clones of the parent plant and is useful when specific characteristics are desired in the new plants. There are many different forms of asexual or vegetative propagation, including cuttings, grafting, division, storage organs and in vitro techniques.

SUMMARYSelection for high and low growth-rate was carried out during eight generations of asexual propagation by zoospores and seven generations of sexual reproduction by oospores. The fungus has previously been shown to be diploid during its vegetative phase. In the zoospore lines there was no significant variation and no response to selection, except for the occasional appearance of fast-growing sectors. A high line was established from such a sector; in its sexual progeny the inheritance of growth-rate was non-Mendelian. Propagation through self-fertilized oospores released very considerable genetic variation, and both high and low lines responded to selection. At first the variation within families, and the response to selection, increased with succeeding generations, despite the intense inbreeding. In later generations the high line became less variable, and the progeny oospore cultures resembled the fast-growing sectors. It is concluded that growth-rate is controlled by a polygenic system and by cytoplasmic determinants, a mutant form of which is responsible for the fast-sectoring phenotype.

Vacinium fruits are genetically heterozygous species characterized as “not coming true from seed”. Conventional methods for vegetative propagation of these species, although successful, are slow and labour-intensive, and few propagules can be produced from one plant of a selected clone or hybrid. Micropropagation techniques are important for clonal multiplication, germplasm im provement and gene conservation of Vaccinium fruits cultivated in Canada including blueberries, cranberries and lingonberries. In vitro propagation of these species using axillary bud proliferation and adventitious shoot regeneration has been investigated in a number of studies. Morphogenesis seems to be highly dependent on plant growth regulators and media used for culture, and this dependence is genotype specific. The paper presents the progress in-depth of various aspects of the in vitro culture of Canadian Vaccinium species for their commercial production. Also discussed are techniques for clone rejuvenation and plant tissue culture for mass propagation of Canadian Vaccinium nuclear stocks. Key words: Blueberry, cranberry, lingonberry, micropropagation, regeneration, morphology
