“…Treatment means of wounding without hormone (T3) was not significantly different from wounding with hormone (T4). Other previous studies have indicated that cuttings derived from juvenile stock plants are easier to root [1,2,4,6]. This may be a factor in the observed percentage survival for all the treatments.…”

“…As tree species possess meristems that are normally perennially dormant and mature more slowly than active ones, these meristems often produce vigorous sprouts (e.g., stump sprouts) after the release of dormancy [5,11,12]. The rooting ability of juvenile cuttings has been ascribed to optimum levels of sugars and the total carbohydrate content and low nitrogen [4] The length of the longest root was not significantly affected although there were differences among the treatment means. Auxin transport has naturally been studied almost exclusively in young seedlings, where synthesis takes place in the actively proliferating tissues.…”

Stem tip cuttings of Khaya anthoteca seedlings were experimented for the trapping of Arbuscular Mycorrhizae Fungi (AMF). This study aimed to determine the effect of hormone and wounding treatments on the vegetative propagation of K. anthoteca seedlings and the susceptibility of these cuttings to AMF soil inoculums infection compared to some other bait species such as Sorghum bicolor and Puereria javanica. The results indicated that, K. anthoteca can successfully be propagated through stem cutting with only wounding and without hormone (auxin) applications. Analysis of variance tested at 5% significance level revealed no differences between the treatment means of hormone and wounding on the number of roots. Again, the lengths of the longest roots were not significantly different over the control treatment. In the trapping experiment, there were no significant differences in terms of root segment colonization between K. anthoteca cuttings and the other trapping species. This observation was however, frequent in the young and meristematic segments of the roots for K. anthoteca. An average root colonization of 32% was observed for K. anthoteca and the highest recorded by S. bicolor of 43%. Thus, about a third of root segments of K. anthoteca were colonized by AMF. There was also a significant positive correlation between percentage root segment colonization and the number of counted spores. The study concludes that wounding of K. anthoteca six-month old seedlings prior to vegetative propagation by cutting play vital role with respect to the rooting ability of the propagules compared to non-wounded propagules and also not significantly different from that of synthetic hormone application. Again, K. anthoteca is susceptible to AMF just like most tropical plant species in Indonesia. Finally, AMF soil inoculums can also be a good source of inoculants for establishing K. anthoteca in areas of degraded lands for revegetation purposes.

“…Leafless hardwood cuttings of Ulmus villosa Brandis ex Gamble, for instance, showed better rooting results when collected in the winter, period that precedes its vegetative growth (BHARDWAJ; MISHRA, 2005), just the opposite to what happened to B. x blakeana cuttings. In fact, those authors found higher carbohydrate levels in the winter cuttings than in the summer ones.…”

“…However, there are some intrinsic and extrinsic factors that may influence cutting survival, such as mother plant age, cutting collecting time, cutting extraction areas from the mother plant, use of growth regulators (BHARDWAJ; MISHRA, 2005) and substrate types. Furthermore, the specific genetic configuration seems to be determinant for the rooting process of some species and even clones, as some of them can hardly be induced to root production (NEVES et al, 2006;NOUAIM et al, 2002).…”

Vegetative propagation of bauhinia x blakeana, an ornamental sterile tree

et al. 2013

View full text Add to dashboard Cite

-Bauhinia x blakeana (B. purpurea x B. variegata) is a natural hybrid that has been cultivated in gardens, streets and parks. Due to its sterility, it must be vegetatively propagated. The objective of this work was to evaluate the viability of cuttings and grafting on its propagation. Semi-woody cuttings were collected during four seasons and treated with 0; 1,000; 2,000; and 3,000 mg L -1 of IBA. The experimental design was entirely randomized and the treatments were arranged in a 4x4 factorial scheme (four collecting times x four IBA concentrations) and five replications with 10 cuttings each, per collecting time and per IBA concentration. Characteristics of roots and shoots were evaluated after 90 days. The data means were compared by the Tukey test and submitted to the polynomial regression analysis. For the grafting experiment, B. variegata and B. variegata var. candida plants of six and 12 months were used as rootstocks and the splice graft and T-budding methods were tested. The experimental design was entirely randomized and the treatments were arranged in a 2x2x2 factorial scheme (two rootstock species x two grafting methods x two rootstock ages) and four replications with five plants each, per rootstock species, per grafting method and per rootstock age. Characteristics of shoots were evaluated after 90 days and the data means were compared by the Tukey test. B. x blakeana can be propagated by semi-woody cuttings collected in spring, without IBA application, or in summer, with the application of 3,000 mg L -1 of IBA. The tested grafting methods were not effective. de AIB. O delineamento foi inteiramente casualizado, e os tratamentos foram arranjados em esquema fatorial duplo (quatro estações do ano x quatro concentrações de AIB) e cinco repetições com 10 estacas cada, por concentração de AIB e por estação do ano. Características vegetais e radiculares das estacas foram avaliadas após 90 dias. As médias dos dados foram comparadas pelo teste de Tukey e submetidas à análise de regressão polinomial. Para a enxertia, mudas de seis e 12 meses de B. variegata e B. variegata var. candida foram usadas como porta-enxerto, e os métodos de garfagem inglês simples e borbulhia "T" invertido foram testados. O delineamento foi inteiramente casualizado, e os tratamentos foram arranjados em esquema fatorial triplo (duas espécies de porta-enxerto x dois tipos de enxertia x duas idades do porta-enxerto) e quatro repetições
