Breadnut (Artocarpus camansi, Moraceae) is known throughout Amazonia, but its clonal form, breadfruit (A. altilis), is not, although it has much more commercial potential. To facilitate the promotion of breadfruit, a simple form of vegetative propagation was developed, and nursery plants were distributedto promote this species. Bottomless PET-bottles showed useful in creating the humid environment needed for the rooting of breadfruit cuttings. It is important to insist with farmers that breadfruit is different from breadnut and needs more care. The developed mini-greenhouse substitutes a misting installation, does not depend on electricity or running water and can be used for rooting of cuttings and grafting of small quantities of woody species. Apoam’s organic market in Manaus played an important role in the promotion of breadfruit’s cultivation and commercialization. A self-service lunchroom was useful in the promotion of this food unknown in Manaus.

Abstract Greenwood cuttings from greenhouse-produced tamarack seedlings and 3- to 10-year-old tamarack wildlings transplanted from natural stands in north-western Ontario were rooted under mist in peat-vermiculite. Eighty-five percent of cuttings from seedlings rooted; treatment with indolebutyric acid increased number of roots per cutting, but not rooting percent. At 6 weeks after planting, rooting of cuttings from wildlings averaged 66%, and at 12 weeks, 91%. Twelve-week rooting percent of cuttings from individual ortets ranged from 12 to 100, but cuttings from the majority of ortets exhibited 100% rooting. Nearly all rooted cuttings survived overwintering outdoors and initiated normal shoot growth after forcing in mid-winter. The described propagation system is recommended for production of container stock for tamarack plantations. North. J. Appl. For. 3:91-93, Sept. 1986.

Forest trees possess high genetic diversity and high heterozygosity which allow adaptation to changing environmental conditions. There is a tendency to propagate successful and unique genotypes, which are identified at their mature stage in the forests, for future improvement programs and conservation purposes. However, vegetative propagation of mature forest trees is still a challenge in many conifers. In this study, we focused on improving the rooting of cuttings of mature and old Pinus halepensis and its hybrids. We observed that storage of cuttings before rooting at 4°C for 4 weeks and prolong immersion of cuttings in a solution containing 400 mg/l of indole-3-butyric acid, 5 mg/l of the auxin conjugate 2-(2,4-dichlorophenoxy)propanoic acid-glycine methyl ester, and 0.01% of Amistar fungicide significantly improved rooting of mature cuttings. The active ingredient in Amistar is azoxystrobin, an uncoupler of respiration, which seems to directly promote rooting. Rooted cuttings of selected clones demonstrated unique and uniform growth performance, most likely delivering the intrinsic growth parameters of the mother trees. It was also observed that trees growing under drought stress possess improved rooting ability. By using rooted cuttings, it will be possible to study the relationship between growth rate and adaptation to semi-arid climate conditions. The ability to clonal propagate mature and old P. halepensis trees not only enables vegetative propagation of elite trees for improvement programs, but also provides an opportunity to preserve unique naturally occurring old P. halepensis genotypes.

Cuttings from the upper and lower regions of a Norway spruce tree were treated with talc only, and with talc containing 1000 p.p.m. indolylacetic acid. Ten weeks after being planted in sand, 43% of the upper and 75% of the lower cuttings were rooted. Hormone treatment increased the number of roots per rooted cutting but decreased the mean length of root. Lower cuttings produced twice the length of root of the upper cuttings, and the mean length of individual roots was also significantly greater. Nineteen weeks after being planted, the cuttings not rooted at 10 weeks were re-inspected, and gave final rooting values for the experiment of 48% for upper cuttings and 86% for lower. Physiological differences are consequently suggested in cuttings taken from the upper and lower regions.

Abstract The seeds of Plukenetia polyadenia have high levels of unsaturated fatty acids and are used as medicine and food for native people in the Peruvian and Brazilian Amazon. The objective of this study was to develop a method for vegetative propagation of Plukenetia polyadenia by rooting of cuttings. The experiment was laid out in a randomized complete block design with 12 treatments and 3 replications of 8 cuttings, in a 3 × 4 factorial arrangement. The factors were: 3 levels of leaf area (25, 50 and 75%) and 3 indole-3-butyric acid - IBA concentrations (9.84, 19.68 and 29.52mM) and a control without IBA. Data were submitted to analysis of variance and means were compared by Tukey test at 5% probability. Our results show that the use of cuttings with 50% of leaf area and treatment with 29.52mM of IBA induced high percentages of rooting (93%) and the best root formation. Vegetative propagation of Plukenetia polyadenia by cuttings will be used as a tool to conserve and propagate germplasm in breeding programs.

Sea buckthorn (Hippophae rhamnoides L.) is used in beverages, pharmaceuticals, cosmetic products, and animal feeds. Although sea buckthorn has been shown to be easy to propagate vegetatively, currently, there is little information on reliable techniques to vegetatively propagate the plant repetitively within a single year. To address this, three experiments were conducted to study whether season and chilling affected the successful rooting of cuttings. Four cultivars, ‘Chuskaya’, ‘Golden Rain’, ‘Lord’, and ‘Sunny’, were used in the season- and chilling-effect experiments. Hardwood and softwood cuttings from field-grown plants did not root from October to December. The percent of rooted cuttings in January was cultivar-dependent. The number and percent of rooted greenhouse-produced cuttings were significantly affected by length of chilling. Most cuttings were produced and the highest percent rooted when the plants chilled for at least 6 wk. ‘Lord’ had the most and ‘Golden Rain’ the least number of rooted cuttings. This study indicated that greenhouse-grown stock plants were a viable source of sea buckthorn cuttings for vegetative propagation. When combined with field-grown sources, it is possible to produce sea buckthorn planting material year-round.

Abstract Vegetation analysis in ten central Florida cypress (Taxodium distichum) swamps was undertaken to determine the response of woody species composition to clearcutting. Line transects through swamps that had been harvested by clear-cutting within the last 5 years demonstrated that all but one of these swamps are likely to recover their original species composition and a normal stem density. Cypress was the major tree species in all swamps examined except one that had been severely burned by a wildfire. Both natural seedlings and vegetative propagation are important avenues of cypress reproduction following clearcutting. South. J. Appl. For. 13(3):123-126.

The vegetative propagation by cuttings can be an advantageous alternative to the production of Himatanthus sucuuba seedlings because it allows the obtention of a large number of plants genetically identical to the matrix plant in a shorter time and space. However, such a technique is simultaneously influenced by different factors that can compromise its success. In this sense, the present study aimed to evaluate the effect of different types of cuttings and indole-3-butyric acid (IBA) concentration, on the survival and rooting of cuttings of H. sucuuba. The experimental design used was in randomized complete blocks, with a factorial arrangement: 2 types of cuttings (with and without leaves) and 3 concentrations of IBA (0, 1000 and 3000 mg L–1). After 100 days, were evaluated the following variables: survival (%), rooting (%), number of roots per cutting, length of the largest root (cm), number of leaves and dry biomass. The data were subjected to analysis of variance (ANOVA) and means compared by Tukey’s test at p < 0.05. The survival and rooting percentages were higher than 70% in all treatments. There was no significance for the interaction of the factors analyzed, neither for the effect of AIB, analyzed in isolation. The type of stake exerted the greatest influence, with emphasis on the cuttings with leaves, which stood out in most of the factors analyzed. The propagation of H. sucuuba to cuttings was considered viable, and the maintenance of the leaves, associated with juvenility of the propagules, was determining factors in the conditions in which this study was developed.

Wild populations of Spigelia marilandica, a clump-forming perennial, are being destroyed because of its recent popularity and the plant is now becoming rare in its native habitat. The effect of the stock plant environment on the rooting capability of Spigelia marilandica cuttings is the primary focus of this research. Cuttings were obtained from greenhouse (GH) grown plants on a monthly basis, and from plants maintained in outside field beds (FB), season permitting. Cuttings were dipped in Hormodin 1 (1000 IBA), placed in a perlite:peat mix, and put under mist for 8 weeks. During the experiment, 91% rooting of cuttings obtained from GH-grown plants and 35% rooting of cuttings obtained from FB-maintained plants was observed. Cuttings from GH-grown plants averaging 39 roots/cutting (average FW/cutting = 1.243 g, average DW/cutting = 0.1574 g) were compared to cuttings obtained from FB-maintained plants averaging 9 roots/cutting (average FW/cutting = 0.6041 g, average DW/cutting = 0.0663 g). A statistically significant difference was found between the two stock plant environments, with the cuttings from the GH-grown plants having an advantage over the cuttings obtained from the FB-maintained plants. A separate comparison was made of the cuttings obtained from the GH-grown plants over the 12 months of the experiment and the analysis showed no significant difference in the average FW/cutting, DW/cutting, and the number of roots/cutting.

ABSTRACT Commercial reforestation of Brazilian native species to produce hardwood for sawmills has been recently intensified in the country. Among the potential species planted by the logging industry is guanandi (Calophyllum brasiliense Cambess) because it is widely distributed in the country, highly adapted to different soil and climate conditions, good bole form and high quality timber. The development of genetic improvement programs should prioritize gains in productivity and yields in the medium and long term. For such programs to be successful, the study of vegetative propagation techniques to abbreviate steps in forest improvement and allow its mass production is fundamental. To assess the viability of vegetative propagation of the species, two successive experiments were carried out during two years testing the best type of cutting, hormone concentration and management. Different cuttings types submitted to increasing doses of indole-butyric acid (IBA) were tested to evaluate survival, sprouting, rooting and callus formation. Results indicate that the species is viable for vegetative propagation with 85 to 90% rooting of cuttings from seedlings in the IBA concentrations of 3000 to 7000 mg.L-1. For the cuttings, sprouting from the base of adult trees 3000 mg.L-1 was the best concentration of IBA.
