Abstract Blueberry cuttings are difficult to root, so alternatives that maximize their rhizogenic potential are essential for the expansion of the crop. The objective of this work was to evaluate the effect of the basal lesion and different methods of indolebutyric acid (IBA) on the rooting of ‘Woodard’ herbaceous cuttings, collected in two seasons. The experimental design used was completely randomized in a 3x2x2 factorial arrangement, totaling 12 treatments and five replications. The factors consisted of different ways of IBA application (talc and alcohol in the concentration of 1,000 mg L-1, and without IBA), season of collection (autumn and summer), and two types of cuttings (with and without lesion in the basal portion). Two hundred days after the beginning of the experiment, there was no significant effect of the basal lesion on the rooting of the cuttings. However, it was found that rooting is influenced by the season of collection, with greater leaf retention, dry weight, number of roots per cutting, length of roots and length of the largest root collected in summer. The application of IBA talc provided a higher percentage of rooted cuttings (61.0%) in relation to alcohol (31.0%) and control (41.0%) when collected in the autumn. There was no difference between seasons when IBA was applied with talc, however, the application with alcohol solution and the control resulted in higher percentages of rooted cuttings in the summer (70.0% and 67.0%, respectively). Summer was considered the best season to collect ‘Woodard’ blueberry cuttings, although the IBA applied with talc has increased the percentage of rooted cuttings in the autumn. The basal lesion did not promote an increase in rooting.

O presente trabalho teve como objetivo avaliar o desempenho propagativo de estacas semilenhosas de variedades de figueira, com o uso de ácido indolbutírico. As variedades avaliadas foram Roxo de Valinhos, White Genova, PI – 189 e Troiano e a dosagem empregada do ácido indolbutírico foi 2000 mg L-1. O delineamento experimental utilizado foi o inteiramente ao acaso, em esquema fatorial 4 x 2 (variedades x com e sem aplicação do regulador vegetal), com cinco repetições e dez estacas por parcela experimental. Foram avaliadas a porcentagem de estacas vivas, de estacas enraizadas e de estacas brotadas, número de brotos, comprimento da maior raiz (cm), número de folhas, volume da raiz (cm3), peso seco da raiz (mg) e peso seco das folhas (mg). As estacas que não receberam a aplicação do regulador vegetal tiveram maior porcentagem de estacas vivas, enraizadas e brotadas, com exceção das variedades Roxo de Valinhos e Troiano, que não apresentaram diferença na aplicação. Mediante esses resultados, foi possível concluir que não é recomendado o uso do ácido indolbutírico para essas variedades, na época de coleta das estacas correspondente ao mês de agosto.PALAVRAS-CHAVE: Ficus carica L., propagação, regulador de crescimento FIG TREE VARIETIES CUTTINGS ROOTING USING INDOLEBUTYRIC ACID ABSTRACT: The present study aimed to evaluate the propagative performance of fig trees cuttings with application of indolebutyric acid (IBA). The evaluated varieties were “Roxo of Valinhos, White Genova, PI -189 and Troiano and the dosage of indolebutyric acid used was 2000 mg L-1. The experimental design used was entirely random, in factorial scheme 4 x 2 (varieties x with or without application of plant regulator), with five replications and ten cuttings per plot. It was evaluated the percentage of live cuttings, rooted cuttings and sprouted cuttings, number of shoots, length of the largest root (cm), number of leaves, root volume (cm3), root dry weight (mg) and leaves dry weight (mg). The cuttings that did not receive treatment with indolebutyric acid had  higher percentage of live, rooted and sprouted cuttings, except for  Roxo of Valinhos” and Troiano varieties, which showed no difference among treatments . Based on the results, it is possible to conclude that the use of indolebutyric acid for such varieties is not recommended in August, month of  cuttings harvest in this study.

Abstract The objective of this work was to evaluate the rooting of herbaceous cuttings of CAMB-06 and APU-04 acerola cherry selections associated with the use of indolebutyric acid (IBA) and a concentration of aqueous extract of coco-grass. Cuttings were treated by immersion with different concentrations of IBA (0; 1,000; 2,000; 3,000; 4,000 mg L-1) and one application of aqueous extract of coco-grass in proportion 100% and placed to root in plastic boxes containing vermiculite. The experimental design was a completely randomized in a 2×6 factorial arrangement (two acerola cherry selections and six solutions for rooting) with four replicates of ten cuttings. After 90 days of cutting, the following variables were evaluated: cutting survival (%); leaf retention (%); rooted cuttings (%); sprouting (%); number of roots per cutting (%); length of roots (cm) and dry mass of roots per cutting (g). It was concluded that the application of IBA at 4,000 mg L-1 presented a better root development, resulting in a higher percentage of rooted cuttings and higher number and dry mass of roots in relation to IBA at 0 mg L-1 for CAMB-06 selection, while the APU-04 selection can be efficiently multiplied by herbaceous cuttings without the use of IBA. Under the conditions that the trials was conducted, the application of 100% aqueous extract of coco-grass was not effective in promoting the rooting of cuttings of CAMB-06 and APU-04 acerola cherry selections.

1. The effect in the rat of salbutamol infusion (1 μg min−1 kg−1) on acid-induced lung injury has been determined. Severity of lung injury was assessed by two techniques: the pulmonary clearance of 99mTc-diethylenetriaminepenta-acetate (99mTc-DTPA) and the lung wet/dry weight ratio, giving indices of alveolar epithelial permeability and transendothelial water filtration respectively. 2. Mean half-time of clearance of 99mTc-DTPA was increased significantly in rats who had intratracheal acid-induced injury and control (saline) intravenous infusion (19.4 ± 2.6 min) compared with non-acid-treated rats (98.1 ± 7.2) (P < 0.0001). However, those animals who had intratracheal acid injury and subsequent salbutamol intravenous infusion had significantly faster clearance (11.5 ± 1.9) than the acid and control infusion group (P < 0.05). 3. Gravimetric lung water in the acid-only rats (expressed as wet/dry weight ratio) was increased significantly (6.4 ± 0.3) compared with the non-acid-treated controls (5.4 ± 0.2) (P < 0.01). Acid-treated rats who had salbutamol infused had dramatically increased lung water (10.0 ± 0.6) (P < 0.001 vs acid and control infusion). 4. Intravenous salbutamol infusion itself produced no significant difference in the results for both techniques, compared with the non-acid-treated time-course controls. 5. Infused salbutamol accentuates acid-induced lung injury in the rat. Possible factors responsible for these findings include β2-adrenergic agonist mediated inhibition of hypoxic pulmonary vasoconstriction (HPV) and a predominant β1-adrenergic agonist inotropic effect of salbutamol with resultant rise in pulmonary artery pressure.

Drymis brasiliensis Miers is a specie of the Winteraceae family, commonly known as cataia or pepper bark. This research was carried out with the aim to study the rooting of semihardwood cuttings, subjected to different concentrations of indolebutyric acid (IBA), collected in four seasons of the year (autumn, winter, spring and summer). Cuttings were prepared with 10-12cm length, keeping two halved leaves. Bases of cuttings were treated as follows: control (100% water), 0; 500; 1500; 3000; 4500 and 6000mg L-1 IBA.One hundred and twenty after the planting the following variables were assessed: rooting percentage, number of roots per cutting, length of roots per cutting, cutting callus percentage, cuttings with new shoots and number of cuttings that maintained the initial leaves. The indolebutyric acid is not recommended for rooting of Drimys brasiliensis cuttings. The cuttings collected in winter were the ones that showed greatest rooting percentage (46.96%) for the production of nursery plant of Drimys brasiliensis.

ABSTRACT Propagation by cuttings is an alternative for obtaining citrus rootstocks. The exogenous application of indolebutyric acid (IBA), cutting collection season and genotypes used may affect the rooting and vegetative growth of citrus rootstocks cuttings. Two experiments were conducted to study the influence of these factors. In the first one, semi-hardwood cuttings from the 'Sunki' mandarin hybrids H49 and H77 were collected in the fall and late spring of 2013 and treated with IBA (0 mg L-1, 1,500 mg L-1 and 3,000 mg L-1). For each collection season, a 2 x 3 (two genotypes x three IBA concentrations) factorial scheme was adopted, in a randomized blocks design. In the second experiment, the development of cuttings that rooted in the late spring was evaluated until grafting. In this case, a completely randomized experimental design was adopted, with the hybrids H49 and H77. The IBA treatments positively influenced rooting and number of roots only in the fall collection, peaking at 23.3 % of rooted cuttings. In the late spring collection, rooting was close to 100 %, with the IBA treatment being unnecessary. Around 50 % of cuttings from the 'Sunki' mandarin hybrids were ready for grafting at 14 months after cutting.

Rooted cuttings of Taxus times media var. densiformis Rehd. were inoculated with the arbuscular mycorrhizal fungi Gigaspora gigantea (Nicol. & Gerd.) Gerd. & Trappe or Glomus intraradices Schenck and Smith and grown for 9-15 months in a greenhouse. At the completion of the experiments, leaves of inoculated plants contained significantly more chlorophyll (1.3-4.1 times as much) than did noninoculated plants. In addition, mycorrhizal plants had root systems that were significantly larger (1.3-1.4 times) and longer (1.7-2.1 times) than nonmycorrhizal plants, and they possessed significantly more branch roots (1.3-2.9 times). No differences in stem diameter and height or shoot dry weight were evident at the end of the experiments, although the number of buds was significantly greater in the cuttings inoculated with G. intraradices after 15 months.

Mindi besar (Melia dubia Cavanilles) is one of fast growing tree species from family Meliaceae which growing in tropical evergreen forests. The aim of this study was to determine the best combination of medium and growth regulator for vegetative propagation of mindi besar trees. The completely randomized factorial design was used two factors; medium (M) there were two types of media; zeolite (M1) and soil + rice husk (2:1 v/v) medium (M2), the growth regulator (H) had three levels; control (H0), pure coconut water (H1), and Auksin sintetis (H3). The study was conducted at two locations, first at green house with rooting room KOFFCO System and second at seedbed with rooting room containment model (MS). The research at greenhouse using rooting room KOFFCO System showed that interaction of media with growth regulator had a very significant effect on the percentage of fresh cuttings and rooted cuttings and had a significant effect on the number of primary roots. The averages of percentage of fresh cuttings and rooting were 83.3% and 66.7% for M1H2 and 76% and 60% for M2H0. The M2H1 reached 2.9 number of primary roots. At the MS model, the medium factor had significantly different only the number of secondary roots (18.11). The growth regulator factors had significantly different on the percentage of rooted cutting (3.33%), root lenght (10.5 cm) and root dry weight (0.18 g).Key words: containment model, KOFFCO system, Rootone-F, zeolite.

Abstract This study was conducted to determine whether treating seeds of ‘Sensation Mixed’ cosmos (Cosmos bipinnatus Cav.) and ‘Bonanza Gold’ marigold (Tagetes patula L.) with paclobutrazol (PB) could suppress seedling growth. Seeds were soaked in solutions of 0, 500 or 1000 mg PB/liter (ppm PB) for 16 hours at 25C (77F) or they were primed [−0.5 MPa (−5 bars) for 7 days at 20C (68F)] in Grade 5 exfoliated vermiculite moistened with 0, 500 or 1000 ppm PB solltuions. Soaked and primed seeds were dried for 1 day at 19C (65F) and 25% relative humidity. These seeds and control (non-treated) seeds were sown into plug cells containing peat-lite. Increasing PB concentration decreased cosmos shoot height at 32 days after planting (DAP), but decreased emergence percentage, responses that were more pronounced with priming than with soaking. A 1 ppm PB growth medium drench [30 ml/cell(0.2 mg PB/cell)] and, to a greater extent a 10 mg PB/liter (ppm PB) shoot spray [2 ml/shoot (0.02 mg PB/shoot)], both applied at 10 DAP, resulted in greater cosmos shoot height suppression at 32 DAP than treatment of seeds with 1000 ppm PB. Soaking marigold seeds in 1000 ppm PB failed to decrease shoot height below those of plants from non-treated seeds at 32 DAP. However, exposure to 1000 ppm PB during priming of marigold seeds resulted in a similar shoot height suppression (13%) as the growth medium drench, and similar shoot dry weight reduction (21%) as the shoot spray. Suppression of shoot growth by this seed treatment was short-term since by five weeks after transplanting into 15 cm (6 in) pots, only marigold plants that had received the growth medium drench or shoot spray were smaller than those of control plants. Treating marigold seeds with 1000 mg ppm PB used about one-fifth the PB used to drench the growth medium.
