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).

Pyrostegia Venusta

The flame vine (Pyrostegia venusta (Ker-Gawl.) Miers) is a semihardwood vine, vigorous, native, native, occurring in all Brazilian biomes and ornamental potential. Technical information about the propagation of this species will contribute to the production of seedlings and with that, their greatest use in landscaping. This study aimed to evaluate the influence of the number of leaves and nodes in rooting intermediate flame vine. The experiment was conducted under conditions of intermittent mist. The experimental design was a randomized block in factorial 2 x 3, being respectively cuttings with one or two nodes, and zero, one or two leaflets. We used four replicates with plots consisting of 12 cuttings placed in substrate of rice hulls in polystyrene trays with 72 cells. We evaluated at 84 days the porcentage of rooted cuttings, length of shoots, dry weight of shoots and, per cutting, average: number of roots - first order; maximum length of each root of the first order, volume and dry weight of roots. It was observed that cuttings with two leaflets enabled 66% of rooting, greater length and dry mass of shoots. The higher quality of the root system occurs with stakes with two leaflets and two nodes. The spread of flame vine is efficient with semi-hardwood cuttings with two nodes and two leaflets, kept in a greenhouse under intermittent mist.

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.

In the commercial production of guava seedlings (Psidium guajava L.) the quality of the cuttings, homogeneity, high percentage of rooting are the factors important to be analyzed. Therefore, as the Século XXI cultivar is recent, it is necessary to do more studies regarding the behavior of this guava to the factors that aid in the rhizogenic process. The objective of this work was to verify the concentrations of indolebutyric acid (IBA) that provide the best rooting of cuttings herbaceous and semihardwood, as well as to verify the best kind of cuttings used for vegetative propagation the guava cuttings cultivar ‘Século XXI’. The experimental design was completely randomized in a 5 x 2 + 1 factorial design, beginning with five concentrations of IBA (0, 1000, 1500, 2000 and 2500 mg L-1), two kinds of cuttings (herbaceous and semihardwood) and one control treatment (immersed in distilled water for 12 hours), with four replications and 10 cuttings per plot. In relation of the variables: the percentage of cuttings live without roots, callus, number of roots and dry weight of shoots did not present significant interaction among treatments, not adjusting to any regression model. Therefore, concluding that the herbaceous cutting is the most indicated for the propagation of guava seedlings of ‘Século XXI’; The concentration of 2500 mg L-1 of IBA promotes a higher percentage of rooted semihardwood cuttings without leaf; The hormone solution diluted with alcohol 50% (v/v) resulted in toxicity for herbaceous and semihardwood cuttings cv. Século XXI.

Our objective was to investigate the influence of alternative substrates based on stem decomposed by babassu and humic substances in the production of sunflower seedlings. The experimental design was randomized blocks, in a 3 x 4 factorial scheme (substrate x humic substances). Twelve treatments were studied, T1 (100% babassu stem decomposed (BDS) + 0 ml L-1 HS), T2 (100% BDS + 12.5 ml L-1 HS), T3 (100% BDS + 25 ml L-1 HS), T4 (100% DBS + 50 ml L-1 HS), T5 (50% DBS + 50% LAd + 0 ml L-1 HS), T6 (50% DBS + 50% LAd + 12, 5 ml L-1 HS), T7 (50% DBS + 50% LAd + 25 ml L-1 HS), T8 (50% DBS + 50% LAd + 50 ml L-1 HS), T9 (100% LAd + 0 ml L-1 HS), T10 (100% LAd + 12.5 ml L-1 HS), T11 (100% LAd + 25 ml L-1 HS) and T12 (100% LAd + 50 ml L-1 HS). Each treatment was performed in four replications with one seedling per plot, totaling 48 plots. The DBSxHS interaction provided increases in root length, root volume, basal diameter, number of leaves, plant height and parameters related to inflorescence. The substrate with 100% decomposed babassu stem, together with the dose of 12.5% humic substance, is the best option for producing 'IAC Uruguay' sunflower seedlings. Further research on the use of DBS and HS is needed to address the use and purpose in producing new crops.

Abstract Fig tree (Ficus carica L.) stands out due to its range of cultivation and easy adaptation to diverse edaphoclimatic conditions. In addition to its adaptability, fruits have nutraceutical characteristics and are used in industry and for fresh consumption, widely appreciated by the world cuisine. Due to lack of manpower and phytosanitary problems, the area planted in Brazil has decreased recently. To overcome these obstacles, the production of quality seedlings is the first step to obtaining productive and healthy orchards. Therefore, the aim of the present literature review was to gather data referring to advances in research related to the fig tree propagation. Currently, the methods found for fig tree propagation consist of seedling production, where entomophilic or vegetative pollination occurs. Commercially, the propagation method by cutting is still the most used for this crop; however, other methods can also be used, such as the use of burrs or plunging and grafting techniques and tissue culture. Although there is a diversity of propagation methods and new technologies being developed, cuttings remain the most feasible method. In addition, obtaining healthy and quality seedlings is one of the main problems currently found in ficiculture, since, in addition to the scarcity of studies related to propagation, the use of resistant cultivars and pathogen-free substrates should be prioritized due to susceptibility of fig trees to nematodes. Thus, further studies should be carried out in order to seek new information on the cultivars most adapted to each locality, as well as improvements in propagation and cultivation techniques.

Reproduction Method

Arachis pintoy can be reproduced in generative but also vegetative way, for example through cuttage. Problems arising from this reproduction method is the difficulty to form roots. The success rate of this method depends significantly on the size of the formed callus. To analyze the content of nutrients contained in the cuttage stem, we have to cut off the stem. And then it’s necessary to find out additional factors that can influence the forming of the callus with a large percentage of rooting. One alternative solution is the provision of coconut water which believed to contain a variety of nutrients and growth substances. Therefore, we conducted a study to find out the interaction of these two factors on the growth of Arachis pintoy The purpose and goal of this research is to study and identify the growth Arachis pintoy which treated with coconut water its influences on the stem length. This research has been performed in Agrostology Lab of Animal Husbandrys Faculty of Sam Ratulangi University, during a period of 60 days. The research materials consists of Arachis pintoy, Coconut Water and soil. While the research method use 2 experimental factors: Factor A is the Coconut water, Factor B is the after-cuttage-stem length of Arachis pintoy, which arranged through completely randomized design (CRD). Each factor consists of 3 treatments, which repeated 3 times. These factors are as follows: A = volume of Coconut water, A1 = 100 ml of coconut water, A2 = 200 ml of coconut water, and A3 = 300 ml of coconut water. Factor B = stem length of Arachis pintoy, B1 = 10 cm, B2 = 15 cm, and B3 = 20 cm. And the variables which measured in this study were plant height, dry weight of roots and the roots volume. The results showed that administration of coconut water and the length of the cuttings as well as the interaction of two factors give significant effect (P < 0.05) to the growth of the number of leaves and root dry weight of the Arachis pintoy . Furthermore, coconut water does not give effect to the root volume and a combination of two factors do not impact on the growth of plant height. From the data analysis and discussion for all variables in this study , we can conclude that the best combination of growth in the number of leaves , dry weight of roots and root volume is the provision of 300 ml of coconut water and 10 cm stem length. Keywords: Arachis pintoy, coconut water and stem length

Furanocoumarins are the major phytoalexins of Ficus carica and are effective natural drug candidates for treatment of several types of cancer and skin disease. The objectives of this study were to analyze and quantify linear furanocoumarins, mainly psoralen and bergapten, in wood and bark of stems from eight Algerian varieties of fig and to establish the differences in the content of these metabolites in the eight local samples. Psoralen and bergapten contents in the stem bark and wood (in μg/g DW) varied respectively from 146.6 to 1110.3 and from 395.7 to 1671.8 for psoralen, and from 114.3 to 524.0 and from 144.2 to 718.6 for bergapten. This study fills a gap in our knowledge of furanocoumarin distribution in different parts of the fig tree. Psoralen and bergapten concentrations were higher in the wood than in the stem bark. Most of the dark fruited fig trees produce these two coumarins more than the green ones.
