ABSTRACT: The objective of this study was to evaluate the effect of different types of cuttings and indolebutyric acid (IBA) concentration on the vegetative propagation of Lippia insignis , L. lasiocalycina , and L. thymoides . The experiment was conducted in a 2×5 factorial table, by using 2 types of cuttings (apical and medial) and 5 IBA concentrations (0, 250, 500, 750, and 1000mg·L-1) in a Completely Randomized Design (CRD), with 4 replications and 10 cuttings per plot. For the propagation of L. insignis , apical cuttings are the most suitable, whereas for L. thymoides and L. lasiocalycina species, both apical and medial cuttings may be used. The application of IBA is not necessary for propagation by cutting of the three species of Lippia.

Propagation Methods

The use of rootstocks originated from sexual propagation results in serious problems for peach culture, being vegetative propagation an important alternative to minimize these problems partially. Among vegetative propagation methods, the use of mini-cuttings constitutes an innovation against the conventional mini-cutting method, which, in some species, have promoted an increase in productivity, uniformity and rooting percentage. Thus, the objective of the present work was to evaluate the viability of Japanese apricot propagation through herbaceous mini-cuttings, by testing different concentrations of IBA (0, 1.000, 2.000 e 3.000 mg.L-1) and types of mini-cuttings (apical, median and basal), in a completely randomized design with four replications. Prepared with two buds and a leaf cut in half, with two lesions on the basis, they were immersed in IBA solution, for 10 seconds, and placed in transparent, articulated plastic packages with vermiculite growing medium. Next, they were placed in a greenhouse under controlled temperature. Sixty days after installation, the percentage of rooted mini-cuttings, number and length of the three largest roots were evaluated. During rooting, the apical, median and basal mini-cuttings showed higher percentage using 1.000 mg.L-1 of IBA.

Cestrum corymbosum é um arbusto ornamental nativo do Brasil. A pesquisa visou estudar sua propagação sexuada e vegetativa, avaliando a germinação e o crescimento e testando o efeito do tamanho das estacas e do ácido indolbutírico (AIB) no seu enraizamento e desenvolvimento. Para avaliar a germinação, foram utilizadas seis repetições de 100 sementes. Em seguida, 200 plântulas foram transferidas para embalagens individuais mantidas em canteiro. O experimento de propagação vegetativa, com delineamento inteiramente casualizado em arranjo fatorial 3 x 2, constituiu-se na combinação de três concentrações de AIB (0, 1000 e 2000 mg.L-1) e dois tamanhos de estacas (8 e 15 cm). As estacas foram plantadas em substrato comercial Plantmax HA®. No experimento de propagação sexuada, verificou-se elevada germinação (92%), assim como alta taxa de sobrevivência após repicagem para recipientes individuais (99,5%). Para o experimento de propagação vegetativa, foi detectada influência significativa do tamanho das estacas em relação à sobrevivência, enraizamento (P < 0,01) e número de folhas (P < 0,05). Estacas de 8 cm apresentaram melhor sobrevivência (93,3%) e enraizamento (91,3%). A aplicação de concentrações de AIB não resultou em diferenças significativas (P < 0,01), demonstrando não ser necessária para o enraizamento dessa espécie.Palavras-chave: Germinação; enraizamento; ácido indolbutírico; espécie nativa; Solanaceae.AbstractPropagation of Cestrum corymbosum by seeds and cuttings. Cestrum corymbosum is an ornamental bush native from Brazil. This research aimed to study the sexual and vegetative propagation of this species, evaluating germination and growth of the seedlings, and testing the influence of indolebutyric acid (IBA) and cuttings size on its rooting and development. In order to evaluate germination, six repetitions of 100 seeds were considered. After that, 200 seedlings have been transplanted to individual packages kept in a bed. The vegetative propagation experiment has been arranged in a 3 x 2 factorial completely randomized design that comprised the combination of three IBA concentrations (0, 1000 and 2000 mg.L-1) for two cuttings sizes (8 and 15 cm). The cuttings were planted in commercial substrate Plantmax HA®. A high germination (92%) has been verified. The survival after transplantation was very high (99.5%). It was detected statistically significant influence of the cuttings size on plants survival, rooting (P<0.01) and leaves number (P<0.05). The cuttings of 8 cm  presented better survival (93.3%) and rooting (91.3%) rates.

Reproductive traits determine the selection method in plant breeding. The benggala grass of the Hamil cultivar was thought to be apomictic; thus, a study was conducted to determine its reproduction. The research began by studying the morphological characters, continued with observing the generative phase and seed production of the cultivar planted from seeds (generative) and from pols (vegetative). The experiment was conducted in the greenhouse of the Research Institute of Animal Production. The experimental design was a completely randomized design with ten replications, and the treatments were different types of plant materials: seeds and pols. The Hamil cultivar taken from RIAP Collection was planted in pots with a diameter of 40 cm and a height of 30 cm. The results showed that most of the morphological characters of the Hamil cultivar planted from seeds and from pols were not different (P >0.05), so it was presumed that they were apomictic. The difference in morphology was only in the length and width of the flag leaves and the length of the internodes, where the cultivars planted using seeds were higher. The production of seeds, pithy seed weight, and seed germination of cultivars planted using seeds were higher (P <0.05). Further research is needed to determine the apomixis properties based on cytologically Hamil cultivars.   Keywords: apomixis, benggala grass, morphology, plnting material; seed

In the search for more efficient techniques for the propagation of peach cuttings, this study aimed to evaluate the rooting of hardwood cuttings of peach rootstock genotypes under different indolebutyric acid (IBA) concentrations. In the winter of 2016, the basal end of cuttings of genotypes 1701-1, 1701-2, 102-1, 102-2, 202-1 and 'Okinawa' were dipped into solutions with five concentrations of IBA (0, 1000, 2000, 3000 and 4000 mg mg L-1) for 5 seconds. The cuttings were then placed in sand in plastic trays and kept in a mist chamber. The experiment was arranged in a 6x5 factorial, completely randomized design, with 5 replications, and each plot consisted of eight cuttings. After 59 days, the variables related to rooting and root quality were evaluated. Genotypes 102-1 and 202-1 showed high adventitious rooting potential in hardwood cuttings, with 76.8 and 66.5% of rooting, respectively. The concentration of 2000 mg.L-1 of IBA acid can be recommended for the treatment of hardwood cuttings of the tested rootstocks for propagation in the winter.

ABSTRACT The objective of this work was to evaluate the effect of six indole-3-acetic acid (IAA) concentrations and three immersion times in IAA solutions on the vegetative propagation of Spondias dulcis and Spondias tuberosa by stem cuttings. The experiment was conducted in a greenhouse, using a completely randomized design, with a 6×3 factorial arrangement consisting of six indole-3-acetic acid concentrations (0, 2, 4, 6, 8, and 10 g L-1) and three immersion times (8, 16, and 24 seconds), with ten cuttings of S. dulcis and S. tuberosa per plot, and three replications. Percentage of surviving cuttings, and percentage of rooted cuttings, number of leaf buds, number of roots per cutting, root length, and total fresh weight were evaluated at 180 days after planting. Data were subjected to analysis of variance by the F test and to regression analysis. Vegetative propagation from woody cuttings of S. dulcis is not viable to produce seedlings, thus, new studies on this technique for this species are needed. Vegetative propagation from woody cuttings of S. tuberosa is satisfactory, but with low efficiency for improvement and emergence of new shoots and roots; it is more effective when using a concentration of 10 g L-1 of indole-3-acetic acid and immersion time in the solution of 16 seconds.

Corn (Zea mays) is one of the most cultivated poaceae in the world with high agricultural potential. It is propagated through seeds, which sometimes remain stored until the sowing period. Among the various forms of storage, some aspects related to the environment and the type of material that constitutes the packaging may compromise the viability and vigor of these seeds. Therefore, the objective of this study was to evaluate the physiological quality of corn seeds stored in different types of packaging and subjected to conditions of high temperature and relative humidity throughout storage. For this purpose, water content, germination and vigor were evaluated through the cold test. A completely randomized design in a 4 x 4 factorial scheme (packaging x evaluation times) with four replications was used. Data were subjected to analysis of variance and regression, and the means were compared by Tukey test at 5% probability, using the Sisvar 5.3 statistical software. It was concluded that, in 45 days of storage, the water content in corn seeds reached values of up to 13.62%, which resulted in a reduction in the vigor due to high respiration caused by the storage temperature.
