O experimento foi conduzido em delineamento experimental inteiramente casualizado em esquema fatorial 5x4 com 4 repetições, em casa de vegetação no Núcleo de Engenharia de Água e Solo (NEAS), pertencente à Universidade Federal do Recôncavo da Bahia, localizada no município de Cruz das Almas - BA. A cultivar utilizada foi a Anão de Jardim e os tratamentos foram constituídos por cinco concentrações de água residuária diluídas em água de abastecimento (0, 25, 50, 75 e 100%) e quatro lâminas de irrigação obtidas a partir das percentagens de evaporação do tanque classe A (70, 90, 110 e 130%). As variáveis analisadas foram: altura da planta (AP), diâmetro do caule (DC), número de folhas (NF), massa fresca e seca da parte aérea (MFPA e MSPA), dias para o aparecimento de botões florais (DABF), dias para o período de floração (DPF), dias para abertura total dos capítulos (DATC), diâmetros internos e externos dos capítulos (DI e DE), massa fresca e seca dos capítulos (MFC e MSC), além da estimativa do consumo hídrico da planta (CH). Os resultados obtidos mostraram que, com exceção da AP, todas as variáveis foram influenciadas pelas lâminas de irrigação ou pelas diluições de água residuária, não havendo influência significativa da interação entre os fatores para nenhuma das variáreis avaliadas. O uso de água residuária e a lâmina de 110% da evaporação do tanque classe A favoreceram o desenvolvimento do girassol. O menor e maior consumo hídrico da cultura foi observado nas lâminas de 70 e 130%, respectivamente. Palavras-chave: Reuso, cv. Anão de jardim, tanque Classe A.  OLIVEIRA, M. L. A.; PAZ, V.

The production of the turnip (Brassica napus L.) in Ecuador, depends largely on the use of agrochemicals, whose indiscriminate use causes negative effects on the environment. Agricultural homeopathy has emerged as an ecological alternative to improve the health status of plants. In order to help improve the sustainable production of vegetables, the effect of two centesimal dynamics (7CH and 31CH) of three homeopathic medicines for human use was evaluated: Silicea terra (SiT), Natrum muriaticum (NaM) and Phosphoricum acidum (PhA ), on the germination, emergence and vegetative development of B. napus plants, applying a completely randomized 2×3+1 block design with three repetitions for the three stages of the crop. The variables evaluated during germination and emergence were: percentage of germination and emergence, length of stem and radicle, fresh weight of the aerial part and radicle, dry weight of the aerial part and radicle. The variables evaluated during vegetative development were: plant height, stem diameter, number of leaves, weight, leaf area and productive yield. Signif icant differences were recorded in all the variables and stages of development studied. The highest germination values corresponded to SiT-7CH and PhA-7CH (100%), surpassing the control group (83.5%). The PhA-7CH and NaM-31CH treatments stimulated stem growth in the germination stage (3.40 cm) and NaM-7CH root growth (4.07 cm) in the emergence stage. During the vegetative development, the plants with the highest production were those treated with NaM-7CH. The highest prof itability of the crop (71.33%), with a benef it / cost ratio of 1.7% was obtained with SiT-7CH. The results obtained suggest that agricultural homeopathy has potential in horticulture, since all treatments favorably influenced the response variables during germination, emergence and vegetative development of (Brassica napus L.).

The propagation of the hibiscus is done preferably by cutting. However, the success of this technique depends on the internal and external conditions cuttings, that will influence directly into your rooting capacity. In this sense, the objective was to evaluate the effect of three types of cuttings (apical, middle and basal) and four concentrations of IBA (0, 1000, 3000 and 5000 mg L- 1) in the propagation through cuttings of Hibiscus rosa-sinensisL. cv. Snow Queen. The experiment was conducted in a greenhouse under intermittent mist at the Federal University of Piauí (UFPI), Campus Profa. CinobelinaElvas, Bom Jesus-PI for the period from May 23 to July 7, 2012. The experimental design was completely randomized in a factorial arrangement 3x4 (Type of cuttings x Concentration IBA) with four replications. At 45 days after implantation of the experiment were evaluated: percentage of rooting, survival rate, number of shoots, number of leaves, average root length, dry weight of shoot and root dry weight. There was no significant interaction between the factors studied. There is effective for cutting type. The technique of propagation by cuttings of Hibiscus rosa-sinensis L. cv. Snow Queen is efficient through the use of basal cuttings.

Propagation Technique

Guabiju tree is usually propagated by seeds, although this method presents disadvantages, such as a long juvenile period and great genetic variability, resulting in uneven plants which makes management and the establishment of commercial orchards difficult, in addition to the delay in the production entry. The objective of this work was to test the propagation technique by mini-cutting in guabiju tree. The experimental design used was completely randomized, with a 2 x 2 x 3 factorial (ontogeny of the matrix plant x cut length x IBA concentration), with four replications and 20 mini-cuttings per experimental unit. A hundred and twenty days after the implantation of the experiment, the rooting percentage and callogenesis of the mini-cuttings, the secondary root total length, the aerial part and number of leaves were evaluated. The rooted mini-cuttings were transplanted into larger containers with substrate, and after 60 days of transplantation, their survival percentage was analyzed. The highest rooting percentage was obtained with 0 mg L-1 of IBA with an 57.69% average. Mini-cuttings had a high percentage of survival, with 87.5% being the lowest, presenting a satisfactory result. For the guabiju tree propagation by mini-cutting, it is recommended not to use IBA and adopt a length of four centimeters, using a juvenile matrix plant.

ABSTRACT: The persimmon tree is propagated by grafting and the rootstocks are produced from seeds. Grafting is done in July, which coincides with the time when the persimmon trees are pruned. But, at this time, many rootstocks are not yet eligible to receive the grafts. In this case budsticks/cleft storage is an option. Thus, this study aimed to verify the feasibility of cold storage of budsticks/cleft and verify the grafting method to promote better graft development. Rootstock was sown in August 2012 and the branches were collected in July 2013. Part of the branches was used for grafting (budding and cleft graft methods) in one-year old rootstocks and the other part was stored at low temperature (cuttings wrapped in moistened paper and then wrapped in polyethylene bags placed in cold storage at 4°C), during the months of August to December. Every 30 days, a number of branches was removed from the cold storage to perform grafting by budding and cleft and to quantify total sugars and starch in the budsticks/cleft stored. One hundred and twenty days after the grafting was performed, the length and diameter of the bud, number of leaves, sprouting percentage, dry weight of aerial part and root from the grafts were measured. It was concluded that there is no difference in the budding graft for different periods, but in seedlings grafted by the cleft grafting method there is greater growth when the clefts have been in cold storage for 60 to 120 days.
