General Aspects

Potted plants have wide appeal among ornamental plants and one of the most produced for the market belong to the genus Kalanchoe. One aspect to be observed in potted plants is their durability post-production when maintained in indoors conditions as offices and homes. This study aimed to evaluate the durability of the pot post-production life of three species of Kalanchoe (K. marmorata, K. thyrsiflora and K. tubiflora) on different substrates. The experiment was arranged in a completely randomized design with 40 replicates per treatment in factorial 3 x 2 (three species of Kalanchoe x two substrates - washed sand and coconut fiber). After 30 days, it was evaluated the general aspects as changes in color, leaf abscission and shading of the stem apex. It was found significant differences between species and also between the substrates tested, but only in relation to the general aspects. The species Kalanchoe marmorata and K. tubiflora stood out by receiving top grades in most of the evaluated characteristics. The best substrate that provided plants the maintenance of the most of their ornamental characteristics over the 30 days was the coconut fiber.

Bromeliads have been gaining ground in the economic scenario due mainly to their use as ornamental plants. Bromeliads of the genus Dyckia exhibit different morphologies, and therefore, have relevance in this market. However, some species are threatened due to the extraction of plants from their natural environments. Many of these species are endemic and native to Brazil and there are few studies on their seed physiology; hence, expansion of research into this topic is essential. An alternative for the preservation of such plants is the production of seedlings using seeds. To this end, the objective of this work was to evaluate the physiological potential of seeds of Dyckia brevifolia, Dyckia beateae, and Dyckia excelsa at different temperatures, and determine the number of days to carry out the tests. A completely randomized design was adopted, with three species of Dyckia, analyzed separately, and four temperatures (20, 25, 30, and 35 °C). The following were evaluated: first germination count, germination, germination speed index, length of seedling, and seedling dry weight. The data were analyzed using the Sisvar software for normality and homogeneity, and when the assumptions were met, they were subjected to analysis of variance using the F test (p < 0.05) and the means were compared using the Tukey test at 5% probability. Seeds of D. excelsa emit the radicle more quickly at 20 and 35 °C; however, temperatures of 25 and 30 °C provide better conditions for seedling growth and development. The greatest vigor of D. brevifolia seeds is observed at temperatures of 30 and 35 °C. Seeds of D. beateae emit the radicle more quickly at 20 °C, and the largest seedlings are observed at 35 °C. The first germination count of D. brevifolia, D. beateae, and D. excelsa should be evaluated on the third day after sowing. The germination evaluations for D. excelsa and D. beateae should be carried out on the ninth day after sowing, and those for D. brevifolia on the sixth day after sowing.

Moringa oleiferaLam., known as moringa, is an arboreal plant belonging to the Moringaceae family, native to India,and has a high capacity to adapt to climatic conditions and arid soils. In this study we evaluated the initial development of seedlings of M. oleiferaLam. under different substrates conditions. The experiment was conducted in a completely randomized design, consisting of eight treatments resulting from combinations of the base substrate (85% soil, 3% carbonized rice straw and 12% coconut fiber). At 60 days after sowing, plant height, stem diameter, dry mass of the aerial part and root system, total dry mass were evaluated, in addition to the Dickson quality index (IQD). The best seedling growth occurred using the combination of 20% poultry litter and 10% bovine manure. Seedlings produced with substrates formulated with 20% poultry litter and 10% bovine manure showed gains in the evaluated variables, which could be a viable alternative for the production of moringa seedlings.

The forest soil is the main substrate in the production of ornamental plants in pots, but its unlimited extraction causes a negative environmental impact. One alternative for replacing the forest soil is the garden waste, also called “green waste”. The aim of this study was to characterize and determine the optimal dose inclusion of green waste in order to use it as substrate component for begonia (Begonia spp.) container cultivation. This experiment was performed in Morelos State, Mexico, in 2015. Physical and chemical laboratory analysis, as well as an agronomic evaluation was performed. Different proportions (100%, 75%, 50%, and 25%) of green waste and forest soil, supplemented by a general substrate (coconut fiber and sawdust, 50/50, v/v) were mixed. A completely randomized design of eight treatments with eight replications was used. Green waste has similar physicochemical characteristics to forest soil. In the growth and development of begonia plants, the results were statistically equal, between treatments of 100% green waste use and forest soil use in six of the sixteen variables studied, and was superior to other treatments, in one of them. As a result of this study, we reached the following conclusion: that green waste is a material that has the necessary physicochemical characteristics for the Begonia spp. container cultivation, and that if its used as a substrate, it could replace the forest soil.

ABSTRACT Ornamental plants are all plants grown for their beauty and are commonly used in gardening and landscaping. The colorful fruits and varied foliage colors that typify ornamental peppers provide a vibrant garden display that rivals other ornamental plants. This study aimed to evaluate the potential ornamental use of eight pepper accessions, Capsicum annuum, from the Capsicum Germplasm Bank of the Universidade Federal do Piauí, using qualitative and quantitative descriptors. The experiment was carried out in a greenhouse at the Department of Plant Science, Centre of Agricultural Sciences of Universidade Federal do Piauí, where the accessions were evaluated through a completely randomized design, with eight replicates, one plant per plot, and characterized based on 35 descriptors, 23 of which were qualitative and 12 quantitative. Data on quantitative descriptors were submitted to univariate analysis of variance, followed by Scott-Knott clustering test at 5% probability. Data on qualitative multicategorical descriptors were considered based on observations of statistical mode. The eight accessions evaluated have ornamental potential and are within the standards established by the Instituto Brasileiro de Floricultura. The accessions BAGC 98, 100, 203, 207, 224, and 236 accessions are suitable for cultivation in pots, while BAGC 220 is suitable for garden cultivation. BAGC 199 is the most promising accession because it supports all quality criteria required for size, foliage, flowers, and fruit proposed by the Veiling Holambra Cooperative.

The use of shading has been widely used for production of seedlings, flowers and ornamental plants, aiming to minimize the damage from the excess of luminosity. This research evaluated the effect of different shaded environments [0% (full sun); 35% and 50% of shading and overlapping screens of 35%+50%] on morphophysiological aspects and growth of Heliconia psittacorum cv. Golden Torch and Heliconia bihai cv. Humilis in Bom Jesus county, Piaui state, Brazil, from August, 2012 to July, 2013. The experiment was carried out in a completely randomized design with treatments arranged in a 2 x 4 (Species x Shading) factorial, with six repetitions. Plants of H. bihai cv. Humilis showed higher leaf area compared to H. psittacorum cv. Golden Torch when the corresponding overlapping screens of 35% + 50% was applied, indicating that the two species have different morphological mechanisms for adaptation in shaded environments. Plants grown in full sun (0% of shade) presented lower growth (height and leaf area) and lower chlorophyll content. The 50% of shading providedwas effective to achieve the desired establishment and growth of H. bihai cv. Humilis and H.Psittacorum cv. Golden Torch, grown in pots.

ABSTRACT Lisianthus is an important ornamental species, whose cultivation in pot still requires studies, mainly regarding the use of alternative management. Thus, the aim of this work was to evaluate the influence of resistance elicitors on the production and post-production quality of potted lisianthus. Plants grown in pots were treated with two elicitors: (E1) phosphorylated mannano-oligosaccharide and (E2) citric bioflavonoids and phytoalexins, in the doses (D) of 1 and 2pL.L-1 (E1D1 1pL.L-1, E1D2 2pL.L-1, E2D1 1pL.L-1, E2D2 2pL.L-1 and control), with 5 replications, in a completely randomized design. After opening the first flower buds, the plants remained in the greenhouse for 15 days, until they reached at least 3 open flowers, when were transferred to the room conditions (24 ± 2 oC and 72 ± 2%) for another 15 days. The application of elicitors did not influence the culture cycle or the size of the stem. There was an increase, however, in the number of viable buds and open flowers, in addition to an increase in flower’s useful life paralleled to the reduction of senescent flowers, in relation to the control. The dose of 2pL.L-1 of the E2 kept the percentage of viable open flowers in relation to the control for at least another 5 days, reducing the percentage of senescent flowers. Together, with the application of the E2 elicitor in potted lisianthus, the viability of the flowers can be prolonged, maintaining quality and delaying senescence, and, in this way, increasing the market period.
