“…Symptoms of mineral deficiency can affect different plant organs; in the case of ornamental plants, when these organs are the flowers, inflorescences or foliage, there is a significant impact on the quality of the final product, consequently affecting the final price thereof (FURTINI NETO et al, 2015). For plants fertilized with 0.5 g L -1 , a delay was observed in flowering, since no plant of this treatment presented open flowers, increasing the crop cycle.…”

“…Lack and excess of nutrients are detrimental to the quality of ornamental plants, since floriculture is a relatively recent activity when compared to other commercial crops, so the available literature on the mineral nutrition of ornamental plants is still scarce (FURTINI NETO et al, 2015). Therefore, the present work had as objective to evaluate nitrogen doses on the growth of potted Calceolaria x herbeohybrida Voss.…”

Calceolaria x herbeohybrida Voss (pocketbook plant, calceolaria) is an herbaceous perennial and floriferous species that can be grown in pots or beds. Nitrogen is usually the most required nutrient, being necessary to conduct studies in order to provide useful information for agronomic practices. Thus, this study aimed to evaluate nitrogen doses in the growth of Calceolaria x herbeohybrida in pots. Initially, assorted and pelleted calceolaria seeds were sow in multicellular trays containing a commercial substrate based on peat and kept in a floating irrigation system in a protected environment. At the greenhouse, seedlings with four true leaves were transplanted into 1 L pots containing the same substrate and a drip irrigation system. The treatments consisted of different nitrogen doses (0.0, 0.5, 1.0, 2.0 or 4.0 g of N L-1) applied weekly using ammonium nitrate as source. Fertilization with P and K was also done, and all treatments received de same dose. At the end of the experimental period, shoot length, leaf area, shoot and root dry matter, number of buds and flowers, chlorophyll a, b and total chlorophyll were evaluated. The experimental design was completely randomized with four replications and five plants per plot. The data were treated with ANOVA and the means were treated with regression analysis using the SigmaPlot 11.0 software. There was no survival of plants at the highest N dose (4.0 g L-1). Shoot length showed a quadratic behavior, with a maximum point at 1.25 g L-1, where plants reached 13.3 cm. There was a similar behavior for the variable leaf area, with the highest point at 1.24 g L-1. Shoot dry mass presented the maximum point at a dose of 1.20 g L-1, resulting in 4.21 g of dry matter. Regarding root dry matter, no equation could be adjusted. For the variable number of buds and flowers, the highest point was at a dose of 1.20 g L-1, with 35.86 buds and flowers per plant. For chlorophyll a, b and total chlorophyll, the maximum point was at 1.5 g L-1. The ideal nitrogen dose is between 1.2 and 1.5 g L-1 for most variables.

“…However, most producers use conventional fertilizers available in the market, which are developed with the aim to attend crops of food production (Takane, Yanagisawa, and Pivetta 2010). This results in high cultivation costs and products of poor quality, what explains the importance of knowing the species nutrition requirements (Furtini, Boldrin, and Mattson 2015).…”

Dendrobium nobile Lindl. is one of the most cultivated and distributed orchids around the world; however, information on its nutrition is scarce. Our objective was to study the plant development and nutrient accumulation in plants of D. nobile weekly fertilized with 100 mL Sarruge nutrient solution at 75% concentration. One plant per replication was randomly collected every month, along 12 months, totaling four plants. Dry matter (DM) and nutrient accumulation were determined for the different plant parts. Plants had already accumulated nearly 50% of total DM up to the flowering stage (240 days after first fertilization, DAFF). Order and amount of accumulated nutrients, at 360 DAFF, was, in mg per plant: K (701.07) > N (339.44) > Ca (289.03) > Mg (135.44) > P (118.83) > S (23.56); in mg per plant, it was Fe (14,122.35) > Zn (5,277.82) > Mn (3,216.87) > B (1,253.02) > Cu (271.25).

“…Thus, research is important to exploit such native species as new cultivation options. Compared to other commercial crops, floriculture is a relatively recent activity; thus, the information available on mineral nutrition required by ornamental plants is still limited (FURTINI NETO et al, 2015), and for cultivation of native species, the information is even more limited.…”

Angelonia integerrima is a native species that has ornamental potential, being cultivated in flowerbeds, flowerpots, pots, or even used as a complement in floral arrangements. Knowledge of mineral nutrition is required for the cultivation of the species, and slow release fertilization have become widespread in recent years, with a lower risk of toxicity to crops, an economy in relation to complementary fertilizers and may be an alternative to cultivation of potted plants. The aim of this study was to evaluate the development of Angelonia integerrima Sprengel in pot under slow release fertilization doses. Acclimatized seedlings with approximately 1 cm height, from in vitro germinated seeds were transplanted into 1 L pots containing substrate composted Pinus bark. Five doses of Basacote ® 9M slow release fertilizer, formulation 16-8-12 (N - P2O5 - K2O), 9 months: control - 0 g L-1, 2.5 g L-1, 5.0 g L-1, 7.5 g L-1 and 10.0 g L-1. The plants were grown in a greenhouse under drip irrigation. The shoot length, length of the largest inflorescence, number of stems, diameter of the largest stem, mean length of the stems, number of open flowers, fruits and senescent flowers, chlorophyll a, b and total, mass of dry matter of shoot and root system were evaluated after 286 days. The experimental design was completely randomized, with four replicates of six pots per plot. Data were submitted to analysis of variance (ANOVA) followed by polynomial regression by SigmaPlot 11.0. It was possible to adjust a quadratic equation for the variables: shoot length (with maximum response point in 7.2 g L-1), mean length of stems (6.7 g L-1), diameter of the largest stem and the root system (5.9 g L-1), number of open flowers, buds, senescent flowers and total flowers (7.7 g L-1). For the variables, number of stems, number of fruits, chlorophyll a, b and total did not differ between treatments. The slow releaser fertilizer indicated dose for the cultivation of the potted species is 7.2 g L-1.
