The objective of this work was to evaluate the adaptation of anthurium (Anthurium andraeanum) cultivars as cut flowers in a subtropical area, located in north of Paraná State, Brazil. The Apalai, Ianomami, Kinã, nK 102, Parakanã, Rubi, and Terena cultivars were cultivated in a nursery under 80% shade. The number of leaves and inflorescences, floral stem length, length and width of inflorescences, and spadix length were evaluated. The experimental design was in completely randomized blocks, with six replicates and five plants per plot. During the 18 months evaluated, 'Parakanã' produced 11 inflorescences per plant, whereas the other cultivars produced seven to nine inflorescences per plant. The number of leaves produced per plant was: 'Ianomami', 25; 'Parakanã', 20; 'Apalai' and 'Terena', 15; 'Kinã' and 'Rubi', 11; and 'nK 102', 9. The Apalai, nK 102, Parakanã, and Rubi cultivars are the most recommended as cut flowers; the Ianomami cultivar is not recommended as a cut flower in this region.

Several cut flower species were studied to determine their feasibility for cut flower production. Three fertilizer treatments (0.5, .1, and .15kg/m2 respectively) were used and their effect on number of stems, stem length and fresh weight were determined. Celosia cristata and Ageratum houstonianum `Blue Horizon' proved to respond best to fertilizer treatments. Celosia fertilized at a rate of .15kg/m2 will produce approximately 200 stems/m2. Ageratum will produce appoximately 400 stems/m2 when fertilized at a rate of .10kg/m2. Fertlizer rates of .10 and .15 kg/m2 for Eustoma culture yielded 86 stems/m2, which was lower than other species used in this test. Extended vase life and consumer response could possibly justify using this species in cut flower production. An economic break-even analysis will be presented to show what price will have to be received per stem to cover costs.

The objective of this study was to verify levels of shade and doses of earthworm humus in the production of Lactuca canadensis L. seedlings.  The experimental design was completely randomized in a 4 x 5 factorial scheme (four levels of shade and five doses of humus).  The different levels were obtained using black polyethylene screen with 35, 50 and 70% shade and in full sun. The substrates were obtained by mixing commercial substrate for vegetables (Vivatto Slim ® plus), with earthworm humus in the proportions of 0, 15, 30, 45 and 60%.  There was no seedlings emergence in the full sun and, the treatment with 50% of shade allows the best development. The substrate without humus and with 60% presented superior results but the higher dose stood out for number of leaves (3.14) and chlorophyll content (32.9%), in 50% of shade. For the other variables, there was no difference between the commercial substrate and 60% of humus, so the commercial substrate can be used in the production of Lactuca canadensis L. seedlings, considering the ratio benefit/cost ratio.

The objective of this study was to evaluate the effect of nitrogen and potassium silicate on the production and commercial aspects of curly lettuce, Vera cultivar. The experimental design was completely randomized (CRD), with ten treatments and three replications. The treatments, arranged in a factorial design according to the Plan Puebla III matrix (Turrent & Laird, 1975), consisted of the combination of five doses of nitrogen (9; 54; 90; 126, and 171 kg ha-1) and five doses of potassium silicate (1.15; 6.90; 11.50; 16.10, and 21.85 kg ha-1). A control treatment without application of nitrogen and potassium silicate was also inserted. The crop was grown in a greenhouse, and the doses were applied as sidedressing using a drip micro-irrigation system. Total fresh matter, commercial fresh matter, non-commercial fresh matter, number of leaves and commercial trade index were evaluated. The commercial fresh matter and the number of commercial leaves per plant were affected only by nitrogen fertigation and increased linearly with an increase in the dose of nitrogen, with the best responses observed at the highest dose of this element (171 kg ha-1). Potassium silicate only had an effect on non-commercial fresh matter, with no influence on the other characteristics.

Gibberellic acid (GA3) induces flowering of plants of various genera of the Araceae family. Therefore, it was evaluated the effect of GA3 on the growth and yield of Anthurium andraeanum cv. 'Apalai'. For this purpose, micropropagated seedlings were planted in nursery beds under 70% shade. The experimental design was completely randomized in subdivided plots with eight replications. The growth regulation effect was assessed in each plot and the time to flowering after the start of the treatments was assessed in each subplot. The GA3 concentrations were 0, 150, 300, 450 and 600mg L-1, applied every 60 days by spraying on the leaves. The applications and evaluations started after the production of marketable floral stems. Every month the number of leaves was counted and their dimensions were measured, while every week the presence of inflorescences and the point of their commercial harvest were assessed and the respective dimensions were measured. Application of GA3 at 150, 300 and 450 mg L-1 promoted an increase in the leaf area. However, there was no increase in the number of inflorescences produced or their quality, making it impossible to recommend the use of this growth regulator for commercial production of this flower.

This study aimed to evaluate the performance of 'Feizixiao', 'Nuomici', 'Heiye', 'Kway May Pink' and 'Bengal' lychee cultivars topworked onto bearing 'Bengal' trees. The experiments were carried out in commercial orchard at Rio das Pedras Farm in Jundiaí, state of São Paulo. The experimental design consisted of randomized blocks in a subdivided parcel arrangement, in which the parcel consisted of five cultivars and the sub-parcel consisted of six evaluation periods. Five replicates of three plants per parcel and six grafts per plant, (with two grafts per main branch) were used. The trees were approximately 10 years old propagated by air layering and planted with 6 x 4 m (416 plants/ha) spacing. The following characteristics were evaluated: success rate of the grafts, number of shoots, shoot length, number of nodes, number of leaves and chlorophyll content (SPAD). The control ('Bengal'/'Bengal') had the highest grafting success rate with 89.9%. On the other hand, 'Heiye', 'Feizixião', 'Nuomici' and 'Kway May Pink' had, respectively, 60.6, 55.0, 52.6 and 47.0% grafting success rates. All of the shoot grafts had normal growth with no signs of incompatibility. Therefore, the cultivars studied are compatible with 'Bengal' and may be used on commercial orchards.

This study was conducted to find out the effect of fertilizers on the performance of two hybrids of Euphorbia as indicated by growth and flowering performance. The experimental design with controlled variables was used in the study. The use of organic fertilizers like the use of animal dungs or wastes was proven effective based on the different trials made. In terms of the effect of the fertilizers in the growth performance, there were significant differences on plant height, stem girth, number of leaves, and number of shoots during the 20th, 50th and 80th days of observations. The number of flowers was found to have significant differences in all stages. When measured during the 80th day of observation, significant differences were shown in the size of flowers. However, insignificant difference was shown in the diameter of flower bracts. As to the growth parameters, carabao manure yielded more leaves, and shoots and taller Euphorbia Orchid. It also produced bigger stem girths, wider and longer leaf sizes of Siam Ruby hybrid. As to flowering parameters, carabao manure influenced the growth of more number of flower clusters and bigger sizes of flowers of Euphorbia Orchid. On the other hand, chicken manure also influenced the growth of more number of flowers per cluster of Siam Ruby during the 50th day observation and carabao manure during the 20th day observation.

ABSTRACT Lettuce seedlings used on hydroponic cultivation (NFT) are usually produced in trays with small volume, requiring two transplants: from tray to nursery and then to the definitive place. The aim of this study was to verify lettuce performance under NFT system, using seedlings produced in trays with several cell volumes (50, 40, 35, 31, 30, 29, 27, 20 and 10 cm³ cell-1). The tray volumes are considered treatments. The experimental design was completely randomized blocks, with four replicates. Seedlings were transplanted directly to the definitive profile, except those ones produced in 10 cm³ cell-1. Two harvests were performed, at 22 and 29 days after transplant (DAT). We evaluated number of senescent leaves, total number of leaves, shoot fresh mass, root fresh mass, shoot dry mass, stem length and productivity. The best performance was obtained using seedlings produced in trays with higher volume per cell. The nursery phase was not necessary and it was possible to obtain reduction from two to one transplant, corresponding to trays of 20 to 50 cm³ cell-1. Seedlings produced in trays with 40 and 50 cm³ cell-1 made the early harvest possible, at 22 DAT of cultivation under hydroponic NFT system.

The stems of many flower species used as cut flowers are too short to be commercially useful. Non-chemical techniques are needed to increase the length of the harvested stems without weakening stem strength. Field experiments were conducted that explored the use of black or red shade fabric, used either as a canopy, or as a side curtain, with three species of cut flowers. Trachelium caerulum, Eustoma grandiflorum (Echo Champagne), and Rudbeckia hirta (Prairie Sun) were grown in split-plot experiments in which shade and shelter treatments were applied as main plots, and the flower species formed the subplots. In 2004, shade canopies of 70% light transmission were compared in black and red (“ChromatiNet”) netting, and 50% red netting. Stem length increased from 51 cm for unshaded controls to 54, 56, and 59 cm for 70% black, red, and 50% red, respectively. Productivity of the plants was decreased an average of 21% by shading. In 2005, shade canopies of 50% black or red were compared to side curtains of the same materials, and an unsheltered control, growing the same species of flowers. Stem length was increased by 25% when plants were grown under a shade canopy, and by 14% in the side curtain plots. Shading treatments reduced stem yield by 31%, whereas side curtains had no significant effect on number of stems per plant. Color of the netting did not affect stem length or stem yield in 2005. In both years, the thickness of harvested stems were increased significantly in the shelter treatments. The three species reacted similarly to the treatments imposed in both years. Shelter treatments can be a practical way of increasing cut flower stem length.

The effect of a brief exposure to treatments of end-of-day (EOD) far-red (FR) light and EOD-heating on flowering and stem elongation in certain species cultivated in areas with limited sunshine from autumn to winter has been investigated. Thirteen EOD-FR treated cultivars among all 24 cultivars tested in experiment 1, showed earlier flowering than control plants. Additionally, Kanzaki No.21, F1 Winter cherry and Gypsy deep rose were earlier to flower under the all night-FR treatment than under the EOD-FR treatment. Further, 13 cultivars among all cultivars tested in experiment 1 showed greater stem length, whereas 16 cultivars of them showed greater mean internode length than controls when treated with EOD-FR. The days to flowering in 13 cultivars treated by EOD-Heating, flowering was earlier than in controls. Also, stem length and mean internode length were also promoted by the same treatment in 7 cultivars. Additionally, flowering and stem elongation of Stella rose, Arizona sun, Suzuhime and Extra carmine rose were promoted by a combination of both treatments, and productivity and quality were improved. These results suggest that the treatments tested can help the production of cut-flowers in areas with limited sunshine from autumn to winter, although the method of application of the treatments must be optimized for each species.
