Avaliação do crescimento e uso paisagístico de coração-magoado (Solenostemon scutellarioides L. Codd, Lamiaceae-Lamiales)

Abstract

The Brazilian floriculture has been a fertile ground for agribusiness. Still, Brazilian exports of flowers and ornamental plants still have values below that are generated internationally by major countries active in the sector. One reason of imports in Brazil are high, it is precisely the lack of trained personnel to work in the activity. Even with the growth in research, automation; there is still the need to use specialized hand labor mainly in the post-harvest treatment, since it is a delicate material nature. The international market of Floriculture is also characterized by the frequent release of new plants to meet the consumer interest in colors and different shapes. In this ornamental trade there is a great demand for foliage and complemented for the ornamental sector with cut flowers. The lack of new products in this line has been worldwide. The lack of new products in this line has been worldwide. Thus, the aim of this study was to evaluate the growth of Solenostemon scutellarioides species known as coleus, emphasizing its role as ornamental cut foliage. The work was divided into stages: 1) was first made the planting of 30 stakes 7cm in vessels with volume 500dm³ to obtain seedlings and development of a framework for notes visual assessment of the following experiments. 2) After growth, the cutting rods 30 are held, where 10 were placed in water at 10 Salicylic acid (10mM) and 10 in the refrigerator for observation for conservation and storage. 3) with the rods which remained in the vessel, it is regeneration by growth analysis: measurement of the diameter, number of leaves, leaf area, plant height. 4) was then done two tests compared to 10 rods in the refrigerator, and 5 in sealed plastic bag with a damp paper towel and plastic bag 5 with no paper towels. 5) to finish was made to light compared with 6 vessels each treatment: shade, partial shade and full sun. Data were released in Excel 2016, there was analysis of variance (ANOVA), Tukey 5% and Kruskal-Wallis. For number of sheets, height, diameter and leaf area results were significant according to the time; where growth occurred more rapidly during the early regeneration. As for the storage experiment and Conservation (item 2), there was a statistically significant difference, where the stems placed in water and cooling are statistically equal, but different from the rods in salicylic acid, and the note of this is smaller than the other. In the experiment with cooling (item 4) and experiment with light (item 5), it was not observed 5% statistical significance. It was therefore concluded that the Solenostemon scutellarioides species, has rapid regeneration with satisfactory development, being a species with good adaptation indoors and open, l and good conservation in water and can be used in landscaping and ornamental flower arrangements.
