“…Furthermore, commercial substrates usually have some fertilizer added in the mixture. These results contrast those found by Assis et al (2011), which observed greater averages for coffee bark mixtures with coconut coir and carbonized rice husk in orchid cultivation. Table 3 presents the results of the emergence speed index.…”

The success of seedling production for ornamental or any other crops depends on several factors, including the use of highquality seeds and the choice of suitable substrates. The aim of this work was to evaluate the use of different organic residues as substrates and sowing depths on the emergence and initial development of pansy seedlings. Two lots of pansy seeds were used. Seed lot quality was evaluated for water content determination, 1000-seeds weight, germination, first count of germination, accelerated aging, seedling emergence in sand. Post emergence was evaluated by the emergence speed index, shoot length, shoot dry matter and number of leaves. The experiment was performed under completely randomized design, with four replicates. Data were submitted to analysis of variance through the F-test and the means, compared to each other by the Tukey test, at 5% probability. The most indicated sowing depths for the development of pansy seedlings were 1.5 and 2 cm while the substrate which presented the best results was the Beifort® S10.

Objetivou-se, com o trabalho, caracterizar as propriedades químicas e as composições dos substratos formulados à base de lodo de esgoto em diferentes combinações com resíduos orgânicos e vermiculita, a fim de se obter um meio de crescimento adequado para o crescimento de mudas florestais. Foi realizada análise de teores totais e disponíveis dos nutrientes dos 26 substratos formulados a partir da mistura de lodo de esgoto com vermiculita e os resíduos fibra de coco, palha de café in natura, composto orgânico, casca de arroz carbonizada e casca de arroz in natura, nas proporções de 100:0, 80:20, 60:40, 40:60 e 20:80 (lodo de esgoto:materiais) e uma testemunha, constituída por substrato comercial. O substrato comercial proporcionou as maiores médias para os teores disponíveis de fósforo, cálcio e magnésio. O lodo de esgoto proporcionou aumento da fertilidade dos substratos com aumento de teores de nutrientes, sobretudo fósforo, nitrogênio e cálcio. Os substratos formulados com lodo de esgoto e composto orgânico, independente de suas proporções, foram considerados os mais adequados para a produção de mudas de espécies florestais.

“…For commercial cultivation, using quality substrate, which supports the development of these flowering, becomes extremely important (Assis et al, 2010). However, orchids growth happens slowly (Suzuki et al, 2010), exposing the substrate for long periods to colonization by weeds such as Pilea microphylla (brilhantina), which affects seedlings development, increasing the cost of production and reducing their commercial value (Freitas et al, 2007b).…”

-Species of the orchidaceae family are grown for marketing flowers and among them the genus Cattleya stands out. However, due to its slow growth, the substrate is subjected to weed infestation. Therefore, this study aims to evaluate the selectivity and efficiency of herbicides in controlling Pilea microphylla in Cattleya orchid seedlings (Cattleya tenebrosa x Cattleya leopoldy). We used a completely randomized design with four replications. The evaluated herbicides were oxyfluorfen (0, 120, 240 and 480 g ha ) and metsulfuron-methyl (0, 1.2, 1.8 and 2.4 g ha -1). At post-emergence applying time, the Cattleya plants had three bulb sand were 10 cm tall, while P. microphylla, where 5 cm tall. Nicosulfuron, mesotrione and clethodim herbicides did not control P. microphylla, while oxyfluorfen and flumioxazin showed over 90% efficiency level sin controlling P. microphyllafrom 14 days after application (DAA). As to metsulfuron-methyl, it showed efficiency superior to 90% from the control dose of 1.8 g ha -1at 28 DAA. All herbicides were selective plants of Cattleya, however, only oxyfluorfen, flumioxazin and metsulfuronmethyl were effective in controlling P. microphylla.Keywords: weed, herbicide, floriculture, selectivity. ), flumioxazin (0, 12,5, 25 e 40 g ha -1 ), nicosulfuron (0, 20, 40 e 80 g ha -1 ), mesotrione (0, 96, 144 e 192 g ha -1 ), clethodim (0, 60, 84 e 108 g ha -1 ) e metsulfuron-methyl (0, 1,2, 1,8 RESUMO -Espécies da família
