A serapilheira de matas e florestas é rica em matéria orgânica e responsável pela ciclagem de nutrientes que ocorre neste ecossistema. Além de atuar como protetora do solo e habitat para diversos microrganismos e insetos. O presente estudo buscou analisar o papel da serapilheira no desenvolvimento de mudas florestais nativas em viveiros. As espécies utilizadas no experimento foram Parapitadenia rigida (Benth) (angico-vermelho), Acacia polyphylla DC. (monjoleiro), Lonchocarpus muehlbergianus Hassl. (embira-de-sapo) e Schizolobium parahyba (Vell.)S.F.Blake (guapuruvu). O crescimento foi analisado em quatro substratos: mineral (S1), mineral com serapilheira na proporção de volume 1:1 (S2), orgânico usado em viveiros (S3) e orgânico usado em viveiros com serapilheira na proporção de volume 1:1 (S4). O delineamento experimental consistiu em blocos ao acaso com 16 tratamentos e 5 repetições. Durante uma primeira fase foram feitas as medições de altura e diâmetro das mudas em fase de viveiro. A segunda fase foi a análise da biomassa seca e avaliação da sobrevivência inicial em campo. O resultado apresentou melhores desempenhos no crescimento e sobrevivência nos tratamentos com serapilheira em comparação aos sem serapilheira. Podemos concluir que a serapilheira apresenta potenciais benéficos relevantes para a produção de mudas florestais

Trade seedlings without certification contributed to spread pests and diseases which can cause a large damage to grown plants. In Itapetininga (SP), was seized by Agricultural Defense staff, seedlings of barbados cherry, guava and mulberry, sold in trucks, all of that had galls on roots, typical symptom caused by Meloidogyne spp. Specie identification was made by morphology of female perineal pattern and male head, as well as characterization of esterase enzyme phenotype. It was confirmed the presence of M. enterolobii in the samples analyzed. This is the first report of M. enterolobii in mulberry seedlings in the world.

The physic nut can be propagated asexually or sexually. Using cuttings have been earlier yield and more fidelity characteristics of the parent plant. However, there is less initial vegetative growth. The seeds from the plants have increased genetic variability, are more vigorous and begin production later. To get quality changes, the substrate is an important factor. With that the objective was to taste pre-germinated treatments and different substrate on seeds emergence and quality physic nut seedlings. The experimental design was completely randomized, in factorial scheme 6 x 3 (pre-germinated treatments x substrate), 18 treatments and 4 repetition, 8 seeds to each repetition. It was evaluated six pre-germination treatments: T1: witness (without treatments); T2: water immersion for 12 hours; T3: water immersion for 24 hours; T4: mechanical scarification; T5: mechanical scarification + water immersion for 12 hours; T6: mechanical scarification + water immersion for 24 hours, using as substrate: commercial, expanded vermiculite and sand washed. The mechanical scarification was realized opposite the micropyle using sandpaper n. 60. After the pre-germination treatments, the seeds were emergence in plastic cups (200mL) with substrates. We evaluated the characteristics: percentage, beginning and emergence speed index, mean length of plant, diameter of plant stem, SPAD index, fresh and dry shoot and root. The results showed that in seeds of Jatropha do not need pre-germinative treatments; and the use of commercial substrate showed seedling development.

The objective of this work was to evaluate the effects of the inoculation with plant growth-promoting bacteria on the formation of sugarcane pre-sprouted seedlings, originated from individual buds, and to quantify the initial growth of these seedlings in association with nitrogen application, in a low fertility soil. Two experiments were carried out: one in greenhouse conditions, with a time span of 50 days, and the other in vases under field conditions, with a time span of 180 days. In both experiments, a randomized complete block design was used with a factorial arrangement of 2x3, in the first experiment - with or without inoculation, and with three quantities of bud reserve -, and of 2x2x4, in the second one - with or without inoculation, with or without nitrogen, evaluated in four times: at 45, 90, 135, and 180 days. The inoculant had effect on the initial growth of the pre-sprouted seedlings, increasing sprouting speed and dry matter accumulation on roots and shoots, regardless of the bud reserve amount. In the second experiment, the inoculant increased the initial growth of shoots and root system up to 180 days after transplantation, increasing height, tillering, stalk diameter, dry matter production of stalks and straw, and root length, regardless of nitrogen application. The inoculant has a positive physiological effect on plant growth.
