title: Micropropagation of lavender: a protocol for production of plantlets

description: ABSTRACT Lavender (Lavandula dentata) has several medicinal applications, both in the fresh form and after industrial processing. Productivity increase could be obtained through the mass propagation, expanding the possibility of obtaining raw material for production of essential oil. The objective of this work was to develop a micropropagation protocol from explants obtained from seeds. Aspects of in vitro germination, multiplication, elongation and rooting were evaluated and, in sequence, the acclimatization process as well. The in vitro germination of lavender seeds can be obtained using a medium composed of agar and water. For multiplication, the use of MS medium (Murashige & Skoog, 1962) added with 5.0 µM 6-benzylaminopurine to the nutrient medium is the most appropriate. For elongation and rooting, the use of growth regulators is unnecessary. Acclimatization can be obtained directly by transferring the explant to plastic bags with substrate, kept in a greenhouse. It was possible to develop a protocol for the in vitro cultivation (establishment, multiplication, elongation, rooting and acclimatization) of lavender from explants of seed origin.

title: Post-harvest quality and sensory acceptance of Italian tomatoes grown under organic, integrated and conventional management

description: ABSTRACT Some studies comparing the quality of tomatoes under organic and conventional management can be found in literature; they are still inconclusive and many of them do not address integrated management, though. The aim of this study was to evaluate physical, biochemical and sensory traits of Italian tomatoes under organic, conventional and Hightech integrated managements. Physical (firmness, length, width, mesocarp thickness, mass and volume) and biochemical traits (titratable acidity, sugar content, soluble solids content, vitamin C content, lycopene content, beta-carotene content and antioxidant capacity) were evaluated, besides the sensory attributes as appearance, aroma, flavor and texture evaluated by 105 consumers. The organic fruits showed greater width, fresh mass and pericarp thickness, glucose and vitamin C. The fruits grown under integrated management stood out for higher levels of beta-carotene, whereas the fruits grown under conventional management showed greater acidity and higher lycopene content, as well as less firmness. No difference in relation to the acceptance of tomatoes under the different managements used was noticed, although most consumers preferred organic tomatoes, which were the largest and sweetest. No difference in relation to the acceptance of tomatoes produced under different managements was noticed, despite the discrimination in physical and biochemical traits. Hence, the managements affected only the physical and biochemical traits of Italian tomatoes.

title: Firmness and biochemical composition of Shitake and Shimeji commercialized in natura and consumers' opinion survey

description: ABSTRACT Mushroom production has been growing in Brazil due to the culinary versatility of this food and its high nutritional value. However, few studies associating the aspects of its quality with the profile and preference of its consumers can be found in literature. Thus, in this study, we aimed to evaluate the firmness and biochemical composition of Shimeji and Shitake, as well as, the consumers’ profile and preference for purchasing these mushrooms. The mushrooms were characterized by firmness, protein and lipid content, total phenolic compounds, total flavonoids and antioxidation activity. In addition we carried out a survey on opinion of 308 mushroom consumers. The two mushrooms contain high protein content and low lipid content, and also expressive concentrations of bioactive compounds and antioxidant activity, suitable for these demanding functional food consumers. Shitake is approximately 4 times firmer than Shimeji and the highest levels for all analyzed biochemical attributes did not differ between the two studied mushrooms, except for protein content. The opinion survey indicated that young and adult women consume more mushrooms than men. Most of them buy mushrooms in supermarkets, and they are mostly higher educated people. No significant higher consumer preference for one of the two mushrooms analyzed was verified; however, most participants reported that they prioritize mushrooms which have characteristic aroma and flavor, smooth and juicy texture, being a convenient ingredient for a quick-cooking meal.

title: Productivity of lettuce in greenhouse as affected by humic and fulvic acids application in association to mineral fertilizer

description: ABSTRACT Humic substances (HS) have proved to be effective in improving the productivity of vegetable crops. We examined the effect of commercial biostimulants rich in humic (HA) and fulvic acids (FA) obtained from leonardite on agronomic efficiency and nutrient content in the leaves of lettuce (Lactuca sativa). A greenhouse experiment was carried out employing 2.5-L pots containing Ultisol samples that were supplied with commercial biostimulants rich in HA and FA, alone and in combination with NPK mineral fertilizer. The application of HS biostimulants associated to mineral fertilization to the lettuce plants provided the greatest values of the studied variables, namely: plant height and diameter, leaf number per plant and root length. The combination of FA biostimulants and mineral fertilization increased the lettuce productivity relative to the inorganic fertilizer alone. The combined application of rich biostimulants FA and HA with NPK fertilizes influenced K and Fe uptake by the plants, and their accumulation in the aerial portion. Our results suggest that HS products potentialize the nutritional effect of the mineral fertilizer, when applied in combination.

title: Beet-arugula intercropping under green manuring and planting density induce to agro-economic advantages

description: ABSTRACT One of the biggest challenges in the intercropping system of two crops is to obtain the optimal dose of green manure and the adequate population density of the crops. So, the objective of this work was to evaluate the performance of beet and arugula intercropping, influenced by green manuring with Merremia aegyptia and Calotropis procera and arugula population densities in two cultivation years, in semi-arid environment. The experimental design used was in randomized complete blocks, with the treatments arranged in a 4 x 4 factorial scheme, with 4 repetitions. The first factor of this scheme consisted of equitable amounts of M. aegyptia and C. procera biomass (20, 35, 50 and 65 t ha-1 on a dry basis) and the second factor, by arugula population densities (40, 60, 80 and 100% of the recommended density for single cropping, corresponding to 400, 600, 800 and 1,000 thousand arugula plants ha-1). The production and its components were evaluated on beet and arugula. In addition to these characteristics, the following agro-economic indicators were also determined for each treatment: system productivity index (SPI), land equivalent coefficient (LEC) and monetary equivalent ratio (MER). The greatest agro-economic advantages of the beet with arugula intercropping were achieved with a system productivity index (SPI) of 53.47 t ha-1, land equivalent coefficient (LEC) of 0.84 and a monetary equivalent ratio (MER) of 1.56, respectively, combining 65 t ha-1 of M. aegyptia and C. procera biomass with the arugula population density of 1,000 thousand plants ha-1. The maximum optimized commercial productivity of beetroots in the system intercropped with arugula was 23.20 t ha-1 using 65 t ha-1 of M. aegyptia and C. procera and in the arugula population density of 1,000 thousand plants ha-1, while the maximum arugula productivity intercropped with beet was 9.65 t ha-1, in the same combination of green manures amount and arugula population density.

title: Pircinque: new strawberry cultivar for Brazilian producers

description: ABSTRACT The strawberry cultivar ‘Pircinque’ was developed by the breeding program of Consiglio per la Ricerca in Agricoltura e l’Analisi dell’Economia Agraria - Centro di Olivicoltura, Frutticoltura e Agrumicoltura (CREA-OFA-FRF), an Italian research entity, and introduced in Brazil in 2013 by the Centro de Ciências Agroveterinárias da Universidade do Estado de Santa Catarina (CAV-UDESC). In the breeding program in which it originated, ‘Pircinque’ was selected for plant rusticity and resistance to soil pathogens. It can be cultivated where soil sterilization techniques are not used. In Brazil, the cultivation of ‘Pircinque’ has shown to be promising in the major strawberry producing regions. The main characteristics that allowed the development of this cultivar among the growers were plant vigor, productivity, rusticity, flavor, pulp firmness, crispness, sweetness and fruit color. When grown with excessive nitrogen fertilization fruit sensitivity to Botrytis cinerea fungal attack has been found, and a high vegetative plant growth. Due to fruits peculiarity, many growers make differentiated sales, adding value to quality product. Also, due to the high post-harvest period, many growers allocate part of the production to more distant locations. These characteristics are determinant for the cultivar Pircinque be distinguishable from other strawberry cultivars already marketed in Brazil. The cultivar was registered at the Ministério da Agricultura, Pecuária e Abastecimento (MAPA) in 2016, and the commercialization of plants started in 2017 with five nurseries accredited to produce and market ‘Pircinque’ plants throughout Brazil.

title: Relationship between bud number in seed branches and yield aspects of sweet potato

description: ABSTRACT Planting sweet potato branches with the appropriate bud number and disposition, below and above ground, can favor vegetative growth and yield that better fit the marketable standards. This study aimed to explore the influence of the number of buds and their distribution ratio, above and below ground level, on the agronomic and marketable components of sweet potato tuberous roots. The experiment was carried out in a randomized complete block design with three replications. The treatments were arranged in a factorial scheme (3 x 5), with 2, 4, and 8 above-ground buds combined with 2, 4, 6, 8, and 10 below-ground buds. Branches from the UZBD 06 accession (Canadense standard) were used. Vegetative, productive, and marketable traits of roots were evaluated. The use of branches with a greater number of buds above and below ground increased shoot dry biomass. Planting seed branches with 8 buds above and 8 buds below ground provided a greater number and production of marketable roots. The use of 10 buried buds increased root number and yield in the 150-450 g marketable classes, which the consumer market values the most.
