Avaliação de diferentes substratos na qualidade fisiológica de sementes de melão de caroá [Sicana odorifera (Vell.) Naudim]

Caroa melon is a curcubitaceae found in its native form in the Reconcavo Region of Bahia, where it is used by popular medicine for many diseases. However, this species is little explored in research. The objective of the present work was to study different substrates in order to evaluate the germination index and seed vigor in caroa melon (Sicana odorifera) during seedling production. The following substrates were used: washed sand, sand washed with worm humus (2:1) and commercial substrate, Plantmax®.The following evaluations were carried out: germination test, speed of germination index (SGI), stem diameter, plant height, root length and root, stem and leaf dry matter. The commercial substrate Plantmax® presented the best performance compared to the others; however, the most adequate and least costly in seedling production using caroa melon (Sicana odorifera) seeds, was the mixture of washed sand and worm humus in the 2:1 ratio.

Avaliação do teor de óleo essencial de Baccharis trimera (Less.) DC. em diferentes embalagens durante o armazenamento

The use of medicinal plants as therapeutic source is ancient and has increased in value in recent years for both the population and the science. Several national and international companies use raw plant material in the preparation of their products, making essential the commercial cultivation and the post-harvest processing of these species. The aim of this study was to evaluate the essential oil content of [Baccharis trimera (Less.) DC.] in three different packages over one year of storage. During storage, Kraft-paper package best preserved the integrity of some physical and chemical characteristics of the product and maintained the oil content for one year of storage.

Produção de biomassa de erva-cidreira [Lippia alba (Mill.) N.E.Br.] sob adubação com composto de capim elefante inoculado e sem inoculação de actinomicetos

L. alba is a species of the family Verbenaceae widely used by the Brazilian population, because of the soothing, gentle antispasmodic, analgesic, expectorant, sedative, anxiolytic and smoothly. For the implementation of the experiment produced organic compound of elephant grass (Pennisetum purpureum Shum.) + manure at 70% plant material and 30% manure, uninoculated and inoculated with the actinomycete Streptomyces genus, AC16, AC26, AC92 and AC103. The compounds were placed in polyethylene bags containing 10.0 kg of soil added in a proportion equivalent to 20 t ha-1 and re-apply after the first harvest. The harvests of the shoots were taken at 75 and 165 days after transplantation. The roots were harvested after the second harvest. Dealing with organic fertilization promoted the average increase in biomass production of lemon grass 184, 83, 125, 115 and 122% for the dry stem biomass (MSPA) in the first harvest, second harvest of MSPA, total shoot biomass (MSTPA), dry biomass of the root (MSR) and the total crop biomass (MST), respectively, compared with the control, but no effect of inoculation of actinomycetes in compost. Under the conditions of this study was conducted, it was concluded that the organic compound fertilizer with elephant grass positively influenced the production of dry biomass of L. alba, but the injection of the compounds of the actinomycetes, without influence.

Desenvolvimento inicial de plantas de abobrinha italiana cultivada com húmus de minhoca

A abobrinha e uma das dez hortalicas mais cultivadas no Brasil. Possui alto valor nutricional e, por isso e utilizada como ingrediente principal na producao de tortas, doces e racao animal. Apesar da importância economica e nutricional, poucos sao os trabalhos envolvendo a adubacao e propagacao da cultura. Neste contexto, objetivou-se avaliar o efeito do humus de minhoca no desenvolvimento de plantas jovens de abobrinha. O experimento foi realizado durante os meses de novembro de 2012 a janeiro de 2013, em casa de vegetacao. O delineamento estatistico foi inteiramente casualizado, com seis tratamentos (0, 100, 200, 300, 400 e 1000 g de humus de minhoca por vaso de 1,5 L) e quatro repeticoes. As plantas cultivadas em 1000 g de humus de minhoca apresentaram maiores teores de massa seca da folha, caule e raiz. Pela analise de regressao, observou-se que a dosagem de 750 g foi a que permitiu os maximos valores de razao de area foliar e razao de peso foliar. Identificou-se relacao positiva entre a proporcao de humus e a massa seca de folhas+caule, massa seca da raiz e a massa seca total. Os teores de clorofila a e b foram maiores em doses de 575 e 644 g, respectivamente. Assim sendo, o uso de humus de minhoca favorece o desenvolvimento fisiologico de plantas jovens de abobrinha.
