“…The plant root system plays an important role in the interactions between the soil and the banana crop, and knowledge regarding its distribution in the soil allows better use of cultivation practices, such as irrigation management (Coelho, Oliveira, Araújo, Vasconcelos, & Lima, 2001;Fracaro, & Pereira, 2004).…”

ABSTRACT. This study aimed to evaluate the effects of fertigation with humic substances, with and without the addition of plant extracts, on the root system of the 'BRS Princesa' banana cultivar. The banana crop was cultivated at a spacing of 2.0 x 2.5 m and fertigated using a drip system in a dystrocohesive Yellow Latosol. The experimental design was randomized blocks, in a split-split-plot scheme with five replicates, for the following factors: humic substance doses and presence of a plant extract formulation. The treatments consisted of five doses of humic substances, based on a reference dose of 14.14 L ha , in the presence and absence of plant extract. The variable root length (cm) was subjected to variance analyses to evaluate the effect of the humic substances, either isolated or in interaction with plant extract and soil depth. The use of the plant extract increased the effect of the humic substance on root length but overshadowed its effect for the different doses of humic substance. Root length was not sensitive to increasing humic substance dose with plant extract for doses of up to 42.42 L ha -1 at 0 -0.40 m depth.

“…The higher stem diameter in the initial phase may provide a high accumulation of sucrose together with the greater volume of tissues developed, which can be explained by [26], stating that the emergence of the first tillering and its development in diameter is related to the size of the stem and thickness of the original stem. Studies conducted in vines by [27] have observed that the use of ethephon applied via foliar has become effective in the growth and increase in the diameter of branches.…”

The hormones are closely related to the emergence of gemstones contained seedlings of sugarcane, at the time of planting of the stems. The objective of this work was to evaluate the effects of the ethephon associated with the position of gemstones in the cane of sugar cane in the initial development of the culture. In March 2014, at the Rio Vermelho Plant, located in Junqueirópolis, State of São Paulo, a cane plant with a sugar cane plant was selected for seedlings with an approximate age of 11 months. Two areas with dimensions of 20x20 meters were demarcated. In one of the areas, ethephon was applied. At 15 days after application, the seedlings containing 1 and 2 buds were collected to compose two independent experiments. From the area where the product was not applied, seedlings were removed for the control and application treatments of Ethephon in the planting groove in pots. The gems were sent to the Faculty of Agrarian and Technological Sciences of the Paulista State University "Júlio de Mesquita Filho" - from Dracena, State of São Paulo. The seedlings came from the apex, middle and base of the canes of sugarcane. In this way, the experimental design was in a 3x3 factorial scheme, that is, the position of the seedlings in the canes of sugarcane and the modes of application of ethephon. The use of ethephon in the plant 15 days before planting together with seedlings from the sugar cane culms showed the best results for the rate of emergence; a number of tillers; dry matter weight of stem and leaves and leaf area.

“…Estudos que avaliaram o uso do etileno demonstraram sua influência em muitos processos fisiológicos das plantas. O etefon, princípio ativo utilizado em experimentos, mostrou-se eficiente no aumento do número de brotação de gemas e, em aplicações sucessivas em videiras, provocam o aumento da fertilidade e do estímulo de brotação de gemas, aumentando a produtividade (ALBUQUERQUE, DANTAS, 2002;FRACARO et al 2004). Além disso, a aplicação foliar de etefon pode influenciar o aumento, o crescimento e o diâmetro de ramos em videiras (FRACARO, PEREIRA, 2004) e, ainda, no aumento, comprimento e peso dos cachos.…”

“…O etefon é utilizado para aumentar a coloração de bagas, mas seu efeito não é consistente, podendo provocar o amolecimento da baga (PEPPI et al 2007). Em videiras, influencia no aumento da fertilidade aumentando a produtividade, também sendo eficaz no aumento do crescimento e diâmetro dos ramos e no aumento do comprimento, largura e peso dos cachos (FRACARO, PEREIRA, 2004).…”

O livro, com 21 capítulos reunindo inúmeros autores de renomada experiência, traz uma infinidade de informações, fruto de extensas revisões e principalmente obtidas através de densos projetos de pesquisa desenvolvidos pelas principais instituições públicas, capitaneada pela UDESC, em parceria com produtores individuais ou associados, localizados na Região de Altitude mais tradicional na produção de uvas de Santa Catarina. A identificação das melhores cultivares e as possíveis combinações de porta-enxertos, a definição do manejo do dossel, a carga de gemas, o manejo da poda e os sistemas de condução para cada situação, aliados a todas as questões relativas ao manejo o solo, da nutrição e adubação e a delicada e complexa questão da fitossanidade, chegando na colheita e processamento, entre outros, exemplifica a importância de todos capítulos desse grande livro.
