ABSTRACT The rootstock Poncirus trifoliata var. monstrosa flying dragon (FD) induces dwarfism to citrus trees. Dwarfism provides several positive aspects: allows dense planting, reduces the pruning frequency, improves productivity efficiency, and makes cultural practices easier. Evaluating compatibility of with different scion varieties is crucial for recommending this requires many years field observations. aim investigation was evaluate vigor graft Citrus × sinensis L. Osbeck latifolia...
A citricultura brasileira desempenha um papel crucial na economia nacional. Pomares didáticos são necessários para respaldar o aprendizado teórico, e fortalecer habilidades práticas. Este estudo demonstra a importância de pomar didático formação dos alunos extensão rural, com ênfase prática enxertia. Variedades copa porta-enxertos foram catalogadas documentadas em citros, identificação das plantas vinculação destas códigos QR, estes site informações detalhadas sobre essas plantas. Visitas...
A produção de mudas é fundamental para o sucesso da implementação pomares goiabeira (Psidium guajava L.), especialmente na agricultura familiar, onde a cultura se destaca pela geração renda e segurança alimentar. Este trabalho relata experiência um curso extensão universitária realizado no Norte Fluminense, com objetivo capacitar pequenos produtores estudantes sustentável goiabeira. Foram abordadas técnicas propagação, uso tecnologias como câmaras nebulização sistemas caseiros acessíveis...
ABSTRACT Guava rootstocks can be multiplied by minicuttings in environment with a high relative humidity, being necessary an acclimatization period. Certain growth regulators favor the acclimatization, brassinosteroids successfully used other fruit plants. This study aimed to shorten multiplication time of BRS Guaraçá hybrid applying Biobras-16 (BB-16) during seedlings obtained from minicuttings. The treatments consisted five BB-16 concentrations (0, 0.1, 0.3, 0.5 and 1.0 mg L-1), applied...
One of the obstacles to arboreal plant breeding is time required between selection superior genotypes and their multiplication. This study investigates Psidium (guava) hybrids developed obtain rootstock or new scions resistant nematode Meloidogyne enterolobii. The use half-siblings hybrid seeds these genetic materials does not preserve profile individuals, making destructive methods unfeasible. Propagating juvenile material by minicutting produces a high rooting percentage, facilitating...
The viability of the mini-cutting technique requires seedling regrowth ability and continuous propagule production. It is hypothesized that application gibberellic acid (GA) can stimulate vegetation increase production mini-cuttings. aim this study was to yield Psidium guajava (L.) × guineense (Sw.) (‘BRS Guaraçá’) as a function foliar GA season year. experiment laid out in randomized-block design with split-plots time, which plots consisted different concentrations applied (0, 50, 100, 150...
Brazil has a range of fruit species, especially native ones, which play an important role in the life local populations, but are still little studied, as is case bacuri (Platonia insignis Mart.). P. tree species from Amazon region and great economic potential, mainly due to its excellent organoleptic nutritional characteristics. Therefore, there need for research that seeks proper use well selection superior genotypes. Thus, objective this study was characterize biometric chemically fruits...
Abstract The production of grafted seedlings requires longer periods time. technique mini-grafting onto rootstocks previously obtained from herbaceous cuttings can guarantee the genetic fidelity scion and rootstock allows grafting smaller-diameter stems, accelerating time required to obtain seedlings. aim this study was anticipate formation ‘Paluma’ guava clonal with stems. Treatments consisted five stem diameter classes. experimental design randomised blocks three replicates per plot....
Changes in the structure of vegetation reflect on biodiversity and dynamics ecosystem. The objective study was to characterize compare fragments with occurrence Platonia insiginis, different stages regeneration, 6, 10, 25 100 years fallow period western Brazilian Amazon. conducted a completely randomized design, four treatments, consisting period, five replications, demarcated temporary plots for each dimensions 2 m x regenerating stratum 10 adult vegetation. Phytosociological parameters...
