A quantitative assessment of factors affecting the rooting of grapevine rootsto...

Grapevine is a fruit species of great agronomic interest since both fresh fruit and wine are highly marketable products. Therefore, there is growing interest in this crop among researchers in the pursuit of increased yields and better cultivation conditions. Asexual propagation is the most commonly used method for propagating grapevine seedlings, with cuttings used for rootstock formation and subsequent graftin...

Rooting of Brazilian coral as a function of cutting types and season of the year

Erythrina falcata Benth. may be used as an ornamental plant, in rehabilitation of degraded land and as a component in agroforestry systems. However seedling production from seeds is difficult. The aim of this work was to evaluate vegetative propagation of E. falcata by using stem cuttings obtained from adult trees (softwood cuttings, hardwood cuttings and regrowth cuttings) and cuttings from seedlings collected...

Renewable substrates in the production of Ficus enormis seedlings from clonal g...

We aimed to assess the use of renewable substrates based on carbonized rice husk (CAC) and coconut fiber (FC) in the production of Ficus enormis Mart. ex Miq. seedlings through cutting stem from plants of clonal garden. We evaluated six substrates: commercial (control), composed of composted carbonized rice husks (CAC), coconut fiber (FC) and vermiculite (S1); 100% FC (S2); 100% CAC (S3); 50% FC and 50% CAC (S4...

Tillers induction in Bactris gasipaes var. gasipaes seedlings

Bactris gasipaes produces heart-of-palm. Peach palm is a perennial crop that has a tillering capacity, being an alternative to illegal extraction. There is a lack of studies about vegetative propagation technics for this species. The present study aimed to analyze different tillering induction methods in Bactris gasipaes var. gasipaes seedlings in four different seasons. The treatments were: 1) stem bending; 2)...

Germinação e morfologia de diásporos e plântulas de Bidens segetum Mart. ex Colla.

A prospecção de novas plantas ornamentais a partir de espécies nativas como Bidens segetum apresenta grande potencial para o mercado da floricultura, entretanto dependem de estudos que viabilizem sua propagação com fins comerciais. Assim, objetivou-se determinar condições para germinação, descrever e ilustrar a morfologia de diásporos e plântulas de B. segetum. Os testes da germinação foram realizados com diásp...

Sprouts production and rooting of Piptocarpha angustifolia minicuttings

Piptocarpha angustifolia Dusén ex. Malme (Asteraceae) is a brazilian native and pioneer tree species, occuring in Araucária Forest, with potential to ecosystem restorarion and introduction in forest, agriculture and pasture systems. Its propagation by seed presents irregular production and low number of feasible seeds while vegetative propagation by cutting of mature plants with semihardwood shoots didn’t prese...

Technology for Adequate Handling of Albizia hassleri Seeds

Albizia is an indigenous specie of estacional forest, with potential to ornamental , environmental and agroforestry systems uses. The trees of (Albizia hassleri (CHODAT) BURKAT) in adult stage can attain 35 meters of height and diameter of height of breast (DHB) of 80 centimeters. Another important characteristic of that specie is ability to fix atmospheric nitrogen. This work was conduced at Embrapa Florestas,...

Interactions Between Indolebutyric Acid, Uniconazol and Two Types of Growing Me...

Pau-de-leite (Sapium glandulatum (Vell.) Pax., Euphorbiaceae) is a native tree of several Brazilian biomes, with great interest for rehabilitation of  degraded ecosystems due to its rusticity and intense seed dispersal by birds. However, its sexual  propagation is difficult because the majority of the  flowers are male and the percentage of germination of  the seeds is very low. Considering the propagation diff...

Cutting of the Berberis laurina Billb. Using Different Concentrations of Indole...

Berberis laurina Billb. (Berberidaceae) is a native shrub from Floresta Ombrófila Mista ecological formation, very ornamental and useful specie for recovery of degraded areas. With medical applications, its fruit is edible and its roots are used as dye. This paper aims to analyze lhe induction of lhe rooting of Berberis laurina stem cuttings employing indolebutyric acid (IBA) in O, 1000 and 2000 mgL-1 concentra...
