1. Morphological characterization of fruits, endocarp, seed and seedlings of cajá-manga (Spondias dulcis)
ABSTRACT The Cerrado biome has several species that can generate income, and the cajá-manga is one of these native species with great potential but with scarce information about its morphological characterization. Thus, this work aimed to characterize the fruit, endocarp, seeds, and seedlings of cajá-manga morphologically. The fruits were evaluated by the

2. Irrigation management based on reference evapotranspiration for pre-sprouted plantlets of sugarcane cultivars
ABSTRACT The pre-sprouted sugarcane plantlets (PSP) system aims the production of healthy and vigorous plants in reduced time, reducing the number of stalks needed for planting. Irrigation is used in all PSP system stages and water management plays an important role. Stage 1 acclimation follows the budding stage and lasts for approximately 21 days. At this s

3. VEGETATIVE PROPAGATION OF Cordia trichotoma (VELL.) ARRAB. EX STEUD. BY CUTTINGS FROM SHOOTS AND ROOTS
ABSTRACT Cordia (Cordia trichotoma (Vell.) Arrab. ex Steud.) is a native species that has high quality wood and potential for the establishment of commercial plantations. However, its propagation by seeds is difficult, and vegetative propagation is a good alternative. The aim of this study was to evaluate the vegetative propagation of cordia by cuttings from

4. GERMINATION POTENTIAL AND VEGETATIVE PROPAGATION OF Aegiphila brachiata VELL
ABSTRACT The objective of this study was to evaluate the germination potential of Aegiphila brachiata (peloteiro) and its propagation through stem-cuttings, as well as how the age of parental plants and the application indolebutyric acid (IBA) and inoculant of Azospirillum brasilense influence adventitious rooting of the species. Thus, the physical character

5. PhenoRoots: an inexpensive non-invasive phenotyping system to assess the variability of the root system architecture
ABSTRACT: The root system architecture (RSA) of plants and its functioning play a fundamental role in a number of plant growth mechanisms including water and nutrient uptake. Optimization of the RSA is important for stable and increased plant productivity under adverse conditions. Despite its great importance, studying the RSA is notoriously laborious becaus

6. In vitro conservation of Poincianella pyramidalis (Tul.) L.P. Queiroz under minimal growth conditions
RESUMO Poincianella pyramidalis (Tul.) L.P. Queiroz, é uma espécie endêmica da Caatinga, se destaca pela importância nas atividades madeireira e medicinal. Este estudo teve como objetivo avaliar o efeito dos agentes osmóticos sacarose, sorbitol e manitol e o retardante de crescimento paclobutrazol (PBZ) na indução do crescimento mínimo in vitro de P.

7. Feasibility of the new method for orchid in vitro rooting using liquid and chemical sterilized culture medium under different sucrose concentration
Resumo A propagação in vitro de orquídeas é a única técnica comercial em larga escala para obtenção de plântulas saudáveis e de alta qualidade com origem clonal. O uso de novas tecnologias em sistemas de cultura de tecidos vegetais pode levar a aumentos de eficiência e redução de custos dos sistemas de micropropagação. O principal sistema de m

8. Regulators, culture media and types of lights in vitro lavender culture
RESUMO: Lavanda é uma planta ornamental aromática que é amplamente utilizada nas indústrias de perfumaria, farmacêutica, cosmética e alimentícia e por isso é importante estudar maneiras de promover a produção dessa matéria-prima. Para tanto, foram realizados quatro experimentos com o objetivo de estudar a germinação e o desenvolvimento inicial

9. Micropropagation of Guadua chacoensis (Rojas) Londoño & P. M. Peterson1
RESUMO A cadeia produtiva de bambu, no Brasil, ainda é incipiente, e tem baixa oferta de mudas devido aos métodos convencionais de propagação. Objetivou-se, aqui, estabelecer um protocolo de micropropagação para Guadua chacoensis. Explantes de matrizes cultivadas em ambiente controlado resultaram em menor contaminação, relativamente aos de plantas cu

10. A leaf bud technique for rapid propagation of cassava (Manihot esculenta Crantz)
ABSTRACT The slow rate of multiplication is one of the main constraints on the production of cassava (Manihot esculenta Crantz). This work aimed to evaluate the use of leaf buds for rapid propagation of cassava varieties. Leaf buds were excised from three cassava varieties (BRS Kiriris, 98150-06 and 9624-09) for plantlet generation. The experiment was comple

11. Endophytic interaction of Bacillus sp. in micropropagated banana plantlets
Abstract: The banana tree is associated with different species of endophytic bacteria that can stimulate plant growth. However, further studies are needed to better understand the relationships between this group of bacteria and the host plant. The objective of this study was to investigate the localization of the EB-40 (Bacillus sp.) through anatomical and

12. Somatic embryogenesis in the commercial papaya hybrid UENF/Caliman 01 relying on plantlet production from sexed adult hermaphrodite donor plants
Abstract: Somatic embryogenesis from explants from hermaphrodite papaya mother plants is an alternative for the production of true-to-type plants without the need for sexing. This study aimed to analyze hormonal and osmotic inducers in different somatic embryogenesis stages in the commercial hermaphrodite hybrid papaya UENF/Caliman 01. Leaf disks from in vit
