1. Sowing date influence on the soybean tolerance to defoliation at the beginning of pod formation
ABSTRACT Late sowings anticipate flowering and decrease the soybean vegetative plasticity. These changes may limit the ability of plants to tolerate leaf area losses. The objective of this research was to evaluate the sowing date effect on soybean tolerance to defoliation at the beginning of pod formation. The experiment was set in Lages (Santa Catarina Stat

2. Agronomic performance of Arabica coffee cultivars in the subtropical humid environment of Vale do Ribeira Paulista, Brazil
ABSTRACT This research is related to the evaluation of vegetative growth parameters, initial yield and incidence of pests and diseases of twelve Arabica coffee cultivars submitted to the subtropical humidity environment of Vale do Ribeira Paulista, Brazil. The experiment was performed in the Experimental Campus of the UNESP in Registro, in a randomized block

3. Wood ash as a vegetative-growth promoter in soils with subsurface compaction
RESUMO A compactação subsuperficial do solo e o estresse nutricional estão entre os principais fatores que limitam a produtividade dos cultivos agrícolas. A utilização de resíduos de origem florestal, como a cinza de madeira, é uma opção viável na recuperação química de solos, podendo proporcionar desenvolvimento radicular vigoroso em solos com

4. Spontaneous vegetative propagules differentiation in Bowdichia virgilioides seedlings maintained at MS basal medium
ABSTRACT Bowdichia virgilioides Kunth is a medium size tree used in folk medicine and in furniture manufacturing which makes it a target of extractive processes. The aim of this work was to evaluate the endogenous content of polyamines, amino acids, and sugars in seedlings of Bowdichia virgilioides that presented or not the development of spontaneously diffe

5. MINI-CUTTINGS TECHNIQUE FOR VEGETATIVE PROPAGATION OF Dalbergia nigra
ABSTRACT The usual propagation method for Dalbergia nigra is via seedings; however, the seasonal supply has a variable quantity of seeds which limits the continuous production of seedlings. Therefore, the objective of this study was to establish a vegetative propagation protocol via mini-cuttings technique for D. nigra from juvenile shoots obtained from seed

6. GROWTH AND PHYSIOLOGICAL RESPONSES OF YERBA MATE SEEDLINGS AND MINI-CUTTINGS UNDER DROUGHT STRESS
ABSTRACT Yerba mate is a tree species whose natural distribution occurs in the countries of Argentina, Paraguay, and Brazil, where most of the plantations are concentrated. For the establishment of plantations seedlings are commonly used. But alternatively, there are ex vitro vegetative propagation techniques like mini-cuttings technology, which has the pote

7. Early induction of orthotropic shoots in Coffea canephora
ABSTRACT In Coffea canephora, the number of orthotropic shoots is directly related to plant yield. The objective of this study was to evaluate the vegetative and yield performance of Coffea canephora, from the botanical variety Conilon, under different management systems for early emission of orthotropic shoots. The experiment was carried out in Ouro Preto d

8. Growth analysis of potato genotypes
ABSTRACT Analyzes of plant growth throughout the crop vegetative cycle are important to know the dynamics of the plant development. Thus the objective of this work was to study the development of potato genotypes throughout the crop cycle, in three environments. Experiments were conducted in Canoinhas-SC, Pelotas-RS, and Brasília-DF, Brazil, in the 2018 cro

9. CONTROLLED RELEASE FERTILIZER IN THE ROOTING AND PERFORMANCE OF CLONES OF Paratecoma peroba
ABSTRACT Paratecoma peroba is a native forest species of great economic and ecological interest, currently at risk of extinction. In addition to the difficulty of finding adult individuals of this species, plant production is limited, so the use of mini-cuttings can facilitate the spread of P. peroba. Thus, the objective of this study was to analyse the effe

10. Effects of Soil and Vineyard Characteristics on Volatile, Phenolic Composition and Sensory Profile of Cabernet Sauvignon Wines of Campanha Gaúcha
The influence of vineyard on wines was evaluated for the first time using a broader analytical approach: sensory analyses and several analytical techniques (gas chromatography-mass spectrometry (GC-MS), GC flame ionization detection (FID), GC-olfactometry-Osme technique (GC-O-Osme), GC × GC-MS), taking into account odoriferous compounds of Cabernet Sauvigno

11. Scientific novel: Araucaria angustifolia branch may be converted into orthotropic trunk by grafting
ABSTRACT Grafting technique has been presented as an alternative for Araucaria angustifolia propagation. However, vegetative rescuing mature trees and obtaining large numbers of propagules is difficult, because the use of branch grafts has not been indicated due to its plagiotropic and morphogenic characteristic, generally resulting in undesired growth of th

12. Growth dynamics of the branching system in grasses: an architecture-based methodology for quantitative evaluation applied to two genotypes of Paspalum vaginatum
Resumo Foi estudada a dinâmica do crescimento dos caules aéreos de Paspalum vaginatum, uma gramínea de ampla distribuição. Com o objetivo de identificar características diferenciais quantitativas entre dois genótipos, as plantas foram cultivadas ao ar livre em vasos durante dois verões consecutivos. Os eixos de diferentes ramificações foram marcado
