Hyptis suaveolens (L.) POIT., UNDER CULTIVATION CONDITION.This study was performed to establish the correlation between growth conditions and essential oil composition of from Alfenas (MG), Brazil.The plants were grown in a greenhouse, four treatments used they harvested at two different periods time (60 135-day-old plants).The determined by GC-MS analysis.The terpenes spathulenol, globulol, dehydroabietol, a-cadinol β-phellandrene major constituents found oil.Oxygenated sesquiterpenes...
Abstract This study was performed to verify the influence of photoperiod, plant age and nitrogen, phosphorus potassium availability in essential oil composition Hyptis suaveolens (L.) Poit from Alfenas (MG), Brazil. The plants were grown a greenhouse six treatments used. These harvested at two different periods (60 135 day‐old plants). determined by GC–MS analysis using DB5 bonded phase column. terpenes spathulenol (8.43–24.70%), globulol (6.89–14.55%), dehydroabietol (3.84–11.80%), α...
Abstract The seeds of Schinus molle are referred to as displaying physical dormancy because their water-impermeable endocarp. Therefore, this work aimed evaluate the germination S. related environmental conditions, scarification, storage time and seed anatomy. Various experiments were conducted test alleviation in newly collected stored seeds. Acid-scarified incubated under continuous light at 25°C showed greatest vigour germination. separation by specific gravity revealed a higher...
O objetivo do presente trabalho foi à verificação efeito alelopático de Hyptis. suaveolens na germinação sorgo, alface e rabanete, bem como, a comprovação da existência compostos com potencial alelopático. Sementes rabanete foram semeadas em substrato constituído areia, terra adubo orgânico contendo folhas H. suaveolens. As análises feitas considerando protrusão radícula para o término evento germinativo. Foi calculado IVG (índice velocidade germinação) %G (porcentagem germinação). Os...
We investigated morpho-physiological plasticity in the leaves of Ocotea odorifera trees growing under different environmental conditions a fragmented forest. Microclimatic data were collected pasture matrix, forest edge, and interior three Atlantic Forest fragments. Leaf gas exchange, as well leaf anatomy paradermal transversal sections, evaluated individuals these environments. Radiation intensity temperature had higher effects matrix compared with edge. However, internal portions canopy...
Este trabalho foi realizado com os objetivos de avaliar o crescimento das espécies e identificar seu padrão discutir sobre a eficiência do método em relação ao processo restauração vegetal. O levantamento dos dados 32 meses após plantio mudas. Para amostragem empregado área fixa parcelas, sendo utilizadas cinco áreas amostrais, que foram selecionadas modo abranger toda extensão reflorestada, contendo 200 indivíduos/área amostral. Foram realizadas, todas as plantas amostradas estrato arbóreo...
Hyptis suaveolens (L.) Poit. é uma planta da família Lamiaceae, considerada espécie tipicamente invasora. Entretanto, produtora de óleo essencial, ao qual várias atividades biológicas são atribuídas. Informações sobre o desenvolvimento reprodutivo nesta seriam úteis à elucidação mecanismos adaptativos relacionados indução floral em espécies invasoras, e incremento na produção devido sua preponderância nas flores. Assim, aqui caracterizamos alguns aspectos do suaveolens. Plantas H. foram...
O alagamento no solo é um fenômeno que reduz a sobrevivência, o crescimento e desenvolvimento de plantas, podendo ocasionar queda na produtividade quando essas são agricultáveis. maracujazeiro (Passiflora edulis Sims) uma frutífera comercial com propriedades medicinais cuja produção incentiva irrigação; não encontrados estudos apresentem efeitos do excesso água sobre estas plantas. objetivo deste trabalho foi verificar alterações morfoanatômicas fisiológicas inicial plântulas expostas...
Soil water saturation requires different adaptative strategies by tree species that live under such conditions. We aimed to study the responses ensure flooding tolerance and so provide support for recovery projects with degraded areas subject flooding. evaluated ecophysiology of Cedrela fissilis saturations, including anatomical traits, gas exchange parameters, antioxidant system analysis growth. subjected 100 day-old plants three treatments: Control (FC) where substrate was kept at field...
O Código Florestal Brasileiro de 2012 admite a inclusão da reserva legal às áreas preservação permanente e define uso consolidado. Assim, esta pesquisa avaliou evolução espaço-temporal do ocupação solo nas proteção ambiental, 2008 2016, sub-bacia hidrográfica Rio São Tomé, sul Minas Gerais, diante novo marco florestal legal. A partir imagens satélite Landsat 2008, 2013 foram mapeados os usos as ocupações permanente. tais mapas identificados ilegais Em 55,66% das continham ilegal; entretanto,...
Survival and dynamics of forests depend largely on the seed rain.Thus, studies densities rain can provide important information for conservation management forest fragments.The aim this study was to evaluate in a fragment semideciduous Atlantic southern Minas Gerais, Brazil, order to: identify species frequency seeds that were dispersed; relations between occurrence edge effect fragment, at different times.We used nested model analysis variance.We verified differences among times interior...
The distance effect of the edge and two matrices (pasture sugar cane) on microclimate anatomical physiological properties Psychotria vellosiana leaves were studied in semideciduous forest fragments southern Minas Gerais.The plots set at distances (0, 20, 40, 60 80 m) from to interior each fragment: 0, 20 40 m considered edge, whereas interior.Microclimate data collected all radiation canopy openness m.Leaves for analysis their chlorophyll content properties.No differences found between...
The present article aims to relate the activities developed and results obtained, in research extension projects on Marolo (Annona crassiflora Mart.), performed by Universidade Federal de Alfenas (UNIFAL- MG) association with Empresa Assistência Técnica e Extensão Rural Minas Gerais (EMATER-MG) as well other institutions. For this purpose, there were actions taken sense of checking participation commercialization marolo generation rent labor for rural families; surveying selection...
