Terminalia australis Cambess. é nativa do Brasil com ocorrência em margens de rios e importante para restauração ribeirinha. Possui frutos indeiscentes lenhosos (diásporos) sendo raros os estudos sobre sua germinação. Este estudo objetivou avaliar a eficiência tratamentos auxiliar na germinação T. australis. Foram avaliados efeitos 12 germinação: controle (T1); imersão água por diferentes períodos (T2, T3, T4); cortes nas laterais diásporo sem (T5) (T6, T7, T8); escarificação mecânica (T9)...
Rice is the staple food for over half of world's population. Infestation Schizotetranychus oryzae (Acari: Tetranychidae) causes great losses in rice productivity. To search genotypes that could better tolerate S. infestation, we evaluated morphological and production parameters Brazilian cultivars, identified two cultivars with contrasting responses. Leaf damage during infestation was similar all cultivars. However, Puitá INTA-CL resulted reduction number seeds per plant, percentage full...
Abstract Rice ( Oryza sativa L.) ssp. indica is the most cultivated species in South of Brazil. However, these plants face low temperature stress from September to November, which period early sowing, affecting plant development during initial stages growth, and reducing rice productivity. This study aimed characterize root response vegetative stage two genotypes contrasting their cold tolerance (CT, cold-tolerant; CS, cold-sensitive). Root dry weight length, as well number hairs, were...
To obtain quality seedlings of yerba mate and productive plants with a high standard raw-material, it is necessary the adequate nutrition for in nurseries. Fertilization management one key factors that contribute to better seedlings, survival, growth after planting field. Therefore, this work hypothesizes controlled nutrient-release fertilizer can be used as base fertilizers production seedlings. Thus, objective was evaluate Ilex paraguariensis subjected doses controlled-release fertilizer,...
It is largely known that low temperature stress can affect rice (Oryza sativa L.) development and yield. However, most studies have focussed on unique uninterrupted cold treatment, which not representative of conditions for early sowing in temperate subtropical areas where nights are followed by warm days during vegetative stages. In order to elucidate whether plants could recover from the damages caused repetitive nights, we submitted a cold-tolerant (CT) cold-sensitive (CS) indica genotype...
Abstract Infestation of Schizotetranychus oryzae (Acari: Tetranychidae) causes great losses in rice productivity. Puitá INTA-CL cultivar reduced the number seeds/plant, percentage full seeds, 1,000 seeds weight, and seed length, whereas infestation IRGA423 increased weight length. Reduction weight/plant caused by was higher than IRGA423. Thus, established as susceptible, tolerant to S. infestation. Photosynthetic parameters were less affected INTA-CL. also accumulation H 2 O , decreased cell...
