Bromeliads have been gaining ground in the economic scenario due mainly to their use as ornamental plants. Bromeliads of the genus Dyckia exhibit different morphologies, and therefore, have relevance in this market. However, some species are threatened due to the extraction of plants from their natural environments. Many of these species are endemi...
Salinity and water deficiency are factors that limit the initial development of crops, directly interfering with the efficiency of food production. Studies on the behavior of cultivable species under stress are important to determine management actions; therefore, the mechanisms involved in post-stress recovery should be investigated. The objective...
Physalis peruviana L. is a small fruit known for the great pharmacological importance, since it has high levels of vitamin A, C, iron, and phosphorus. Cultural practices such as training and pruning can influence the architecture of the plant, in such a way to obtain fruits of better quality. Therefore, the objective of this work was to evaluate th...
Physalis peruviana L., a small fruit belonging to the Solanaceae family, is known for the high vitamins A and C, iron, and phosphorus content. As it presents numerous opportunities for adding value to family producers, it has been gaining space in the consumer market. Characteristics such as fruit size and seed extraction methods can interfere with...
Micronutrients are used in small amounts by plants and changes in metabolic processes of seeds can improve germination and vigor; however, little is known about the effects of the combination of Zn, Co, and Mo on corn seeds. Thus, the objective of this study was to evaluate the effects of the application of Zn, Co, and Mo on the physiological poten...
Snap beans (Phaseolus vulgaris L.) belong to the same species as common beans and require similar management practices. Studies aimed at nitrogen fertilization in pod beans are scarce, but necessary, considering the demand from farmers for greater productivity of these beans. The objective of this study was to evaluate the effects of nitrogen ferti...
Physalis peruviana L. is a plant that produces small sweet berries of great nutritional and medicinal importance. This plant is propagated mainly through seeds, which requires information on germination response to temperature and light changes. Thus, the present study aimed to evaluate the use of different temperatures and light wavelengths on the...
O uso de herbicidas deve ser feito de forma racional, dando prioridade em evitar possíveis efeitos adversos nas culturas subsequentes. O objetivo foi avaliar o efeito residual dos herbicidas pré-emergentes no crescimento e no desenvolvimento inicial, bem como a composição bioquímica das plântulas de feijão vagem. O delineamento experimental utiliza...
INTRODUCTION: The snap bean (Phaseolus vulgaris L.) is a legume that is widely consumed on the world scenario due to its biochemical composition and nutritional quality (Furlan et al., 2016). Besides the nutritional compounds, the snap bean presents antioxidants properties, inhibiting or retarding the oxidative damage, which avoids the propagation...
INTRODUCTION: The snap bean belong to the same botanical Family and species of common bean (Phaseolus vulgaris L.), however is classified as a vegetable because its immature pods with tenuous grains are the consumed part, thus is essential the obtaining of genotypes that ally high yields and great pod quality. An alternative, which has been used to...
INTRODUCTION: The comprehension of the plant vegetative attributes in the yield is of a fundamental importance to the management, as well as to the genetic improvement. The main tool used in this study are the estimation of correlations, however, because they do not provide the relative importance of the direct and indirect influence of other chara...
INTRODUCTION: The snap bean (Phaseolus vulgaris L.) is a vegetable consumed around the world. The physiological and morphological quality of pods are important characteristics for determinate the commercial pattern, so techniques must to be used for increase the production of pods. Inoculation and application of nutrients on the leaves are manageme...
The plants synthetize a
big quantity of chemically diverse compounds, which discharged into the
environment influence in a decisive manner in the species dynamics that form
the agroecosystems, phenomenon denominated allelopathy. The study had the aim of ...

... Among the tested substrates, soil and vermiculite showed an inferior performance regarding GSI at any of the tested temperatures. Elevated temperatures favor the increase of vigor, causes the establishment to be uniform and faster, minimizes the contact time of the seed with the soil, it can contain pathogens and pests (MORESCO et al. 2021). Figure 7. Germination rate index of seeds of P. catingicola subsp. ...
... High-vigour seeds ensure better establishment in the field, with the developed plants having a greater advantage; generally, the purpose of vigour testing is to determine the degree of physiological quality of seeds obtained under different conditions (OMURA et al., 2020). Evaluating vigour, considered fundamental and sensitive in maize seeds, is generally employed using the accelerated ageing test for this crop. ...
... Amos et al. [12] reported that increasing N doses also increase the number of grains per plant; Edje et al. [13] stated in their studies that nitrogen increases the pods per plant, grain yield and the plant height. In addition, Omura et al. [14] stated that more pods were formed with nitrogen applied by splitting. ...
... Emergence speed index was best for germinating uchuva seeds and three other Physalis species shaded by white and red nets. Pellizzaro et al. (2019) germinated uchuva seeds in incubators at a constant temperature of 25 °C and at diurnally fluctuating temperatures from 25 to 30 °C. Seeds were also exposed to blue, red, and white light conditions and total darkness. ...

... Whereas other incubations of rest of plants revealed that chick pea seeds were totally compromised irrespective used aqueous extracts. Recent results are although unusual but occasionally reported from Brazil (Gomes et al., 2017). On the contrary other scientists found concentration dependent germination inhibition as well as yield and growth inhibition mediated by different plant extracts. ...
