Metabolic response induced by abiotic elicitors in seedlings.

Applying elicitors in plants growing under natural conditions change the metabolic content of volatile compounds extracted from their tissues. Here, we have investigated how abiotic elicitors influence the volatile composition of the ethyl acetate extract of seedlings propagated and cultures. Abiotic factors such as salicylic acid, silver nitrate, light quality, and cultivation mode affected the composition of volatile compounds in ethyl acetate extract of leaves seedlings.

Morphoanatomical, Physiological, and Biochemical Indicators in L. Germination and Growth in Response to Fluoride.

Fluoride is one of the main phytotoxic environmental pollutants, and high concentrations (10-30 mg L) are commonly detected in surface and groundwater. Little, however, is known about the effects of this pollutant on crops that require irrigation during their development, which, in addition to phytotoxicity, may cause negative human health effects. Thus, the aim of this study was to characterize the effects of potassium fluoride (KF) on the germination of lettuce seeds and identify the physiological and anatomical markers of this pollutant's action on plants exposed to it during growth.

Associations between Integument Color and Physical and Physiological Quality in Seeds.

is a native Brazilian species typical of the cerrado biome, belonging to the Leguminosae-Papilionoideae (Fabaceae) family and popularly known as sucupira branca or faveiro. Its seeds exhibit different integument colors, which may exhibit a direct association to physiological quality related to higher germination percentage rates, vigor, and germination speed index (GSI). Therefore, selection and evaluation methods concerning seed quality are required for the preservation of this species.

Fluoride effect indicators in seeds and seedlings.

Background: Fluoride (F) is one of the main environmental pollutants, and high concentrations are commonly detected in the air and in both surface and groundwater. However, the effects of this pollutant on seed germination and on the initial growth of crop seedlings are still poorly understood. In this context, the aim of this study was to assess morphoanatomical, physiological and biochemical fluoride effect indicators in L.

Radiographic Imaging as a Quality Index Proxy for Seeds.

Efficient methodologies for automated seed quality evaluations are important for the seed industry. Advanced seed technology research requires the use of adequate methods to ensure good seed performance under adverse environmental conditions; thus, providing producers with detailed, quick, and accurate information on structural seed integrity and ensuring vigorous production. To address this problem, this study aimed to determine (Marandu cv.

Multifunctional potential of endophytic bacteria from Anacardium othonianum Rizzini in promoting in vitro and ex vitro plant growth.

Anacardium othonianum Rizzini, a cashew tree native to the Brazilian Cerrado, is economically important due to its applications in the food, chemical and pharmaceutical industries. However, A. othonianum yields a crop with low productivity due to a number of factors, such as nutritionally poor soils, drought and losses due to pests and diseases.

Bioindicator potential of to simulated rainfall containing potassium fluoride.

Background: Fluoride pollution is a global problem because of its high phytotoxicity. Fluoride is released in air, water and soil through industrial processes, where it damages various plant species. is widely distributed in Brazil, India and China and has been extensively used as a phytoremediation species in heavy metal-contaminated soils.

Tolerance of to Aluminum: Germination and Plant Growth.

Native Cerrado plants are exposed to soils with low pH and high availability of Al. In this study, we measured the Al content in adult plants, and investigated the effects of various Al doses on germination and early development of plants. For germination tests, the seeds were soaked in Al solution and evaluated for twenty days in growth chambers.
