Maize grown is affected by water stress reducing photosynthetic rate and availability of in its tissues, decreasing plant yield.Monitoring potential an important indicator the degree stress.With new magnetic probe for determining leaf turgidity, it possible to evaluate status and, some cases, indicate optimal relative tolerance stress.The union old approaches gives us a better knowledge relations plats.Therefore, aim this study was understand behavior maize plants subjected stress, using...

Blossom-end rot (BER) is a physiological disorder that can affect 100% of the fruit crop depending on genotype. Tomato varieties with elongated usually have greater susceptibility to BER than other varieties. To evaluate and identify possible morphological characteristics related onset development, four long-shape tomato different BER: ‘San Marzano,’ ‘Banana Legs,’ ‘Roma,’ ‘Mini-Roma’ were examined. Our results show Marzano’ Legs’ (elongated fruit) had higher incidence lower Ca 2+...

Calcium (Ca 2+) is an essential macronutrient in plants, and low concentrations of this nutrient may result development a physiological disorder known as blossom-end rot (BER) tomato.Hormones can regulate the accumulation Ca 2+ and, consequently, fruit susceptibilities to BER.The objective study was evaluate effect gibberellin (GA), abscisic acid (ABA), 24-epibrassinolide (EBL) on BER incidence tomato.The 'Tyna c.v' tomato plants were sprayed biweekly, during anthesis, with water (control),...

Calcium (Ca2+) is a nutrient in tomato plants, of which deficiency usually causes several problems including physiological disorder known as blossom-end rot (BER) the fruit. The objective this study was to evaluate and identify morphological characteristics related susceptibility varieties BER. studied were ‘Amalia’, ‘IPA-6’, ‘M-82’, ‘Mara’, ‘Nagcarlan’, presenting different fruit formats. Physiological parameters that negatively correlated with BER plant water potential, leaf area, dry...

The objective of this study was to investigate the effects application indole-3-butyric acid (IBA) at concentrations 0, 30, 60, and 90 mg·L −1 , for 24 hours, on rooting softwood semihardwood cuttings tea ( Camellia sinensis var. ‘Yabukita’ C. assamica ‘IAC-259’) collected in winter summer. In summer, IBA increased root percentage from compared with control. However, unaffected by growth regulator. winter, regardless type cuttings. addition, ‘IAC-259’, there an increase dry weight, number...

Water stress leads to large productivity losses in rice cultivation, and plant hormones play a key role the strategies prevent harmful effects of water crop development.The objective this work was investigate brassinosteroids (BRs) development yield under irrigation deficit conditions applied during preanthesis period.Exogenous applications bioregulators were performed through leaf spray.Two dosages 24-epibrassinolide (EBL) (0.01 μM 0.1 μM), addition two ABA (2.27 mM 4.54 mM) order compare...

Abstract Chromosome number is the most fundamental trait of a karyotype. Accurate chromosome counting essential for further analyses including cytogenomics, taxonomic, evolutionary, and genomic studies. Despite its importance, miscounting common, especially in early publications on species with small morphologically similar chromosomes. Vellozia Vand. genus mainly distributed throughout South America belonging to angiosperm family Velloziaceae, dominant taxon Brazilian “campos rupestres”....

The use of herbicides is the main method weed control in soybeans. Desiccants are also being used routinely to anticipate harvest and / or minimize deterioration seed quality. There possibility direct indirect contact with such pesticides, affect community nematodes soil. However, effects their magnitudes yet be clarified, especially case selective herbicides. Thus, objective this study was evaluate soybean on harmful crop. experiment conducted transgenic ('M-SOY 7908RR'). experimental...
