“…There are many reports in the literature regarding the positive effect of osmopriming in the performance of vegetable seeds, suggesting gains in the medium term of germination and the emergence of seedlings, as observed with melon and pepper (CASTAÑARES; BOUZO, 2018;SAMARAH et al, 2016). It also promotes increases in the size and phytomass of seedlings, as presented by Mavi et al (2006) for tomato, and by Batista et al (2015) for pepper, and improvements in germination and the percentage of vigorous plants, as observed with rocket (ALVES et al, 2012). Moreover, osmopriming promotes gains in the percentage and speed of germination and the emergence of seedlings, as observed for carrot (PEREIRA et al, 2008), among other examples.…”

Seeds present a fundamental role since the beginnings of agriculture, propelling the agricultural development of different people in different ages of human history. Its importance has been linked to the possibility of domesticating the most diverse plants in the past and, nowadays, of providing many biotechnological advancements represented by the most diverse cultivars and hybrids introduced into the market. However, the expression of all its capacities depends on the quality of this supply represented by the sum of physical, genetic, sanitary, and physiological attributes. This review shows how the physiological component of the quality of seeds has influenced the agricultural process for the most diverse crops, notedly, for major crops, forages, or vegetables. It is highlighted its central role in fulfilling the growing demands of a growing world population. We emphasize the preoccupation of research, development, and innovation actions in the sense of recognizing the factors that influence the physiological quality of seeds, developing and enhancing methods to estimate, preserve, and increase it, and how the adoption of high physiological quality seeds has influenced the development of the major crops.

“…One of the limiting factors for the success of the vegetables species has been the difficulty to obtain seeds capable of provides the establishment of culture with the ideal population and with uniform and vigorous seedlings (Alves et al, 2012). To occur a better expression of the set of attributes that ascertain the seed potential…”

Bioactivator on physiological performance of tomato and onion seeds

Vegetable seeds have high commercial value, in the field after sowed seeds were exposed to unfavorable environmental conditions capable of causing reductions in the yield. Thiamethoxam is a bio-activator that may confer tolerance to stresses. In this regard, we aimed to evaluate the influence of thiamethoxam in the physiological performance of four lots of tomato and onion seeds. Seeds were treated with five doses of thiamethoxam, 0.0; 0.2; 0.4; 0.6 and 0.8 ml of product per 1000 seeds. The effects of the seed treatments were evaluated by the assessments of the first count of germination, sprouting test, cold test, accelerated aging and seedling`s emergence in the greenhouse. The experimental design was completely randomized, with four replicates per lot and by species. Data were submitted to analysis of variance and adjusted by orthogonal polynomials, using the adjusting equation based on the significance of F test at 5% probability. The bioactivator provided an increase in germination percentage, the first count of ermination, germination after accelerated aging, cold test and seedling’s emergence for low vigor seed lots. The bioactivator thiamethoxam stimulates the physiological performance of tomato and onion seeds. Doses of 0.5 to 0.6 mL of thiamethoxam per 1000 seeds of tomato and onion correspond to technical maximum efficiency.
