The survey entitled “Germination and vigor of seeds of Dimorphandra gardneriana subjected to water stress in different temperatures”, published in science, volume 46, number 12 of 2016, aimed to assess the germination and vigor of seeds of Dimophandra gardneriana when subjected to different osmotic potentials and temperatures. This species has green beans rich in rutin, a widespread flavonoid with antioxidant properties, anti-inflammatory and circulatory, attaches great importance. D. gardneriana is a species with moderate population density, being found in the States of Piau\u00ed, Minas Gerais and Cear\u00e1. Even so, there are a few basic studies to understand their ecological and physiological attributes under stress conditions. For the simulation of the test researchers conducted a simulation experiment of water restriction with polyethylene glycol 6000 solution (PEG 6000) osmotic potential of 0,-0.2; -0.4; -0.6; -0.8 and-1.0 Mpa and at temperatures of 20, 25, 30 and 35\u00bac obtained with the aid of germination plant of type BOD. From the evaluation of the effect of these treatments, the researchers determined the percentage of germination and vigor (germination speed index, length and phytomass of dry shoot and roots) of seeds, using a random design in four repetitions. They say the results show that from-0.4 MPa there was a drastic reduction of germination and vigor of seeds in all temperatures, for those subjected to a temperature of 25\u00b0 C in the concentration of PEG 600-0, 2MPa, the best results were observed for these parameters.<\/p>\n

For the researcher Marina Matias Ursulino, the results provide important information on the physiological characteristics of the species Dimorphandra gardneriana, used for production of various pharmacological products. In practice, this information can serve to guide the vivericultores grant in the production of quality seedlings of this species. The researcher also highlights that there are few studies that focuses on physiological characteristics of this plant description.<\/p>\n
