| ABSTRACT Seed companies increasingly need to obtain rapid and reliable results on seed quality. In this context, this study aimed at verifying the efficiency of CO2 measurement for classifying West Indian gherkin (Cucumis anguria L.) seed vigor, using three seed lots of cv. “Do Norte” and three of cv. “Nordestino”. In order to assess seed physiological quality, the following tests were performed: germination, seedling emergence, emergence speed index, shoot length, total dry matter, electrical conductivity and respiratory activity. The experimental design was completely randomized, with four replicates, and the means were compared by Tukey test at 5% probability level. Pearson’s simple correlation was performed between the traditional vigor tests and the... |

| ABSTRACT Information on the effects of climate conditions on the survival of species grown in semi-arid regions is essential and at the same time scarce, especially regarding rustic species such as West Indian gherkin (Cucumis anguria L.). Thus, this study aimed to evaluate germination, growth and biochemical alterations in C. anguria seeds under water stress and different temperature regimes. The experimental design was completely randomized, in 5 x 5 factorial scheme, composed of five osmotic potentials (0.0; -0.1; -0.2; -0.3 and -0.4 MPa) and four temperatures (20; 25; 30 °C and alternating temperatures of 20-30 ºC), with each treatment composed of four replicates of 50 seeds. The seeds were sown on paper towel (Germitest®) and germinated in Biochemical... |
