“…Studies on crambe extracts have demonstrated its efficiency in controlling nematodes (Coltro-Roncato et al, 2016), whereas other studies incorporated crambe residues in soils colonized with nematodes (Nascimento, Jaime, G. E. Silva, A. R. Silva, & Alves, 2016).…”

The objective of this work is to evaluate the insecticidal and attractiveness of concentrations of hydroalcoholic extract of crambe grains on Sitophilus zeamais, and its effect on the physiological quality of corn seeds. The experiments were conducted at the Laboratory of Entomology and Seeds of the Assis Gurgacz University Center, in Cascavel, PR. The evaluation of attractiveness and insecticidal effect were evaluated using DIC, with 4 treatments (0, 5, 15 and 25% extract concentration) and 10 or 5 replications, respectively, totaling 40 experimental plots for the insect attractiveness test and 20 Experimental plots for the test of the insecticidal effect. For the experiment on the physiological quality of corn seeds submitted to the extracts, a DIC was set up in a 4 × 4 factorial scheme, factor 1 being the storage time of the seeds (0, 30, 60 and 90 days) and factor 2, the concentrations (0, 5, 15 and 25%), with 4 replicates, totaling 64 plots. Data were submitted to ANAVA, and means adjusted to regression or submitted to the Tukey test at 5% of probability, using the statistical program ASSISTAT®. The results evidenced the treatment with a hydroalcoholic extract in the concentration of 25% as the one with the highest insecticidal effect, and extract at 15% concentration yields a higher percentage of germination, normal seedlings, and mass of seedlings than the control. At 25% concentration, the extract do not negatively influence any of the parameters analyzed. Storage time above 60 days stimulates germination, mass and length of maize seedlings.

Tolerance of crambe (Crambe abyssinica Hochst) to salinity and water stress during seed germination and initial seedling growth

et al. 2019

Crambe is an oilseed plant whose oil is suitable for various industrial purposes, such as production of biodiesel, plastics, rubbers, and cosmetics. There are reports of the rusticity of this species and its potential for growth in arid and semi-arid environments, where water scarcity and soil salinity are common. However, studies regarding the tolerance of its seeds to these stresses and the physiological responses triggered during germination and seedling establishment under these conditions are incipient. The objective of this study was to evaluate the tolerance of crambe seeds to water deficit and salt stress during germination and early seedling development, as well as to investigate the role of antioxidant enzymes on tolerance to these conditions. The seeds were exposed to water and salt stresses and their performance was analyzed. Seed water content, imbibition rate, percentage and speed of germination, and the base water potential for seed germination were evaluated. In the seedlings, the following measurements were made: root and shoot length, fresh and dry matter of roots and shoots, moisture content, and activity of the enzymes superoxide dismutase (SOD), catalase (CAT), and peroxidase (POX). Water deficit and salt stress reduce the water uptake rate of the seeds, the germination and growth of seedlings. The crambe seeds had higher tolerance to salt stress than to water deficit. Absorption of salt and the action of the SOD and CAT antioxidant enzymes are part of the tolerance mechanisms of crambe seeds to salt stress.
