Effect of Copper, Zinc, Cadmium and Chromium in the Growth of Crambe

Abstract

Crambe is a promising crop for biodiesel production. However, there is no much information available about techniques and research regarding the best performance in different regions to explore its potential. The objective of this study was to evaluate the effect of cadmium, chromium, copper and zinc in the development of crambe. The study was carried out in a greenhouse and it consisted of four independent experiments in completely randomized design, with three replications. Four metals with five levels were applied: 0, 10, 15, 20 and 25 mg•kg −1 for copper, cadmium, chromium; and 0, 20, 30, 40 and 50 mg•kg −1 for zinc, in order to evaluate the growth of crambe. Data were subjected to analysis of variance and comparison of means by Tukey test at 1 and 5% significance. Despite doses of cadmium, chromium, copper and zinc in growing crambe have influenced in some of the evaluated variables of the plants, in general, their development was similar in relation to doses and the metals applied. The importance of cultivating crambe is related to grain production, based on this, copper and cadmium decreased this production.

Crop Wild Relatives (CWR) Priority in Italy: Distribution, Ecology, In Situ and Ex Situ Conservation and Expected Actions

“…Many species of the genus Crambe L. are considered industrial crops [100]. For instance, C. tataria can be used for paper production when mixed with long fibrous materials [101], to obtain higher oil and erucic acid yield [102]; C. hispanica was used for the production of special lubricants, in industrial vulcanization processes, and in those that lead to erucamide from erucic acid [103][104][105], biodiesel, meal and husk for animal feed [106].…”

Anatomy of the vegetative organs of rare and endangered species Crambe tatarica Sebeok. (Brassicaceae) growing in the conditions of the Aktobe region

“…The anatomical structure of a petiole of C. tatarica is characterized by the following features. The petioles of plants collected in populations 1 and 2 had an identical structure; they were of a radial type with well-developed numerous (15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27) bundles. In cross section, a petiole had a grooved, rounded shape.…”

“…Such characteristics make it a valuable plant material in the production of animal feed, biodiesel, and for some industrial and pharmaceutical applications. As a consequence, this species has been well studied [11][12][13][14][15][16].…”

Variation of Some Plant Growth Parameters in Coriander (Coriandrum sativum L.) with Copper Application

“…Kalidasu et al (2008), reported an increased number of primary and secondary branches with Cu application in coriander, while Huang et al (2011) examined the phenology and reproduction of Rumex dentatus in Cu-contaminated and non-Cucontaminated areas, and reported that the number of branches increased in 500 ppm Cu application compared to the control. While it has been reported that foliar-applied Cu concentrations increased the number of branches in broad bean (Vicia faba L.) (Alhasany et al, 2019), it was stated that higher Cu doses decreased the number of branches in Crambe (Crambe abyssinica H.) (Tito et al, 2014). In another previous study, it was reported that up to a certain Cu concentration (200 ppm), the number of branches increased in beans, and at higher doses, the number of branches decreased as a result of the decrease in cytokinin levels in seedlings (Bildirici, 2020).…”
