“…by 15Á40% in field conditions (Larkin & Griffin, 2007). A similar effect of crop rotation was observed when both oilseed rape and turnip rape as preceding crops decreased the growth of Phytophthora cactorum Crown by 20% in field conditions (Mattner et al, 2008). These observations show clearly that winter turnip rape would be an excellent choice in crop rotation, especially when fewer agrochemicals should be used, even though the protective mechanisms have not yet been elucidated.…”

Winter turnip rape (Brassica rapa spp. oleifera) is an underutilized crop that deserves to be revitalized for use in high-latitude agriculture. Many crop rotations around the world are dependent on the small-grain cereals, and turnip rape as a break crop, with its range of secondary chemicals, helps to suppress weeds, nematodes and pathogenic fungi. It may be used as an energy crop, it can restrict erosion and nutrient leaching while also improving soil structure and fertility, and it requires relatively low inputs. Although winter turnip rape was once the major oil crop in Finland, in the 1970s it was replaced by spring turnip rape, the lower erucic acid and glucosinolate contents of which made it suitable for food and feed uses. Winter hardiness of the crop could be improved, and industrial end uses, such as lubricants for which high erucic acid content is preferred, targeted in the first instance. Breeding progress would be accelerated by a change from the predominantly selfincompatible breeding system to self-compatibility, now available in modern germplasm, and this would allow use of other rapid breeding methods, such as doubled haploidy. Thus, the many advantages of the winter turnip rape crop would repay its return to agriculture. In this review we will introduce the many utilization possibilities of the crop as well as give background on why more attention and research efforts should be paid towards this crop. We will also indicate some of the array of factors that have a marked role in an attempt to ecologically intensify crop production.

“…Turnip rape mulch also releases nitric oxide (Cohen & Mazzola, 2006). Crop rotations including either oilseed rape or turnip rape decreased the number of emerging weeds by 40% and it was concluded that nitriles, which are also breakdown products of glucosinolates, might have played the crucial role (Mattner et al, 2008).…”

“…Brassica species produce glucosinolates (GSLs), which upon hydrolysis by enzymes produced by soil microbes (e.g. myrosinase) produce toxic isothiocyanates (ITC) and nitriles (Halbrendt 1996;Mattner et al 2008;Motisi et al 2009). The active toxins are generally only produced when plant tissue is damaged and decomposition processes occur (Mattner et al 2008).…”

“…Biofumigation ultimately represents a form of allelopathic defence mechanism with the ability to suppress fungal pathogens, parasitic nematodes and weeds (Abawi and Widmer 2000;Mattner et al 2008). Brassica species produce glucosinolates (GSLs), which upon hydrolysis by enzymes produced by soil microbes (e.g.…”

Yeheb is a shrub endemic to the Horn of Africa. It is adapted to hot and xeric environments and known to be resistant to insect herbivores. We analysed volatile organic compounds (VOCs) from the headspace of vegetative branches (VBs) and fl owering branches (FBs), stored terpenoids from leaf and bark extracts and foliar total phenolics. Isoprene was the dominant compound in the headspace. In total, 66 VOCs were identifi ed, but only a few stored terpenes were detected. Isoprene and monoterpene emissions from FBs were at levels of 24.0 and 5.12 μg/g dw (dry weight)/h, respectively. A total of 30 compounds were emitted at signifi cantly higher rates from FBs than from VBs. The emission of large quantities of a diverse range of VOCs and the presence of high levels of total phenolics in this plant may be attributed to its defence strategy against both abiotic and biotic stresses in arid environments.
