“…This increased production in roots can be due either to the increased beet cycle length (226 vs 201 days), and to a more favourable weather, with particular regard to the rain (467 vs 157 mm). The highest yield recorded under fresh water was similar to the production levels reported in literature (Pidgeon et al, 2001;Hoffmann, et al, 2009;Shrestha et al, 2010) in different European sites. However literature does not report results regarding the effect of wastewaters on the sugar beet root yield.…”

The use of treated wastewater to irrigate the sugar beet (Beta Vulgaris L. var. saccharifera) for bioethanol could play a strategic role to contrast the use of natural water resources and increase the productivity of the crop. The 2-year experiment (2013-2014) was performed on sugar beet irrigated with fresh water and wastewater at different steps of the reclamation process (secondary and tertiary treatments). The data obtained showed that the root sugar beet yield and ethanol production under fresh water treatment (52.2 Mg ha -1 and 5446 L ha -1 ) were lower respect to that obtained from the secondary and tertiary wastewater treatments (66.7 Mg ha -1 and 6785 L ha -1 , and 58.7 Mg ha -1 and 6164 L ha -1 , respectively), with the same irrigation volumes. These results can depend on the higher quantity of nutrient uptake when wastewater is used for irrigation. In particular, the average N applied (as nitrate and ammonium) with irrigation during the growing seasons (2013 and 2014) was corresponding to the supply of 4, 28 and 20 kg ha -1 , for the fresh water, secondary, and tertiary wastewater treatments, respectively.

“…However, by resisting the temptation to conduct trials only under optimum conditions, and with judicious site selection in combination with advanced statistical tools, breeders can obtain additional useful information on genotype performance using data from multilocation trials that span the range of environments likely to be encountered in practice (Pidgeon et al 2006). In another study examining nine varieties under more mild conditions, genotype x environment interactions, though significant, were small (Hoffmann et al 2009). …”

Abiotic Stress in Sugar Beet

The production of sugar beet (Beta vulgaris L.) is often limited by environmental conditions that cause decreased rates of photosynthesis, canopy expansion, root growth and sucrose accumulation. These conditions include insufficient water, heat, freezing temperatures and salinity. Compared to other crops such as cereals, harvestable sugar yields can be obtained even under harsh growing conditions. However, the realization of maximum production efficiency and profits demands that varieties must show less susceptibility to abiotic stress and improved yield stability across a range of environments. This is particularly urgent in light of climate change models that predict hotter and drier growing conditions for many areas. There are only limited breeding efforts to improve the tolerance of new varieties to these stresses, in part because the mechanisms of tolerance are poorly understood and methods to screen germplasm for resistant genotypes have not been fully developed. Fortunately, there appears to be significant genotypic diversity for tolerance to drought, heat, cold and salinity within sugar beet germplasm, so opportunities exist for varietal improvements. Developments in irrigation technologies and innovations in agronomy and soil management techniques may also contribute to improved yields of crops faced with abiotic stresses.

“…If a genotype has the same direction as a certain environment in the bivariate plot, it is considered to be specially suited for that environment. 20) To explore the effect of geographic-climate factors on bioactive components traits, five bioactive components and nine geographic-climate factors in two years were analyzed by stepwise regression analysis (SRA) with SPSS 16.0. Geographic-climate factors were independent variables (i.e., X 1 , sunshine duration; X 2 , mean annual temperature; X 3 , mean temperature in July; X 4 , min.…”

Methods to improve the bioactive component content of cultivated licorice have become the bottleneck of industrial licorice extraction for pharmaceutical use. To evaluate the effects of genotype, environment and their interaction on major bioactive components, we analyzed the five bioactive components: liquiritin (LQ), liquiritigenin (LQG), glycyrrhizin (GL), isoliquiritin (ILQ) and isoliquiritigenin (ILQG) of four diverse licorice varieties grown in four distinct environments in northern China during 2010-11. Analysis of variance showed that environmental and genotypic effects were significant (p<0.01) for all five bioactive components. Additionally, their interaction was significant (p<0.05) for GL in the 2-year study period. LQ and ILQ were mainly affected by genetic factors and have great potential for genetic improvement, whereas LQG and ILQG were mainly affected by environmental factors. GL was similarly affected by environmental and genetic factors. Biplot of the principal component analysis showed that for quality breeding, G2 (WNT-1) and G3 (JX-1) are two relatively preferable genotypes, and E2 (Chifeng) location is suitable for accumulation of the bioactive components of these two genotypes. Stepwise regression analysis showed that sunshine and rainfall are the dominant environmental factors for licorice bioactive component accumulation; increased duration of sunshine is advantageous to GL accumulation whereas declining rainfall is conducive to LQG and ILQG accumulation. These results provide a theoretical basis for initiating licorice breeding programs with increased bioactive components and improved quality.Key words licorice (Glycyrrhiza uralensis); genotype; environment; bioactive component; geographical location; quality breeding Licorice (Glycyrrhiza uralensis FISCH.) belongs to the family Leguminosae, and has been used as a popular herbal medicine for thousands of years in China.1,2) Biological activities of licorice have been attributed to triterpene saponins, various types of flavonoids, such as glycyrrhizin (GL), liquiritin (LQ), liquiritigenin (LQG), isoliquiritin (ILQ) and isoliquiritigenin (ILQG), and other bioactive components, which exhibit anti-inflammatory, anti-viral, anti-allergenic, anti-ulcer and anti-oxidative properties, and are also believed to have chemopreventive activity against cancer and AIDS. [3][4][5] Licorice is one of the most important industrial materials for pharmaceuticals, 6) and the total amount of import and export in China reached 13960 t in 2011.7) More than 90% of total licorice production in 2005 was Glycyrrhiza uralensis. 5)Due to the low content of bioactive components in cultivated populations, licorice is mainly extracted from wild variety despite its limited yield, which has restricted the extent of industrial extraction. With increasing demands for licorice worldwide, wild licorice is unable to meet the global needs. 8)Hence, methods to improve the quality of cultivated licorice have become the bottleneck of industrial licorice extraction. Furthermore, ...
