“…Results in Table 7 show that irrigated artichoke plants with 75 and 100% ETc magnetized water at produced the highest inulin content in edible part of heads in both seasons. Results are in harmony with those obtained by (Aduldecha et al, 2016) reported that inulin production was significantly reduced by low soil moisture content, and the decline was particularly noticeable under extreme drought stress, also, (Tartoura et al, 2020) found that irrigation with magnetized water gave the highest values of inulin compared with control non-magnetized water treatment on Jerusalem artichoke plants. Fertilizing with 100 NPK produced the highest values of inulin content in total heads with no significant differences with fertilizing with 75% of recommended dose in both seasons Table 7.…”

Two field experiments were carried out during the two growing seasons of 2019/2020 and 2020/2021 at the El Kanater Hort. Res. Station, El Kaloubia governorate Egypt, to study the effect of irrigation with normal water, magnetized water at 100, 75% of potential evapotranspiration, under different levels of N, P and K of the recommended doses fertilization and their combined interactions on productivity and water use efficiency of globe artichoke. The experiment design was a split plot with three replicates and the main plots were allocated to irrigation water treatments whereas the sub-plots were concerned with NPK fertilizer levels. The results indicate that irrigation with 75 or 100% ETc magnetic water produced the maximum vegetative growth, early and total yield / plant and ton/fed, head dry matter percent, inulin content, water use efficiency and head NPK percentages. The optimal NPK fertilizer rate for artichoke plants is 75% and irrigation with magnetized water at 75% ETc mixed with NPK fertilizers at 75% of recommended rates produced the best interaction of yield characters and its constituent. The highest water use efficiency (7.51 kg m-3 and 7.40 kg m-3 )) was obtained by 75% ETc magnetized mixed by100 or 75 % NPK as well as ETc 75% magnetized water combined with 75% of recommended NPK (9.21 kg m-3 ) in the first and second season respectively, It might be concluded that irrigated artichoke plants with 75% ETc magnetized water and fertilize with 75% of recommended NPK resulted in a 25% reduction in irrigation water and NPK fertilization.

“…Likewise, the inulin content in collections of wild dahlia (Dahlia coccinea) ranged between 23.9-42.5 g/100 g (Santana et al, 2016), however, when these plants were cultivated, their concentration increased significantly. These results suggest that the inulin concentration is associated with genetic, physiological and environmental factors (temperature and photoperiod) (Başaran et al, 2017), without considering the changes suffered by the root over time, due to the fact that as the roots get older, they accumulate reserves in the form of inulin and longer-chain fructans (Aduldecha et al, 2016).…”

The aim of this research was to evaluate the physicochemical quality, antioxidant capacity and nutritional value in tuberous roots of some wild dahlia species. The experiment was carried out in the Department of Plant Science of the Autonomous University Chapingo, Mexico. Plants were established in a randomized complete block design with five replications. The total soluble solids (TSS), titratable acidity (TA), vitamin C (VC), total phenols (TP), antioxidant capacity (AC), inulin and its proximate composition were evaluated. Among the materials analyzed, the most outstanding wild species were Dahlia campanulata, D. coccinea and D. brevis, where D. campanulata stood out for its concentration of VC (0.05 mg 100 g-1), AC (1.88 mg VCEAC g-1), inulin, DM and TC (72.25, 24.38 and 88.37%, respectively), however, the inulin content was similar to D. coccinea (66.17%), which was also outstanding with respect to the content of TP (1.74 mg GA g-1). Likewise, D. brevis presented the highest values of RFi (5.49%) and A (78.42%). According to our results, the tuberous roots of wild dahlia species can be used as food, as well as being a source of selection of traits of nutraceutic interest for genetic improvement. ********* In press - Online First.

“…Genotypes, JA5, JA125 and JA60 were tolerant to severe drought and recommended for drought conditions. Another genotype, HEL65, gave high inulin content under field capacity water levels and tolerated moderate drought, showing high inulin content under 50% and 25% of soil available water [3]. The positive qualities of this genotype should be developed by breeding.…”

Drought is more concerned to be a huge problem for agriculture as it affects plant growth and yield. Endophytic bacteria act as plant growth promoting bacteria that have roles for improving plant growth under stress conditions. The properties of four strains of endophytic bacteria were determined under water deficit medium with 20% polyethylene glycol. Bacillus aquimaris strain 3.13 showed high 1-aminocyclopropane-1-carboxylate (ACC) deaminase production; Micrococcus luteus strain 4.43 produced indole acetic acid (IAA). Exopolysaccharide production was high in Bacillus methylotrophicus strain 5.18 while Bacillus sp. strain 5.2 did not show major properties for drought response. Inoculation of endophytic bacteria into plants, strain 3.13 and 4.43 increased height, shoot and root weight, root length, root diameter, root volume, root area and root surface of Jerusalem artichoke grown under water limitation, clearly shown in water supply at 1/3 of available water. These increases were caused by bacteria ACC deaminase and IAA production; moreover, strain 4.43 boosted leaf area and chlorophyll levels, leading to increased photosynthesis under drought at 60 days of planting. The harvest index was high in the treatment with strain 4.43 and 3.13 under 1/3 of available water, promoting tuber numbers and tuber weight. Inulin content was unchanged in the control between well-watered and drought conditions. In comparison, inulin levels were higher in the endophytic bacteria treatment under both conditions, although yields dipped under drought. Thus, the endophytic bacteria promoted in plant growth and yield under drought; they had outstanding function in the enhancement of inulin content under wellwatered condition.
