Temporary immersion bioreactors (TIB) are effective to significantly increase sugarcane <em>in vitro </em>shoot proliferation rate from 1:4 in conventional containers to about 1:35. Sugarcane micropropagation in TIBs under NaCl stress may help screen mutants with salinity tolerance. We developed the experiment shown here to identify a NaCl concentration able to stress shoot in TIBs. At 30 days of culture initiation with different NaCl levels (0 - 200 mM), explant multiplication rate, shoot cluster fresh mass, and levels of aldehydes, chlorophylls, carotenoids and phenolics were determined in the plant material. Content of soluble phenolics in the culture medium was also evaluated. Addition of NaCl decreased shoot multiplication rate and fresh mass. Other statistically significant differences were recorded but the most important were noted in the increased contents of carotenoids, malondialdehyde, other aldehydes and soluble phenolics in the plants, and in the soluble phenolics in the culture medium. This research may be useful for future experiments of <em>in vitro </em>selection of new sugarcane genetic materials with NaCl tolerance. Fifty percent of multiplication rate was reduced with 89 mM NaCl which can be used to stress shoots during micropropagation in TIBs and eventually detect mutants with salt tolerance.</p> Daviel Gómez, Lázaro Hernández, Bárbara Valle, Julia Martínez, Mariela Cid, Maritza Escalona, Martha Hernández, Lourdes Yabor, Gerrit T.S.

The effect of branch position on seed weight and oil content has not been previously reported in canola. Field experiments were conducted to explore the impact of branch position on seed weight and oil content. Four canola genotypes, Zheyou 50, Zhongshuang 11, Zheyou 18, and Zheshuang 8, were used to evaluate seed weight, oil content, carbohydrate profile, and nitrogen content in the main inflorescence and branches from the top to the bottom of the main stem. Seed weight and oil content decreased from the main inflorescence to the lower branches in the four genotypes. Lower carbohydrate and nitrogen content in the seed and low transport efficiency of the two chemical compounds in the silique and branches were responsible for the lower seed weight and oil content in Zheshuang 8 and Zheyou 18, respectively. However, the decreasing seed weight and oil content in the branches did not correspond with decreasing carbohydrate and nitrogen content in the branches from the top to the bottom. The result suggested complex carbohydrate and nitrogen metabolism in the canola seed in the different branches.</p> Yun Ren, Jianfang Zhu, Yichun Wang, Shanlin Ma, Genru Ye, Shuijin Hua ##submission.copyrightStatement## Mon, 18 Dec 2017 00:00:00 +0100 Young herbaceous legumes – a natural reserve of bioactive compounds and antioxidants for healthy food and supplements <span lang="EN-GB">Young plants of clover (<em>Trifolium pratense</em> L. and <em>T. medium</em> L.), medick (<em>Medicago sativa</em> L. and <em>M. lupulina</em> L.), sainfoin (<em>Onobrychis viciifolia</em> Scop.) and milkvetch (<em>Astragalus glycyphyllos</em> L. and <em>A. cicer</em> L.), were investigated for total contents of phenolics, flavonoids, isoflavones, condensed tannins and triterpene saponins as well as their extracts for antiradical and ferrous ion chelating activity. The impact of two sample drying methods on the aforementioned characters was compared. The phytochemical concentrations were higher in the freeze-dried legumes; however, antioxidant activities were generally higher of oven-dried samples. Both the composition of health promoting phytochemicals and antioxidant properties were strongly species-dependent. Among the species tested, <em>Trifolium </em>spp. were most abundant in isoflavones, <em>Medicago </em>spp. – in saponins and <em>O. viciifolia</em> – in tannins. Plants of <em>T. medium</em> and <em>O. viciifolia</em> were rich in TPC. The extracts of <em>T. pratense,</em> <em>O. viciifolia</em> and <em>A. cicer</em> possessed significant antiradical activity; the extracts from <em>Astragalus </em>spp. proved to be promising chelators of ferrous ion. We concluded that young perennial legumes could be considered as potential candidates for the development of nutraceuticals and functional food ingredients to accommodate the need for a particular bioactive component or property.</span> Bronislava Butkutė, Raimondas Benetis, Audrius Padarauskas, Jurgita Cesevičienė, Audronė Dagilytė, Lukas Taujenis, Hiliaras Rodovičius, Nijolė Lemežienė ##submission.copyrightStatement## Tue, 05 Dec 2017 00:00:00 +0100 Exploring the better genetic options from indigenous material to cultivate tomato under high temperature regime <p>Screening test was conducted on 54genotypes of tomato to analyze the effect of heat stress and categorize them as heat tolerant or heat susceptible ones. Seedlings were grown at temperatures of 28/22<sup>o</sup>C day/night. Four weeks after sowing, plants were exposed to high temperatures of 40/32<sup>o</sup>C day/night for one week. Data for various morphological (root and shoot length, root and shoot fresh and dry weight, number of leaves) and physiological parameters (chlorophyll contents, sub-stomatal CO<sub>2</sub>, transpiration rate, stomatal conductance, photosynthetic rate, water use efficiency and leaf temperature) were recorded. Heat stress had a negative effect on all physiological and morphological processes of the genotypes. However, “Parter Improved”, “Legend” and “Roma” were the most tolerant genotypes whereas “Grus Chovka”, “Nepoli”, “Tima France”, “Kaldera” and “Cold Set” were susceptible to heat stress.</p> Araiz Nazir, Muhammad Rashid Shaheen, Choudhary M Ayyub, Rashid Hussain, Nadeem Sarwer, Muhammad Imran, Muhammad Aurangzaib, Muhammad Nawaz, Muhammad Faizan Ali Khan, Yussra Yawad, Munawar Iqbal ##submission.copyrightStatement## Fri, 01 Dec 2017 00:00:00 +0100 Phytochemical composition, antioxidant capacity and ACE-inhibitory activity of China-grown radish seeds The seeds of nine China-grown radish cultivars were analyzed for their phytochemical composition, antioxidant properties and ACE-inhibitory activity. Radish seeds contained 36.87–43.06% (w/w) oils, whereas 64.55–69.26% of the fatty acids were monounsaturated and 20.33–25.11% were polyunsaturated. The levels of δ- tocopherol (552.24–670.31 μg/g seed oils) and lutein (4.82–8.95 μg/g seed oils) differed in cultivars. The nine cultivars were varied in total phenolics, flavonoids, and free phenolic acids, but not in proanthocyanidins. Seed extracts of Hybrid #63, Tou Xin Hong, and Hybrid #72 showed stronger DPPH radical scavenging capacity, ORAC, and FRAP than others (p&lt;0.05). The Yanzhi #2 extracts exhibited a strong ACE-inhibitory activity, which was positively correlated with vanillic acid contents (r = 0.890, p = 0.001). It provides evidence on developing value-added utilization of radish seeds or seed fractions such as oil and flour as nutraceuticals or functional food ingredients.
