“…4e, k, q). This indicated that AsA-treatment seeds could be kept higher vitality by maintaining the membranes integrity, and similar results have been reported in some species such as pea (Hernandez and Almansam, 2002), Arabidopsis thaliana (Wójcik and Tukiendorf, 2011) and Eragrostis ciliaris (Zehra et al, 2012). Moreover, CAT, GR and APX activities in AsA treatment seeds were significantly improved (Fig.…”

This study determined the effects of exogenous ascorbic acid (AsA) treatment on germination, membrane lipid peroxidation, activities of antioxidant enzymes and ultra-structure of embryo cells of Siberian wildrye (Elymus sibiricus L.) seeds with different moisture contents (4%, 10% and 16%) after ageing at 45°C for 48 h. Germination percentage and activities of enzymes declined, electrical conductivity value of seeds increased significantly as moisture content increased from 4% to 16%. However, ascorbic acid treatment had protective effects on alleviating the damage of ageing to seeds membrane integrity and structure of mitochondria, which was in accordance with the decrease of electrical conductivity and malondialdehyde (MDA) content, especially for seeds with 10% moisture content. Ascorbic acid treatment significantly (P<0.05) inhibited the loss of seed germination at 10% moisture content, and correspondingly electrical conductivity decreased and activities of catalase (CAT), ascorbate peroxidase (APX) and glutathione reductase (GR) improved. In addition, ultra structure observation of embryo cells showed that serious damage occurred in seeds with 16% moisture content, including the broken cellular and nuclear membrane, pyknotic nucleolus and swollen mitochondria. Although activities of CAT, APX and GR were improved by the exogenous AsA, it had no obviously protective effect on integrity of membrane system and mitochondria. Seed moisture of Siberian wildrye played a vital role in the function of AsA, which provided an efficient treatment to deal with the antioxidant effects of storage and ageing at seed moisture of 10%.

Influences of discharge voltage on wheat seed vitality were investigated in a dielectric barrier discharge (DBD) plasma system at atmospheric pressure and temperature. Six different treatments were designed, and their discharge voltages were 0.0, 9.0, 11.0, 13.0, 15.0, and 17.0 kV, respectively. Fifty seeds were exposed to the DBD plasma atmosphere with an air flow rate of 1.5 L min for 4 min in each treatment, and then the DBD plasma-treated seeds were prepared for germination in several Petri dishes. Each treatment was repeated three times. Germination indexes, growth indexes, surface topography, water uptake, permeability, and α-amylase activity were measured. DBD plasma treatment at appropriate energy levels had positive effects on wheat seed germination and seedling growth. The germination potential, germination index, and vigor index significantly increased by 31.4%, 13.9%, and 54.6% after DBD treatment at 11.0 kV, respectively, in comparison to the control. Shoot length, root length, dry weight, and fresh weight also significantly increased after the DBD plasma treatment. The seed coat was softened and cracks were observed, systematization of the protein was strengthened, and amount of free starch grain increased after the DBD plasma treatment. Water uptake, relative electroconductivity, soluble protein, and α-amylase activity of the wheat seed were also significantly improved after the DBD plasma treatment. Roles of active species and ultraviolet radiation generated in the DBD plasma process in wheat seed germination and seedling growth are proposed.

Seed germination and seedling growth of the annual halophyte species Suaeda japonica Makino were investigated in response to variable salinity of sediment pore water. The germination percentage of S. japonica’s soft brown seeds, which are dominant among dimorphic seeds, decreased with an increase in salinity, although germination was still observed at 1200‐mM NaCl concentration. The germination percentage and germination speed observed in April were higher than those observed in December when treated with sediment water with 400–1200 mM of NaCl concentrations. These data suggest that S. japonica seedlings could be established on sediments that experience high temperatures. Germination recovery of S. japonica seeds transferred from 600‐mM NaCl containing sediment (seawater equivalent) was lowest among 0–1200‐mM NaCl treatments, implying the low tolerance of seawater conditions of S. japonica seeds. Seeds germinated in 900‐ to 1200‐mM NaCl medium showed poor growth, but survived, in hypersaline conditions, and exhibited improvement in growth upon transfer to lower salinity.
