We report the possibility to modify the wetting properties of the surfaces of a diversity of seeds including: lentils (Lens culinaris), beans (Phaseolus vulgaris) and wheat (Triticum, species C9) by cold radiofrequency air plasma treatment. Air plasma treatment leads to the dramatic decrease in the apparent contact angle. Moreover, the speed of germination and yield (germination rate) of seeds ...

Halogeton glomeratus (Bieb.) C.A. Mey (Chenopodiaceae) is an annual forb that is widely distributed in mixed desert shrub, salt desert shrub and pinyon-juniper communities of northern Utah. Halogeton glomeratus seeds gave only 78% germination in distilled water. Fusicoccin (FC) had some effects in partially alleviating innate dormancy while other chemicals had no effect. Seed germination was in...

Eryngium maritimum is a coastal plant of the Apiaceae family. This species is threatened in several countries where it reaches the northern limits of its distribution area. Existing populations in the Baltic Region and Scandinavia are potentially affected by the low efficiency of its generative reproduction. We studied physiological aspects of its germination and dormancy breaking requirements ...

Seed germination plays an important role in determining the composition and regeneration of plant populations (Stipa breviflora). However, the influencing factors and strategies employed for seed germination in desert grasslands under grazing remain unknown. Therefore, in this study, the reproductive allocation, seed density, seed properties, and corresponding seed germination rates of S. brevi...

As a kind of ephemeral plant, Lepidium apetalum Willd. in northern XinJiang shows special responsible characteristics to temperature during the germination: low temperature stratification could improve germination rate and homogeneity of L.apetalum seeds. But it could not germinate and be at stagnation stage under 4°C, while this phenomenon could be removed by the treatment with 25°C for 45 min...

this study was aimed to study the ways of removing dormancy period and accelerating pre-sowing tuber germination to provide simple tools to apply by farmers. for this purpose, intact tubers, exposed tubers to released ethylene and sliced tubers were examined in respect to germination characters, bud length, starch, anthocyanin and chlorophyll contents and amylase activity. relative amount of an...

an experiment was conducted to determine the aging mechanism in safflower seed using natural aging treatment (storing seed at room temperature for six years) and accelerated aging ( incubating the seed at 41?c and close to 100% relative humidity for 4 ,8 and 12 days). the results indicated that both natural and accelerated aging reduced germination percentage, seed vigor and activity of catalas...
