“…Furthermore, seeds treated with Zn (1%) have also shown significant effect on shoot and root length contributing to the vigour of the seedlings over the control (Table 1). Similar findings were also reported by Stratu and Costica (2015) in Cucumis melo. The pre-sowing treatment with zinc increases the concentration of Zn in endosperm and contributes to the increase in shoot length through auxin metabolism.…”

King-chilli (Capsicum spp) is a high value spice crop of the North Eastern India. Although crop is having a great demand in national and international market due to its richness in capsaicin and oleoresin contents, however, it is grown in some pockets of the region on small scale due to specific climatic requirement, poor seed germination and traditional cultivation practices. Keeping these in view, the present investigation was undertaken to study the storage life, effect of temperature and pre-sowing seed treatment on germination behaviour and maturity indices of the crop for seed purpose. The results indicated that seeds of King-chilli remain viable and can be stored up to one year. The maximum seed germination (69.67%) was recorded at first month of the storage and then gradually decreased with increase in storage period with least (0.33%) at the 18 months after storage. The optimum temperature for seed germination was 25-30°C. The synchronous, higher germination (65.67%) and vigorous seedling (1477.58) can be raised by pre-sowing seed treatment with KNO3 (5%) for 24 hr. The seeds of dried pod had shown highest germination (68.77%) and seedling vigour (611.37) when the pods are harvested at fully developed yellow stage. However, seed from red ripe fresh pods with 7 days resting period was found ideal for higher germination and vigour over the seeds from the dried pods. Hence, commercial growers can store the seeds of King-chilli for one year and raise vigour seedlings with maximum germination by pre-sowing seed treatment with KNO3 (5%).

“…The application of Zn, commonly available via the leaf, improves germination, vigor, and viability of the seeds, in addition to increasing the levels of carbohydrates and proteins (albumin, globulins, glutenins, and prolamins) (PANDEY et al, 2013). Several studies have found that seeds treated with Zn in appropriate doses promote positive effects on the physiological potential of seeds in adverse conditions, especially in soils with Zn deficiency (FAROOQ et al, 2012;PROM-U-THAI et al, 2012); however, in toxic doses, they can affect the elongation of the main and secondary roots (STRATU;COSTICĂ, 2015).…”

Micronutrients are used in small amounts by plants and changes in metabolic processes of seeds can improve germination and vigor; however, little is known about the effects of the combination of Zn, Co, and Mo on corn seeds. Thus, the objective of this study was to evaluate the effects of the application of Zn, Co, and Mo on the physiological potential of corn seeds of different sizes and levels of vigor. A randomized 2×2×3 factorial design was adopted, with two levels of vigor (high and low), two seed sizes (18 and 22 mm), and three doses of liquid fertilizer containing micronutrients (0, 2, and 4 mL kg-1). The physiological potential of the seeds was evaluated based on germination and vigor tests. High vigor corn seeds had greater physiological potential compared to low vigor seeds. Regarding size, small seeds (18 mm) had higher percentages of germination and vigor than the large seeds (22 mm). Seed treatment with micronutrients (Co, Mn, and Zn) resulted in improved emergence in the field, shoot length, and dry mass of large and small seeds with the application dose of 2 mL kg-1, and the application dose of 4 mL kg-1 enhanced emergence in the field of large seeds and germination after the cold test of low vigor seeds of both sizes.

This study deals with the determination of germinability of black medick (Medicago lupulina L.) seeds in conditions of different drought intensity induced by different concentrations of PEG 8000 solutions (0.2; 0.4; 0.6 mol). Four batches of seed were tested (Ekola 2–5). At the same time, the influence of boron, some other elements (N, P, K, Ca, Mg, Zn, Cu, Mn) and compounds (starch, lipids and sugars) contents in black medick seeds on their germinability (percentages of germinated, dead and hard seeds) was evaluated. The effect of drought was manifested by germination which was reduced max. by 8% as compared with the control variant and was only partially significant. Statistically significant (P < 0.01) negative correlations (R = − 0.64) were recorded between germinability and the boron content in the seeds, and positive correlations were found between the percentages of hard seeds and the boron content in the seeds. The results show that the higher content of boron in the seeds of black medick increases the proportion of hard seeds at the expense of the germinated seeds percentages.
