The study aimed at investigating the effect of pre-sowing treatments on the germination and seedling vigour of Guava (Var. Allahabad Safeda) seeds. The pre- sowing treatments were made up cold and hot water soaking, manual scarification with sand paper, electronic scarification, different concentration of sulphuric acid, H2O2, CaOCl2 along with control. The treated and control seeds were placed for germination in top of the paper method. Twenty five days after sowing the result revealed that seeds soaked with CaOCl2 2% for 12 hrs. registered highest germination of 41 per cent followed by seed treated with H2SO4 200ml/kg for 15 minutes (40%). The control seeds gave only 10 per cent germination. Vigour index values shows significant differences among the treatments. The highest vigour index values of 119 were recorded in the seeds treated with H2SO4 200ml/kg for 10 minutes. The lowest vigour index value of 16 was recorded in control treatment. The results showed that treating the seeds with CaOCl2 2% for 12 hrs (or) treated with H2SO4 200ml/kg for 10 (or) 15 minutes was the most effective pre-sowing treatment for the germination and seedling vigour of Guava seeds.

A laboratory study was undertaken to know the effect of seed polymer coating with Zn and Fe nanoparticles (NPs) at different concentration (10, 25, 50, 100, 250, 500, 750 and 1000 ppm) in pigeonpea at Department of Seed Science and Technology, UAS, Raichur. Among the treatments seed polymer coating with Zn NPs at 750 ppm recorded significantly higher seed germination (96.00 %), seedling length (26.63 cm), seedling dry weight (85.00 mg), speed of germination (32.95), field emergence (89.67 %), seedling vigour index (2556), dehydrogenase activity (0.975 OD value) and α-amylase activity (25.67 mm) and lowest abnormal seedlings (2.50 %) over their bulk forms and control followed by Fe and Zn NPs at 500 ppm. However, in contrast to beneficial effects, these NPs also shown inhibitory effect on germination and seedling growth at higher concentration (nano Zn >750 ppm and nano Fe > 500 ppm). Hence, from the results it is concluded that Zn NPs at 750 ppm can be used to enhance quality of the pigeonpea seeds.

Seed priming has proved to be an effective method in imparting stress tolerance to plants using natural and/or synthetic compounds to treat the seeds before germination. The present study was designed to investigate the physiological mechanism of seed priming with ZnSO4 (osmopriming) and distilled water (hydropriming) on sugar beet genotypes (‘Shokofa’, ‘Sina’, ‘Paya’, ‘Turbata’, and ‘Aria’) germination indices, seedling growth parameters, and biochemical properties under salinity stress (0, 2, 5, and 12 dS/m NaCl). A significant reduction in germination percentage (33.23%), germination rate (77.2%), chlorophyll a, b, and total contents (43.9, 31.9, and 39.9%, respectively) while, a significant increase in radical, plumule, and seedling length (57.1, 44.4, and 51.2%, respectively), seedling vigour index (48.9%), superoxide dismutase activity (61.3%), proline (54.0%) and sugar (56.3%) contents were achieved at 12 dS/m NaCl in compared to the control treatment. Seed hydropriming and osmopriming caused significant improvements in photosynthetic pigments, antioxidant enzyme activity, and proline content reflected in high germination percentage and rate as well as seedling vigour index and reduced mean germination time under salinity. ‘Paya’ and ‘Aria’ genotypes had a superiority according to the germination percentage and seedling vigour index, respectively. The hydropriming of ‘Paya’ genotype resulted in the highest germination percentage (95%) under high level of salinity (12 dS/m) which 11.84% increase compared to the control treatment. Hydropriming of ‘Sina’ seeds showed the highest chlorophyll a and total, and carotenoids under non-stress conditions (22.89, 31.65, and 2116.6 µg/g FW). Also, hydropriming by increases chlorophyll b content led to the modulation of the negative effects of high salinity stress (12 dS/m). In conclusion, different seed priming treatments in sugar beet seeds improved the salinity tolerance by physiological characteristics nonetheless hydropriming was the most effective treatment to get higher germination indices in ‘Paya’ and ‘Aria’ genotypes.

An experiment was conducted to study the effect of pre-sowing treatments on germination of Abies spectabilis commonly called as “Talispatra” - an important high level conifer of Western Himalayan region. The seeds of Abies spectabilis collected from Kalabagh near Churdhar area of Shimla district (H.P.) were given different pre-sowing treatments of cold moist stratification in sand for 1 to 4 weeks and control (untreated seeds) to study their effect on germination behaviour and seedling vigour index. Significant differences were observed in germination per cent and seedling vigour index of seeds subjected to different pre-sowing treatments. The maximum germination per cent (42.00%) was recorded in seeds treated with cold moist stratification treatment in sand for 1 week followed by 36.00 per cent germination recorded for control (untreated seeds). The minimum germination per cent (19.50%) was recorded in seeds treated with cold moist stratification treatment in sand for 4 weeks. The findings of the present investigation revealed that Abies spectabilis seeds do not possess any dormancy and the poor germination is primarily due to presence of large number of empty seeds.

This study was conducted to evaluate the effect of different methods of seed pre-treatment on germination of two indigenous tree species, Sweet dattock and Indian jujube (Detarium microcarpum and Ziziphus mauritiana). The experiment is carried out at the Tree Seedlings Nursery of Faculty of Agriculture, Kebbi State University of Science and Technology, Aleiro. Treatments consisted of Boiled water (100ºC) for 10 minutes, 20 minutes and 30 minutes; three levels of diluted sulphuric acid (H2S04) soaking time for 10minutes, 20 minutes and 30 minutes; Seed scarification and control. The treatments were arranged in Completely Randomized Design (CRD) with three replications per treatment. Results revealed that the seed of Sweet dattock (Detarium microcarpum) soaked in hot water at 1000 C for 30 minutes exhibited the best germination percentage (100.00±0.00) within four (96 hours) days. This is followed by hot water treatment for 10 minutes and sulphuric acid treatment for 20 minutes which gave the same germination percentage of 93.33±11.54 within 4 (96 hours) days. The seeds under control treatment gave the least germination percentage of 86.67±11.54 and took a longer period to germinate (eleven days.) Indian jujube (Ziziphus maurtiana) seeds on the other hand, gave the highest germination percentage (93.33±5.77) with scarification, followed by soaking in hot water for 30minutes (46.57±11.54), while the lowest germination percentage was recorded for seeds in the untreated control (3.33±5.77). Based on the result, pre-treatment of Sweet dattock (Detarium microcarpum) seed with hot water at 1000 C for 30 minutes and scarification of Indian jujube (Ziziphus maurtiana) seed is recommended for effective germination.
