“…Besides, corky pericarps are usually rubbed in commercial sugar beet seeds, and the degrees of rubbing are not always consistent. In the case of solid matrix priming (SMP) , Taylor et al (1988) pointed out that the osmotic potential of penetrated solution from seeds greatly affected the effect of SMP because the amount of applied water for SMP was very small. It is widely known that the pericarp of sugar beet contains watersoluble substances preventing germination.…”

“…As a result, halopriming with salt solution, osmopriming with polythe yield of sugar beets grown under a drilling system is ethylene glycol solution (Khan et al, 1983) and solid usually much lower than that of transplanted beets matrix priming with damped solid minerals that have a (Fletcher, 1984;West, 1984). Thus, for sugar beet high water-holding capacity (Taylor et al, 1988; Rush, farmers in Japan to use a drilling system, it is essential to 1991). Priming experiments have also been undertaken improve the yield.…”

“…However, osmo-conditioning also has some negative effect by intensifying the development of seed-born fungi and the fungi appearance in the course of osmo-conditioning. The solid matrix priming (SMP) is based on regulation of water availability to seeds by means of a solid substance (Taylor et al 1988). When the treatment is applied to seeds of low vigour level, SMP is very effective (Khan et al 1990) as opposed to osmo-conditioning with PEG, which in this case proves to be ineffective (Tylkowska and Biniek 1996).…”

The effect of two priming techniques: hardening (prehydration treatment) and solid matrix priming (SMP) was studied on the seeds of two parsley varieties (Cukrowa and Berlińska) in 3-year laboratory experiments. On the images obtained from scanning electron microscope (SEM) there is a parsley embryo developing during germination up to the moment of radicle emergence. On the surface of primed seeds, in particular using the hardening method, lateral cracks are visible. The respiratory activity of primed seeds was similar to that of non-primed in the period of initial 24 h of germination, but significantly higher after 48 h. As compared to non primed seeds solid matrix priming significantly increased the percentage and the speed of germination. Nevertheless, pelleting reduced the positive effect of priming on the germination ability, without affecting the germination speed. After 18 months of storage, the vigour of primed seeds, particularly through hardening, had significantly decreased.

“…Several appropriate materials, such as PEG, polyethylene glycol (Heydecker, 1974), salts (Levitt and Hamm, 1943), rock powder (Taylor et al, 1988), and porous materials (Miura and Khan, 1990;Khan et al, 1992) The addition of extra water to the potting mixture for 5 days (Fig. 1), induced earlier and faster emergence and gave a higher number of seeds to emerge within 20 days of transfer to a growth chamber than in the control.…”

SummaryIndividual seeds of Malabar spinach or Malabar nightshade Basella alba L. were sown in plastic cells of flats with a commercial potting mixture ("Shinkenbyokun, type 140") with three different water contents. The moisture levels were adjusted by adding 16, 52, and 100g of water to 500g potting mixture. After sowing, the plastic flats were stored for different periods at 15 and 25°C and then watered, and transferred to growth chambers controlled at 30°C (day) and 20°C (night), and an 8-hr photoperiod to induce emergence.Seeds, in flats with 52g water and stored at 15°C for 10 days, began to emerge 2 days after transfer to the growth chambers and attained 63 to 70% emergence within 5 days. Seeds without the post-sown treatment (control) emerged 5 to 6 days after transfer; the number of seeds emerging gradually increased and reached 23 to 24% 20 days after transfer. A high percentage of seeds emerged in the post-sown treatment of 52g water at 25°C for 5 days. Results of the two treatments showed that the rate of emergence was faster and the length of the hypocotyl was less variable in the post-sown treatment of 52g water kept at 15°C for 10 days.Therefore, the optimal treatment of improving the emergence of Malabar spinach seeds is to sow them in a potting mixture with a moisture content equivalent to 52g water per 500g mixture (water content of 41 to 45%) and chill them at 15°C for 10 days.
