This study was conducted to evaluate the effect of pepper (pipiemento
variety), and eggplant (Dara variety) seed's treatment on germination
characteristics, and the impact of eggplant seeds treatment on seedling quality.
The seeds were treated for
24 hours in glass containers, in which the ratio of
seeds to the applied media was 1:5, the concentration of the mineral solution
was 0.1%, while the concentration of each of GA3 and the organic nutrient
solution was 0.01%.
The media were continuously aerated by passing a current of pure oxygen
(O2), at sufficient pressure to homogenously mix the seeds in the media. The
seeds were dried up after 24 hours of treatment to remove the excess moisture.
Seeds were germinated in Petri dishes, and soil-full containers to assess the
germinability, and seed vigor. The eggplant seeds were also sown in peat-moss
containing pots (8 cm indiameter) to study the influence of treatment on
seedling quality.
The results showed that treatment efficiency depends on the nature of the
used media, and crop. In addition, it has been revealed that the aeration of
media enhanced the germination, accelerated the seedling growth, and
improved their quality.
The present investigation was carried out at the nursery of Agricultural faculty- Tishreen
University, during 2016-2017, to evaluate the best organic culture medium for the seedling
production of Zinnia (Zinnia elegans) and Stock (Matthiolaincana)
with the lowest costs.
Seven different mediums were experimented (Turf, waste mushroom compost, farm waste
compost and their combinations).
The results showed some differences in chemical and physical characters of experimented
mediums. This differences had an impact on germination parameters (seed germination
percentage, speed of germination, daily germination) and seedling quality (seedling length,
collar diameter, fresh and dray weight, percentage of dray matter).
The results indicated the mediums consisting of turf (T1), waste mushroom compost with
turf (T6) and waste mushroom compost with farm waste compost (T7) gave the best
germination rate and the highest quality of seedling.
Data showed as well that T3 and T7 treatments realized the lowest costs and higher
economic profit than other treatments.
