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 experiment was carried out to assess the germinability and seedling
growth rate of some treated vegetable seeds (i.e. onion, carrot, and tomato) with
aerated - aqueous solutions.
Seeds were treated for 24 hours with 0.1% of both succinic acid
and
nutrient solution, and the seeds to medium ratio was 1:5.
The soaking solution was continuously aerated by an air pump. At the end
of treatment, the seeds were dried up at room temperature to eliminate the
excess superficial moisture.
