Seed germination has recently reinvigorated interest, owing to its importance in the natural development
of plants and the cultivation of crops. However, germination of seeds, especially Coriandrum sativum
and Lathyrus odoratus, can sometimes be difficult or impossible due to multiple factors, such as the
condition of the seeds themself. The purpose of this study is to examine the effect of pre-treatment on
the germination of Coriandrum sativum and Lathyrus odoratus seeds. The experiment was set up in a
completely randomized design involving three replicates. The treatments were soaked in tap water for
48 hours (Type A), in tap water for 24 hours (Type B), 6% H2O2 (Type C), abrasion with sandpaper
(Type D), scarification with mortar and pestle (Type E), and control (no pre-treatment) (Type F). The
most suitable depth level for seed germination and seedling growth of Coriandrum sativum and
Lathyrus odoratus were also investigated. The results show that germination of Coriandrum sativum
was highest (93.3±6.67) when immersed in 6% hydrogen peroxide (H2O2), while the germination
percentage of Lathyrus odoratus was highest (46.7±17.64) when immersed in tap water for 48 hours.
Furthermore, Coriandrum sativum seedlings germinated efficiently at a depth of 2.0 cm, while seedlings
of Lathyrus odoratus have the highest germination percentage at 0.0 cm (control). Hence, this study
can provide useful information about the influence of pre-treatment and sowing depth on the
germination of these two plant species, which can directly improve the germination process.
