Effect of Pre-Sowing Treatments on Mamalis (<i>Pittosporum pentandrum</i> Blanco Merr.) Seeds Germination under Nursery Condition

Abstract

Seeds were subjected to three different pre-sowing seed treatments: immersion in lukewarm water for 2 hours, immersion in concentrated sulfuric acid (H 2 SO 4 ) for 5 minutes, hilar removal, and a control in which the seeds were sown without being treated. The experiment was laid out in the Completely Randomized Design (CRD) with four replicates and 60 seeds per treatment. Seeds were sown in an improvised Seedbox in October 2019. Germination was monitored daily for one month. The results showed that Mamalis seeds treated with lukewarm water have the earliest germination of twelve days, with a germination percentage of 66.67%. The germination rate of another treatment ranges from 0 -44 percent, compared to 45 percent for the control treatment. It seems prudent to conclude that to enhance the vegetative propagation methods is to soaking in warm water at 37.5˚C for 2 hours could provide the best growth.

Quantifying Arborescent Flora Diversity in a Secondary Forest Ecosystem: A Comprehensive Assessment in Nambalan, Mayantoc, Tarlac, Philippines

“…Fern.-Vill, and Pittosporum pentandrum (Blanco) Merr. It is noteworthy that all the recorded flowering plant species, like Pittosporum pentandrum has the ability to suppress and inhibit the growth of Cogon (Imperata cylindrica) and Talahib (Saccharum spontaneum); it also produces good soil cover in denuded areas, which is useful for vegetative rehabilitation of degraded areas [49]. This emphasizes the rich native floral diversity present within the study area and highlights the importance of conserving these native plant species to maintain the ecological balance and support local ecosystems.…”
