In this study, matured seeds of collected from the identified superior mother in different location will be used. Five dipterocarps and other indigenous timber species found in Ilocos Norte will be evaluated. The component activities will be conducted at the MMSU Central Nursery from January 2013-December 2015. The assessment of the following activities: pre-germination treatment, potting media, fertilizer trial, watering and hardening-off practices will be done in a continuing process in a way that the promising results from the preceding activities will be integrated in the subsequent activities.

The following activities below will be laid-out using the appropriate statistical designs and tools and will be replicated three times.

Acty 1. Germination characteristics and early growth performance of selected dipterocarps and timber indigenous tree species

Acty 2. Growth performance and survival of seed-grown dipterocarps and timber indigenous tree species to different potting media

Acty 3. Survival and growth performance of seed-grown dipterocarps and premium indigenous tree species to various rates of fertilizers and GA3 application

Acty 4. Quality and vigor of seed-grown dipterocarps and premium indigenous tree species to different hardening-off practices

 

For this study, it is expected to establish cost effective propagation techniques of seed-grown timber species

Acty 1. Ideal pre-sowing treatments and storage techniques

Acty 2. Suitable potting media

Acty 3. Appropriate nutrient requirement

Acty 4. Ideal hardening practices of seed-grown timber producing species
