Pili (Canarium ovatum) is a fruit-bearing tree with significant potential as a major export crop. As a tropical plant, it thrives in regions with evenly distributed rainfall, such as the Bicol region. The young fruits are green and turn purplish-black when fully ripe. While pili nuts are the most popular Bicolano product, the fruit's flesh is also used to make viands like Tampuyak, a delicacy in the Rinconada area. This versatility allows the pili tree to sustain the needs of various industries.
Expedite the Germination Process
Pili seeds are the primary means for sowing and cultivation. However, the natural germination process can be slow; according to the Bureau of Agricultural Research, seeds typically require an average of 57 days to germinate. This means it can take approximately 70 days after sowing for the plant to fully sprout and develop its first pair of young leaves.
To minimize the germination time, you can follow a simple technique. Using a bolo or similar tool, create a small hole on the spinal part of the pili seed before sowing it. The purpose of this hole is to facilitate the penetration of water and oxygen into the seed, as these two elements are crucial for germination to occur. By allowing easier access to water and oxygen, the seed's germination process can be accelerated.
Soil media used for your seed bed and soil bag
Plant nurseries throughout the region emphasize the importance of using high-quality soil for young, growing plants. The soil should possess favorable characteristics, including optimal texture, fertility, acidity, and water-holding capacity. Providing these conditions is essential for the healthy growth and development of young pili seedlings.
A recommended soil medium for seedbeds and polybags consists of a 1:1:1 ratio of the following components:
- Decomposed or carbonized rice hull
- Sand or animal manure
- Loam soil
This combination of organic and mineral components provides the necessary nutrients and physical support to meet the plants' needs.
Once the pili seeds have germinated, they should be transferred to soil bags. During the transplantation process, extreme care must be taken to avoid damaging the roots. Preserving the integrity of the root system is crucial for the continued health and vigor of the seedlings.
Practice pricking/indirect planting
Pricking is a technique commonly used in nurseries to gradually acclimatize seedlings to excessive sunlight. It involves exposing the seedlings to increasing amounts of sunlight over time.
After transferring the seedlings to soil bags, the process of pricking begins. On the first day, expose the seedlings to sunlight for at least two hours. The following day, increase the exposure time by an additional one to two hours. Continue this process of gradually extending the exposure time each day until the seedlings can tolerate a full day of sunlight.
By gradually exposing the seedlings to sunlight, this technique helps them adapt and build resilience to the intense sunlight they will encounter when transplanted into the field. This increases their chances of successful establishment and growth in their new environment.
One male of Pili per hectare
For optimal pollination and fruit set in pili trees, it is recommended to plant at least one male pili tree per hectare of female trees. Male pili trees produce the pollen necessary for fertilizing the female flowers and initiating fruit development. The presence of a male tree ensures a sufficient supply of pollen; without it, the female trees may fail to produce fruit or may have a significantly lower fruit set. Therefore, ensuring the inclusion of at least one male tree within each hectare is essential for achieving successful pollination and a high yield of pili fruits.
Since Pili is dioecious (meaning male and female flowers live on separate trees), telling them apart early is tough because they don't flower until they are about 3 to 5 years old. This is why many farmers prefer asexual propagation (like grafting)—it ensures you know the sex of the tree before you even plant it!
what exactly is the spinal part of a pili? where to make a hole?
ReplyDeleteMs. Ruby, The spinal part of pili seed is a tip of seed which is more snuffs (more sharp-pointed) than to other side. Actually, you can make a small hole either side as long as you can and you can't destruct the seed tissue. This will serves as nose and mouth of the seed for easily germination.
