Cruz and barangay Tuban and planted some 3,000 mangrove propagules only recently.
The Cajigals encouraged those who joined the activity to maintain and nurture the bamboo propagules, saying the bamboo species they planted will serve as sources of planting materials for future reforestation activities.
Seaweed farming has also been proven to be the most viable and sustainable source of income, because the supply of propagules can easily be replenished from cuttings, without depleting the natural marine resources.
She added that their mangrove nursery in Bued has more than 5,000 available propagules ready for planting.
"Last year, we produced more than 145 million pieces of planting materials using native and fast-growing species -- in addition, we produced 3.3 million bamboo culms or cuttings and 1.72 million mangrove propagules and beach forest tree seedlings," he added.
Initially, somatic embryogenic propagules were used for synthetic seed preparation (Murashige, 1977).
He said that, based on the agreement between the DENR and the DPWH, the contractor would be required to plant at least 100 propagules for every mangrove that would die during the earthwork activities.
2); b) Plantlets forced to develop by destroying the apical growing point of vegetative plants (gouging) and stimulating growth of lateral buds; c) Plantlets (propagules) formed instead of flowers and fruitlets by plant treatment with chlorflurenol at flower initiation (HEPTON, 2003).
Phytophthora propagules responsible for much of the known host-to-host spread are normally ovoid or pyriform in shape and are called sporangia (fig.
According to the researchers, one likely function of stems would be to enable the greater dispersion of offspring, which rangeomorphs produced by expelling small propagules. The tallest organisms were surrounded by the largest clusters of offspring, suggesting that the benefit of height was not more food, but a greater chance of colonising an area.
Dispersion of organisms by water flow in macrophyte mats may increase the delivery of propagules in sites far from the area where the organisms originated (Barrat-Segretain, 1996).
