CHAPTER I
THE PROBLEM AND ITS BACKGROUND
Introduction
Nypa fruticans known as Nipa Palm in the Philippines is the only palm considered a mangrove in the Mangroves Biome. This species is a monotypic taxon, the only one in the genus Nypa. Nipa palms grow in soft mud and slow moving tidal and river waters that bring in nutrients. The palm can be found as far inland as the tide can deposit the floating nuts. Nypa fruticans, the Nipa palm, has a horizontal trunk that grows beneath the ground and only the leaves and flower stalk grow upwards above the surface. Thus, it is an unusual tree, and the leaves can extend up to 9 m (30 ft) in height. The Nipa Palm is one of the most important economic Philippine crops. It differs from most palms in the lack of an upright stem, trunkless, developing inflorescences at 1 meter height. The leaves are commonly use for thatching. Leaflets are used for making hats, baskets, mats, raincoats, wrappings for suman. The midribs are used for making brooms; the petioles for fuel.
Nipa is a monoecious palm, with stout, subterranean, trunkless and thornless rootstock. Leaves are at the ends of the rootstocks, large, rosette and compound, 5 to 10 meters long, arising from the stout underground stem (rhizome). Leaflets are numerous, rigid, lanceolate, up to 1 meter long, 2 to 7 cm centimeters wide. Male inflorescence is brown, erect, up to 1 meter high. Female inflorescence is stout, 1 meter high or less. Fruit is globose, nodding, up to 30 centimeters in diameter. Carpels are numerous, dark-brown, striate, smooth, 10 to 14 centimeters long, compressed, obovate. Seeds are hard, white, and as large as a hen's egg. It can be cultivated or wildcrafted. Nipa palm has many uses. Young seeds are edible. It is also a source of alcohol, sugar and vinegar. The fermented juice, tuba, is extensively use as beverage. Leaves are one of the most commonly used materials for thatching. Leaflets are used for making hats,
