Strongylodon macrobotrys, A. Gray from the family Fabacee/Leguminosae Papilonidae (bean family). Its common names are Jade vine, Emerald creeper (English) Tayabak (Tagalaog), Phuong yok (Bangkok).The pale green foliage consists of three leaflets. The claw-shaped flowers are carried in pendent trusses or pseudoracemes of 75 or more flowers and can reach as much as 3 m long. The turquoise flower color is similar to some forms of the minerals turquoise and jade, varying from blue-green to mint green. The short, oblong, fleshy seedpods are up to 15 cm long and contain up to 12 seeds.
The plant grows beside streams in damp forests, or in ravines.The inflorescences are only produced by mature vines. Each individual bloom resembles a stout-bodied butterfly with folded wings; they have evolved certain modifications to allow them to be pollinated by a species of bat that hangs upside down on the inflorescence to drink its nectar.The flowers are also visited by a species of wasp, and are home to a species of butterfly.
There are several other species of Strongylodon, but the superficially similar red jade vine, Mucuna bennetti, is a species belonging to a different genus,Mucuna. It seems to be endemic to the Philippines and is usually found in forests.Propagation has always been difficult. It is considered an endangered species due to the destruction of its habitat and the decrease of its natural pollinators. There seems to be a method of marcotting through mature woody stems. It is best planted in ground near a water source, but not inundated. The vine entwines itself through the trunk and branches of trees and the leaves spread over the canopy. The flowers hang like clusters of grapes. http://en.wikipedia.org/wiki/Strongylodon_macrobotrys

| my self propagated jade vine from my college thesis |

| In the wild, the Philippine Jade Vine is pollinated by bats. The bats apply pressure at the base of the petal, which releases pollen from the tip. I am fortunate enough to have these wild flower in front of our home. |
I have been so amazed at these majestic flower since I first saw this. I used this as a subject of my thesis " Protocol for In Vitro Propagation of jade Vine (Strongylodon macrobotrys A. Gray). Regeneration of Jade vine through tissue culture obtained callus, shoots and roots. Three auxins and two cytokinins were examined for their effect on callus, shoots and roots development of tissue culture. Shoots, nodes and internodes as explants were cultured in a media in the light and dark condition. Activated charcoal was also added to a number of culture media.
Callus induction in shoots, nodes and internodes was best observed in a media without charcoal kept in light condition. Callus formation was observed four days after inoculation. maximum shoot bud induction was best observed in a media without charcoal kept in light condition, ten days after inoculation. Root initiation was best achieve in shoot explants in a media with kinetin ans IBA with charcoal cultured in dark condition, four days after inoculation. To avoid bacterial and fungal growth, which is detrimental to culture growth, explants were initially surface sterilized in an aqueous solution with liquid detergent for fifteen minutes. After rinsing with water, the tissues were immersed in liquid detergent and zonrox for not more than ninety minutes.
Collection of Jade vine fruits during its abundance should be undertaken and used as source of explants. Flowers could also be tried as explants in case seeds are not available since a number of flowers are usually produced but not all of them developed into fruits. Germinated seeds at the culture medium gave the best response for the growth of culture. The use of shoot explants ws proven the best explants as compared to nodes and internodes.
To further improve this study, the following are recommended:
1. try growing media to enhance the callus growth as well as the shoot and root formation;
2. perform experiments to further validate the effects of using light and dark conditions for shoot and root formation;
3. treatments to lessen the browning of explants and occurrence of death after subculture must be included; and
4. additional focus on the precise sterilization procedure for Jade vine tissues to lessen the percentage of contamination should be made.
Significance of the study
The study conducted on the in vitro propagtion of Jade vine serves as an initial step into the conservation of the species. Clonal propagation or rapid and large-scale multiplication of Jade vine from "superior" stock plant can be obtained. The method allows for large amount of material to be preserved in small area. It overcomes the destruction of the species due to environmental hazards as well as for the protection against natural disorders.
Traditional tree improvement through seeds has been found to be slower, compared to the gains through cloning of selected genotypes. Farm forestry and forest plantations look for an increased productivity through supply of high yielding, disease resistant, fast growing and site specific planting stocks (Gaspara et al., 2005).
The results of this study will also provide baseline information and serve as reference for related inquiries and problems for other interested researchers and stakeholders.
The jade vine is cultivated as an ornamental plant for landscaping purposes.
I am more than willing to share my experiences in cultivating jade vine and help in the conservation and propagation of Jade vine. The rainforests of the Philippines are disappearing at an alarming rate – originally the islands were almost completely forested, but a 1988 survey estimated that only 20 percent of the forest remained.
