This cactus is cultivated in Southeast Asian countries such as Vietnam, Thailand, Malaysia, Taiwan and the Philippines. The wide scale planting in Region I started in 2007 when the REFMAD farm in Brgy. Paayas, Burgos, Ilocos Norte established the first dragon cactus plantation in the region. Considering the climatic condition of the Ilocos, this crop is very adaptable and can be recommended in marginal upland areas and sand dunes. Planting dragon cactus can convert unproductive lands into productive ones. This crop is very suitable to goal 1 areas. Biology and Ecology Saniata is a perennial, epiphytic, climbing cactus with triangular, fleshy, jointed green stems and grows up to 25 to 50 years. The stem segments grow to about 6 meters long. Dragon cactus only blooms at night. The flowers are large and white, often called Moonflower or Queen of the Night. The normal flowering and production season of Saniata is from April to November. The Saniata fruit is bright pink/pale magenta color, and green-colored spine-like scales. The scales turn yellow as the fruit ripens. The fruit is non climactic or it does not undergo dramatic ripening change after maturity. The fruit can be harvested 30 days after fruit set. The fruit continues to grow in size until harvested, with no noticeable change in sugar content. Dragon cactus species 1. Hylocereus polyrhizus – red flesh with pink skin 2.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
