Introducing the new crop vegetable chayote [Sechium edule (Jacq.) Swartz.] into Korea for climate change.
Chayote [Sechium edule (Jacq.) Swartz.], vegetable pear, is also known as Alligator pear and Buddha hand melon. The crop originates from high-temperature regions in tropical Central America. S. edule (Cucurbitaceae) is an herbaceous, monoecious, self-compatible, perennial vine in tropical regions, but an annual in temperate regions such as Korea. The single-seeded fruits are viviparous and variable in size, shape, color, pulp texture, and density of spines. Two varieties for skin color exist: green and white. These two varieties of chayote fruit were put in the growing chamber with dry soil for germination on February 9. They were transplanted to a non-heated plastic house on April 17. The first flowering date of green varieties was August 30, and that of the white was September 13. Plant growth, including number of nodes, length of internode, and leaf size, of the green variety was better than that of the white. Brix degree and hardness of fruit compared with the white showed that the green was larger and heavier. In 2012, the yield of the green was 23,520 fruits weighing 8047.8 kg, which was four times the yield obtained from the white, with 5560 fruits, comprising 1903.9 kg, 10 a-1.
