Tissue culture plant
In order to investigated the growth of tissue culture plants in Tainong No. 1'passionfruit (Passiflora edulis Sims × Passiflora edulis f. flavicarpa Deg.), own-rooted tissue culture plants, tissue culture scion grafted on the seedling rootstock of P. edulis f. foavicarpa Deg. and common scion grafted on the same rootstock were used as material in this syudy. Potted passionfruit plants were grown in field of Viticulture Research Station, NCHU in autumn of 1994, and their growth was investigated as well as the virus infection was traced. It was found that whether the diameter and length of the main shoot, number of shoots, number of nodes, fresh weight and length of shoot, total area and weight of leaves, number of flowers and fruits, root system and yield of tissue culture own-rooted and tissue culture grafting plants were longer, larger and more than common-grafting plants. The tissue culture owned-root plants had the highest products and their fresh weight of shoots and leaves was two times more than commom-grafting plants. Nevertheless the yield of per plant in tissue culture grafing plants was 1.5 time more than the tissue culture own-rooted plants and two times more than common-grafting plants. However the fruit size and quality of three tested plants did not show difference.
