1.\u3000Ecological characteristics of edible lotus. \u3000<\/strong><\/p>\n\n\n\n

Elongation and enlargement of rhizome in edible lotus are controlled by photoperiod, that is to say, rhizome elongates and enlarges under long and short days, respectively. However, early maturing cultivars grown in plastic tunnels and greenhouses exhibit rhizome enlargement even in long-day conditions. This suggests the presence of other factors controlling rhizome elongation\/enlargement in edible lotus. We study the effects of various growth environments on the elongation and enlargement of edible lotus rhizomes and clarify the ecological characteristics of edible lotus.<\/p>\n<\/div>\n\n\n\n

2.\u3000Establishment of the edible lotus protected cultivation system.<\/strong><\/p>\n\n\n\n

In general, cultivation of edible lotus requires a large growth area, which makes difficult to control the growth environment. If it becomes possible to cultivate edible lotus in a small container, productivity can be expected to increase by controlling of growth environment in greenhouses. Therefore, we aim to explore and breed cultivars that are suitable for cultivation in a small growth area and establish stable production techniques by controlling of growth environment.<\/p>\n<\/div>\n\n\n\n

 In recent years, increased temperatures caused by global warming have adversely affected the quality and yield of leafy and fruit vegetables. To solve these issues, we study to explore and breed cultivars that can be grown under high temperature conditions and develop stable production techniques by controlling of growth environment.<\/p>\n\n\n\n
