Abstract

|
|
The objectives of the study is to determine the effects of temperature and light on the contact coiling of cucumber tendril over supporting materials and to select suitable supporting materials.
1. When polyethylene net (PEN) was used for supporting material the contact coiling rate of cucumber tendril was shown very high, approximately 100%, during the period of June to September whereas it was lower than 50% during the period of October to May of coming year.
2. The speed of tendril elongation and the rate of contact and free coiling were higher at high temperatures and under high light intensity conditions.
3. Cucumber tendrils reacted very sensitively to the growing temperature with regard to the movement of contact coiling. The speed of contact coiling was promoted by high light intensity and long day conditions.
4. Marked differences were observed in the contact coiling rate depending on the kinds of supporting materials. The contact coiling rate was higher when the plant material (bamboo) was used as compared to the synthetic material (PEN).
5. Contact coiling rate of tendrils of cucumber as well as oriental melon was around 36%, whereas it was about 9516 for pumpkin and pea.
