Pilot Studies on Plant Growth and Fruit Production of Papaya in Two Different Facilities
Huang, S. H.
Papaya production in Taiwan is usually planted in
net house easily affected by unpredictable weather conditions such as typhoons
and heavy rain. A more wind resistant and rainproof facility is therefore
needed. In this study, we evaluated the growth and fruit production from papaya
cuttings in summer with in two different facilities, a plastic greenhouse and a
net house. Plants in plastic greenhouse grew more vigorously than those in the
net house, particularly during rainy season. The
plant height, stem and crown diameter, and number of leaves, nodes, and fruit were also greater in plastic greenhouse than in net house. Days to first flower and harvest, the node number of the first flower and fruit ,and the position of the first fruit were significantly fewer in plastic greenhouse, whereas the number of fruit and the yield were greater in the plastic greenhouse. There was no significant difference of the fruit quality in two facilities. However, further investigation of fruit storage indicated that the rate of rotting decay substantially reduced in papaya grown in the plastic greenhouse.
What is already known on this subject?
Most of the papaya productions in Taiwan are in the net houses and a few in open field.
What are the new findings?
This is the first report to evaluate the growth and fruit production of papaya from cuttings in two different facilities, plastic greenhouse and net house in Taiwan.
What is the expected impact on this field?
Papaya farmers will benefit by greenhouse cultivation from its protection against typhoons and heavy rain. The year-round production of papaya will be more stable and free from the threat of rain-born disease.
