This experiment showed that certain varieties of red peppers had resistancy to excessive soil moisture. Sixteen varieties of red pepper were planted in 30㎝-pots, with controlled water levels: 5.5㎝, 11.0㎝, 16.5㎝, flooding on the surface (22.5㎝) and control. This experiment began on June 4th, the beginning of the wet season, and was continued until the death of the plant.
1. Flooding on the surface resulted in fading within two days after treatment and all varieties died after 3-4 days, 16.5㎝ flooding produced fading four days after, leaves became yellow and dropped slowly, and died 7 to 30 days after treatment, 11.0㎝ f.u. pots did not die, but growth of plants was poor and leaves slowly became yellow-pink, 5 days after treatment, and 5.5㎝ pots produced normal.
2. Root hairs of plants which were grown in 16.5 ㎝ f.u. and 11.0 f.u. and 11.0 f.u. pots were rare and formed rear the surface. In the intermediate parts of the pot a black-brown color change was noted in the roots, and epidermis were peeled off.
3. The higher the water levels the more flower-dmp, the less flower set, and the lower yields produced especially in 11.0㎝ f.u. pot and higher ;eater concentrations.
4. The resistant varietes to excessive soil moisture were DAKANOJUME and PENDURUM, next in resistance was SAE RED PEPPER, FOURTY-FOUR and CHUN AN, and POOT RED PEPPER, MASAN, NM 6-4 were not quite resistant.
5. Methods of preventing excessive moisture injury are:
(1) maintaining water levels of 5.5㎝ f. u. or lower,
(2) planting resistant varieties DAKANOJUME, PENDNRUM, SE RED PEPPER, and FOURTY-FOUR varieties.
