ABSTRACT

The impact of chilling injury on crop production is just as great as freezing. Numerous efforts have been made to overcome the chilling problem in agriculture, for example, breeding for early vigor in maize, modifying cultural practices to enable survival of tomato seedlings after early transplanting in the field, or application of chemicals to alleviate chilling injury in rice. Tests showed that GLK-8903 has a high potential to alleviate seedlings from chilling injury. Sprayed with GLK-8903 immediately after removal from the chilling environment, leaves of treated plants remained green and healthy without necrosis. Plants showed protection from chilling injury 2 to 3 days after spraying; however, 4 to 5 days after a spray, GLK-8903 was less effective. The optimum concentrations of GLK-8903 for bean treatment in the controlled environment are between 0.05 and 0.5%. Both common bean and bell pepper are important economic crops.
