ABSTRACT Lethal yellowing (LY), a disease caused by a phytoplasma, is the most devastating disease affecting coconut (Cocos nucifera) in Mexico. Thousands of coconut palm trees have died on the Yucatan peninsula while plantations in Central America and on the Pacific coast of Mexico are severely threatened. Polymerase chain reaction assays enable(More)
The effect of gibberellic acid (GA3) was tested on germination of coconut zygotic embryos, their conversion into plantlets and ex vitro survival. There were four treatments consisting of 5 wk of culture in semi-solid medium or liquid medium, with or without GA3. Embryos were then transferred to GA3 free-liquid medium for the rest of a 32-wk culture.(More)
Plants of Tagetes erecta L. (marigold) cultivated in vitro in ventilated containers exhibited greater control of leaf water loss and increased survival in the field than plants cultivated in sealed containers. Increased field survival of plants cultivated in ventilated containers was attributed to higher levels of endogenous abscisic acid (ABA). Therefore,(More)
Germination of coconut (Cocos nucifera L.) zygotic embryos was tested in liquid or solid medium. Percent germination was greater when embryos were cultured in solid medium, particularly when embryos were placed with their micropyle end facing upwards in relation to the vial orientation, independently of orientation in relation to gravity. This occurred(More)
