Single-step and nested polymerase chain reactions (PCR) were used to determine the presence of Candidatus Liberibacter asiaticus, the phloem-limited bacterial pathogen of Huanglongbing (HLB), in leaves of wampee [Clausena lansium (Lour.) Skeels], lemon [Citrus limon (L.) Burm.] and several other citrus species. Specific PCR products were obtained when single-step PCR and nested PCR were used to...

During the major part of growth in oranges, lemons, and avocados, chlorophyll does not limit photosynthesis at constant light intensities (5). as might be expected. However, during the period of color change in fruits it would be po...
