Characterization of carob germplasm (Ceratonia siliquaL.) in Sicily
SummarySixteen carob cultivars were studied to evaluate pulp and seed yield with regard to endosperm percentage, to determine the overall degree of polymorphism of the characters and to detect similarities among cultivars. Bean size and numbers of normal and aborted seeds were characters with a certain degree of polymorphism. The low between-year variability observed suggests that differences in the variables could be attributed to genetic factors. A high year-to-year variation was observed only for the number of aborted seeds. Seed characteristics showed small changes both between years and among cultivars. Out of all the variables, PCA identified four principal components that explained m…
Rearing of Prays citri on callus derived from lemon stigma and style culture
A new method for rearing the citrus flower moth (Prays citri Mill.) (Lepidoptera, Yponomeutidae) on lemon [Citrus limon (L.) Burm.] callus is reported. In the present research callus (an undifferentiated mass of plant cells that can be grown under sterile conditions on an artificial medium in vitro) was induced from lemon stigma and style explants cultured on Murashige and Skoog (MS) medium supplemented with 500 mg l -1 malt extract, 13.3 μM 6-benzylaminopurine, and 146 mM sucrose. Also somatic embryogenesis and plant regeneration were obtained from the cultures of styles and stigmas of lemon. Adults were obtained from larvae on infested flowers collected in the field. Different oviposition…
