The pigments that give the seed its particular color seem to be localized in the pericarp tissues.^ The mode of inheritance of seed color is of immediate practical importance to those breeding lettuce for disease resistance, climatic adaptation, and desirable commercial charact...
متن کاملClimate and host plant characteristics effects on lepidopteran caterpillar abundance on Miconia ferruginata DC and Miconia pohliana Cogn (Melastomataceae).
Folivore cerrado caterpillars are found on their host species in low frequencies, which vary between plants and throughout the year. We analysed the effects of climatic variation and of the characteristics of two host species (Miconia, Melastomataceae) on caterpillar abundance. The work was carried out in a cerrado sensu stricto area in Brasília, Federal District, Brazil, from May 1998 to Septe...
