Abstract:
... Attempts to assess the possibility of deriving all energy from renewable sources typically deal only with the aggregate amount of energy required, and do not consider the implications and difficulties arising from the need for differing forms of energy. In a 100% renewable system some of these forms will have to be provided by conversion from others, mostly from electricity. Conversion involves in ...

Abstract:
... The non-climacteric ripening characteristics, including delayed peel coloration and pulp softening, of 'Jen-Ju Bar' ('JJB') guava (Psidium guajava L.) is a result of a reduction in the usually massive amount of ethylene produced during the ripening stage. To elucidate the underlying physiological mechanism, four cDNA clones of ACC synthase (PgACS1 and PgACS2) and ACC oxidase (PgACO1 and PgACO2), t ...

Abstract:
... In the history of strawberry breeding, selection for aroma was mainly conducted to avoid untypical flavor notes. The depleted aroma patterns of modern cultivars resulted from fixation on breeding goals like high yield, large, firm and optically attractive fruit. Genetic erosion was clearly demonstrated in comparative studies using old and modern cultivars. Wild species introgression can serve to i ...
