Methods of selecting plants having delayed or inhibited ripening or senescence

摘要

The present invention provides, inter alia, a method of obtaining plants which exhibit delayed or inhibited fruit ripening and/or vegetable tissue senescence comprising:(i) growing seedlings thereof in the presence of an auxin polar transport inhibitor and selecting those seedlings the hypocotyledon of which grows at an acute angle of less than about 70° to the horizontal; and/or-(ii) contacting the seeds of plants which have a low or reduced polar auxin transport with a conjugation inhibitory amount of an inhibitor of cytokinin-N7.9glycosyl conjugation and selecting from the thus contacted seeds those which germinate.
