摘要: The observation that the seeds of succulent fruits such as tomato fail to germinate whilst they are in intact fruit, but capable immediate germination if removed, washed and planted a moist medium, must have aroused curiosity many horticulturalists botanists past. Thus, thirteenth century Albertus Magnus observed pear apple seed less readily fruit than when removed (Kockemann 1936b). According Oppenheimer (1922a, b) it was Molisch who first suggested juices fleshy retard because presence inhibiting substances (see also 1922, p. 297). Subsequently has been established do, fact, contain which markedly inhibitory growth extracted applied suitable test objects. number species inhibitors detected is now considerable (Evenari 1949, Moewus et al. 1951, Niemann 1952) may be present various parts including non-succulent pericarp tissue, endosperm, testa, embryo.
