A mating design,including full-sib and half-sib Catalpa bungei was *** germination ability was *** temperature,soaking and lighting time and pretreatment that could influence on Catalpa bungei seed germination were *** result showed that the difference of germination rate and energy among different mating combinations was extremely *** influence of the individual plant to the germination rate was lower than that of different *** germination rate of the combination *** and *** was always *** germination rate and energy of two set of reciprocal crosses were very *** germination rate was the highest for soaking the seed for 24 hours at a constant temperature of 25 ℃ then germinating it at a changing temperature 20-30 ℃,the difference was *** result,an 8-hour-long lighting daily was more advantaged for the germination of the seed than that in a completely dark condition;the germinating rate of the seed stored at a temperature of 5 ℃ for a week after soaking is also much higher than that stored at a low temperature.
