中文摘要：

在实验室条件下,研究了不同温度、光照强度和盐度对海柏（Polyopes polyideoides）果孢子的放散及附着的影响。结果表明：温度10~26℃的条件下,海柏果孢子均能够完成放散附着;18℃时,海柏果孢子放散附着速度最快且总量最大,而当温度低于5℃或者高于30℃时,海柏果孢子的放散附着受到抑制,几乎不放散附着;海柏果孢子放散附着的适宜光照条件为80？mol/（m2·s）,光照强度过高时海柏果孢子的放散附着明显受到抑制;盐度为22~36之间利于果孢子的放散附着,当盐度低于8,高于40的时候,海柏果孢子由于受到了盐胁迫,几乎不放散及附着。

英文摘要：

In this study, the effects of temperature, light intensity and salinity on the carpospores releasing and at-tachment ofPolyopes polyideoides were studied. The results indicated that： （1） within the range of 10-26℃,P. polyideoides carpospores were able to complete releasing and attachment; especially, at 18℃, the peaks of releasing and attachment ofP. polyideoides were very high and the speed was very fast; when the temperature is lower than 5℃ or higher than 30℃, the carpospores releasing and attachment ofP.polyideoides were repressed, almost no releas-ing and attachment. （2） The optimum light intensity for the carpospores releasing and attachment ofP. polyideoides was 80μmol/（m2·s）. When the irradiance is too high, the releasing and attachment ofP. polyideoides carpospores were significantly repressed. （3） Salinity conditions （22-36） are conducive to carpospores releasing and attachment and there is no significant difference within this salinity range,but when the salinity is less than 8 more than 40, as the carpospores ofP. polyideoideswasunder the salt stress, almost no releasing and attachment.
