有关紫菜壳孢子、单孢子的附着,用条斑紫菜观察了其附着生长机制,又对附着同照度、温度、氯度及水流等的关系进行了研究探讨。 1.壳孢子在放出时同时释放大量的粘液,它帮助孢子上浮,向基质接触。此外,放出的单孢子粘液较少。 2.照度对附着的影响,照度在5,000—10,000米烛时附着多,在3,000米烛以下的低照度时附着量渐渐减少,黑暗时几乎不附着。 3.温度的影响,两种孢子都是在20°、25℃条件下附着良好,10℃以下附着不好。 4.氯度和附着的关系,氯度值14.5、18.6‰时附着数多,11.5‰以下附着数减少。 5.水流与附着的关系,在90厘米/秒以下范围水流越快,附着数越多,可以认为其理由是由于在高速时孢子接触机会多的缘故。
With regard to the attachment of porphyra spores and monospores, the mechanism of attachment and growth was observed with Porphyra yezoensis, and the relationship between attachment and illumination, temperature, chlorinity and water flow was studied. 1. Aspergillus spores release large amounts of mucus at the same time, which helps the spores to float and contact the matrix. In addition, the release of monospore mucus less. 2. The effect of illumination on the attachment, the illuminance of 5,000-10,000 meters when the candle attached more than 3,000 meters in the candle below the amount of adhesion decreased, almost no adhesion in the dark. 3. Temperature effects, the two spores are in 20 °, 25 ° C under the conditions of good adhesion, 10 ° C below the adhesion is not good. 4. The relationship between chlorine and adhesion, the chlorine value of 14.5,18.6 ‰ attached more, less than 11.5 ‰ less attached. 5. Water flow and attachment, the faster the water flow in the range of 90 cm / s or less, the more the number of attachment, the reason is that due to the high chance of exposure to spores at high speed.
