Growth and development of thalli of P. yezocnsis are influenced by various environmental conditions. Apart from the temperature and light the nutrient is also a very important factor. The present paper deals with the relationship between the growth and the formation, discharge and adherence of monospores of thalli and nitrogenous fertilizer. The results of the experiment are summarized as follows:1. Thalli of porphyra growing in different marine environments require different (NH4)2SO4 contents. The consen-tration...

Growth and development of thalli of P. yezocnsis are influenced by various environmental conditions. Apart from the temperature and light the nutrient is also a very important factor. The present paper deals with the relationship between the growth and the formation, discharge and adherence of monospores of thalli and nitrogenous fertilizer. The results of the experiment are summarized as follows:1. Thalli of porphyra growing in different marine environments require different (NH4)2SO4 contents. The consen-tration of (NH4)2SO4 demanded by thalli of porphyra is lower in the poor region than in the fertile region.2. The nutrition condition for forming monospores of porpnyra thalli collected from both poor and fertile region are usually similar. More monospores are formed by thalli above the (NH4)2SO4 concentration of 10 mg/l, but few or none are formed below 1 mg/l. Therefore related to the concentration of (NH4)2SO4. The formation of monospores are clo-sely.In order to get more monospores, it would be necessary to keep a. certain concentration of (NH4)2SO4 in the medium.3. The quantity of the discharge and adherence varies with the number of monospores formed. The effect of the nutrient concentration on the discharge and adherence of monospores is not evident.4. The color of both the control and the 1 mg/l thalli will turn from purplish red to light green or candle yellow, but in 10-100 mg/l medium they remain purplish red.5. The vacuoles in vegetative cells are larger and more in number in both the control and the one in 1 mg/l medium. The vacuoles of the vegetative cells in 10-100 mg/l medium can hardly be seen. These phenomena agree with those in nature.

作者研究了(NH_4)_2SO_4的浓度对条斑紫菜生长和单孢子形成、放散与附着的影响。在室内培养条件下,条斑紫菜的生长和单孢子形成、放散、附着要求的营养条件不完全一致。当硫酸铵的浓度增加到一定量时紫菜的生长受到抑制;低浓度时,单孢子的放散、附着少;高浓度时,单孢子放散、附着的多。

This paper deals with the results of a study on ecology of the Porphyra haitanensis filaments and the techniques of their seedling breeding, which are as follows:1. The growth and development of the filaments are not affected by the summer water temperature (30℃) in mid and north sea waters of Zhejiang. It is possible by exchanging sea water of high temperature and distributing P of 24ppm in the late period to increase conchospores.2.

Turning the hanging breeding shells upside down periodically may decrease the difference of maturitycaused by the temperature and light differences. Covering the windows of the laboratory with black plastic sheetings is of major importance in facilitating the maturity of the filaments.

本文通过对坛紫菜丝状体生态及育苗高产措施的研究,结合对几处群众育苗生产的总结,得出下列结论。 1.在浙江中、北部,盛夏水温达到30℃,不影响丝状体的生长和发育。后期多换高温海水,施24ppm磷素,可以增产壳孢子。 2.吊挂培育贝壳定时掉头,可以减少温差和光差影响产生的成熟度差异。后期以黑塑料布遮窗缩光,是丝状体成熟的主要措施之一。 3.相对密度(与4℃水比)为1.013—1.015的海水,不影响生产性育苗。 4.用串长30cm,串距和棒距各5cm以上的吊挂培育优于平面培育,可提高壳孢子放散量85%,提早8天成熟。 5.老壳利用、自由丝状体接种育苗、贝壳渠道刺激等技术,均可增产壳孢子。

The turion is an sexless reproduction organ of potaniogeton crispus which resistances to unfavourable eclogical environment. When the pH value, light nutrient etc in the environment is beyond suitable value, the formation of the turion can be hastened, especially'effect of high pH value is obvious.The turion of newly forming have a resting period in which vary with water temperature and light. It is about fifty days at 22~25℃ in light. High temperature (>30℃) and darkness can lead to increase resting period, whereas lower temperature (13c) and red light can reduce resting, period.In sprite of light or darkness under water temperature is 2~35℃, pH3~ 10, salty is less than 11‰, the turions which already perform the resting period can germinate.

鳞枝是菹草抵御不良生境的一种延存器官。当环境中的pH、光照、营养盐等偏离正常值时,均可促进鳞枝的形成,但高pH的作用特别突出。 刚形成的鳞枝都有一个自发休眠期。休眠时间的长短依水温、光照而不同,在水温22~25℃有光照的条件下约为50天;高温(>30℃)、无光会延长其休眠期,低温(13℃)和红光刺激可使休眠期缩短。休眠期已满的鳞枝在水温2~35℃、pH3~10、盐度<11‰的环境中,无论光照条件如何均可萌发。
