中文摘要:
      关于海带所含主要化学成分的季节变化,国外自1938年以来已有若干研究报道发表,在我国年来对于大连产及青岛产海带所含主要化学成分的季节变化也开始进行了较有系统的分析工作,这一作,对于海带的食用、工业利用和生理生化的研究,都是很有意义的。我国人工培育的一年生海带,由分苗期的不同,分夏苗和秋苗两种,在三月间,秋苗仅长50余厘米,而夏苗已长一米多,其化学成分的长可能也有所不同。本文仅就海带秋苗的水分、灰分、碘、褐藻酸和粗蛋白含量的季节变化进行了分析。
英文摘要:
      1. The water, ash (from March to December, 1962,except July),iodine, alginic acid and crude protein (form March to August, 1962, except July) contents of Laminaria japonica Aresch from Tsingtav were determined. The water content was rather high in young specimens, It was as high as 94.86%in March, and diminished gradually afterwards. In young specimens, the ash content was comparatively low, it was only 17.88% in March, but increased rapidly in April, declined in Augoat, and again increased in Decemher. As they grew, the iedine content increased monthly up to 1.13%in Angust, which is higloer than that reported by previous warkers.Tlee aeasonai rariativns o, crude protein content cvmparcd with those of alginic avid content hova shown an inverse tendency. 2.The seasonal variations in opt. pH, opt. temperature and the activity of catalase in Laminaria japonica Areach were studied. The verified results are shown in Figs. 2 and 3.The opt. pH of catalase was 8.68一9.18 and may he greater than pH 9.18. The opt. temperature of the catalase was 10-20℃. The seasonal changes of the temperature of the sea water had no in,luence upon the vpt.pH and the opt. temperature of catalasc. The maximum value of catalase activity in August is identical with that of the intensity of photosynthesis.
