作者为瞭解像胶草根内醣与橡胶之关系,在1944,1945年进行了大田及砂耕试验,以了解植物不同生长期内橡胶草根内橡胶与醣之变化。大田试验于1944年春播种,11月开始收获,最初二月内橡胶量变化不大,如1944年11月5日含胶量为7.14％,12月5日为7.12％,1945年1月5日为6.79％。但此时醣变化很大,如1944年11月5日到12月5日。根内总醣量减少(14.1→11.33％),而单醣有增加(1.44→3.17％)。1944年12月5日到1945年1月5日醣的总含量继续降低,其中特别是菊糖,但单醣增加。 1945年1月5日到3月5日土壤结冰,植物冬眠,此时总醣量未见减少,但单醣降低约二倍。单醣的降低却有益於橡胶的增加,如此时橡胶量从6.79％增到11.26％。以上说明了卽使在冬天,橡胶草根内生物化学
In order to understand the relationship between g..blocked words .. root gum and rubber, we conducted field and sand-tillage experiments in 1944 and 1945 to understand the changes of rubber and sugar in rubber grass roots at different growth stages of plants. The field trials were sown in the spring of 1944 and started harvesting in November. The rubber volume did not change much in the first two months of the year, as shown in the plastic volume of 7.14% on November 5, 1944, of 7.12% on December 5, January 5, 1945 6.79%. But at this time the sugar varies greatly, as of November 5, 1944 to December 5, 1944. Total root sugar decreased (14.1 → 11.33%), while monosaccharides increased (1.44 → 3.17%). December 5, 1944 to January 5, 1945, the total sugar content continued to decline, especially inulin, but monosaccharides increased. January 5, 1945 to March 5 soil icing, plant hibernation, this time no decrease in total sugar, but about two times lower than the monosaccharide. The reduction of monosaccharides is beneficial to the increase of rubber, so the amount of rubber increased from 6.79% to 11.26%. The above illustrates the 卽 made in winter, rubber grass biochemistry
