ig. 2Effectsofwaterstressonstarchaccumulationinxylemofcarrot (200 ×) 2.2.2 carrot roots under water stress on starch accumulation in the phloem changes can be seen from Figure 3, different degrees of water stress on carrot root phloem changes in starch accumulation is smaller than the root xylem. As water stress increases,tory burch reva, the number of starch grains in root phloem gradually reduced, in particular, strong handling areas significantly reduced the number of starch grains, but weak in the handling area and processing area of the starch grains only slightly reduced in volume,tory burch outlet, is not very clear . Figure 3 of water stress on starch accumulation in carrot root phloem of I200 ×) Fig. 3Effectsofwaterstressonstarchaccumulationinph ~ emofcarrot (200 ×) 3 3.1 Conclusion and discussion of water stress on root soluble sugar metabolism in young roots of carrot under normal water supply, sucrose levels than higher levels of glucose and fructose, respectively, both 1 .6-fold and 2.7-fold. Under water stress,timberland portugal, sucrose levels were significantly lower, the greater the stress level, the lower the level of sucrose, while glucose and fructose levels are subsequently increased under water stress in the high concentration of glucose and fructose were sugar CT_ - ABRICULTURAE92BOREILI-SIHICa. . . . . . - CHINA AGRICULTURAL UNIVERSITY 22 volumes of 3.9 times and 2.8 times. Note the strong water stress conditions, may accelerate the conversion of sucrose to produce more glucose and fructose. 3.2 Water stress and changes in starch accumulation in roots of water in normal circumstances,ugg schuhe, the carrot root starch content is at a high level, but under water stress, especially in high water stress, however, reduced the number and size of starch and become smaller, indicating strong water stress active part of starch hydrolysis may occur,ghd piastre, so that sugar levels have been improved to increase the cell's osmotic potential, to meet the growth in arid environments. |
