carotenes 中文意思是什麼
carotenes
解釋
胡蘿卜素-
With development and maturation of citrus fruit, chlorophyll content of citrus fruit peel decreased, being acompanied by a gradual decrease in a - carotene and p - carotene which are known to be in the upstream of carotenoid biosynthesis pathway. the decrease continued up to complete vanishment of the carotenes. on the other hand, p - cryptoxanthin, p - citraurin and zeaxanthin that are in the downstream of carotenoid biosynthesis pathway increased steadily and became the principal carotenoid components
隨著柑橘果實發育和成熟，果皮葉綠素含量下降，與此同時，位於類胡蘿卜素生物合成途徑上游的-胡蘿卜素、 -胡蘿卜素等胡蘿卜素成分逐漸下降直至消失，而在類胡蘿卜素生物合成途徑下游的-隱黃質、 -檸烏素、玉米黃素等葉黃素成分逐漸上升，使得類胡蘿卜素總量先略微下降后迅速上升；果實褪綠並呈現其特徵色澤。 -
There are over 600 known carotenoids ; they are split into two classes, xanthophylls and carotenes
有超過600種已知的類胡蘿卜素，可以分為兩類：葉黃素和胡蘿卜素。 -
The experimental results showed that the yield and quality of the tubers were improved by inoculation with mycorrhizal fungi. the isolates beg 168, gsp4 and beg 141 increased sweet potato tuber yield by 10 %. reducing sugar content and total carotenes were increased in isolates gsp4 and beg 141 by mycorrhizal inoculation
田間小區試驗的結果顯示，接種am真菌顯著提高了甘薯的產量和品質，其中beg168 ， gsp4和beg141的效應較高，增產了10以上；接種gsp4 、 beg141還提高了紅興335的可溶性總糖和胡蘿卜素含量。 -
There is great difference between the content of carotenes of different parts in different varieties : the content of carotenes of phloem is ' higher than xylem ' s to a great extent, and the results showed a descending trend of the content of carotenes from the top of carrot to lower parts
所以對這些品種建議提早採收，以便胡蘿卜素含量保持在較高的水平。胡蘿卜次生韌皮部中的胡蘿卜素含量極顯著的高於次生木質部，胡蘿卜肉質根中自上而下胡蘿素含量呈現遞減的趨勢，胡蘿卜素在胡蘿卜中主要分佈於次生韌皮部和肉質根的上部。 -
In this phase, we should control the fertilizer at a good level in order to get good output the percentage of xylem of nevis and nigel are the least, and die content of carotenes of nevis and nigel are the highest, among the five varieties of carrots
在供試的五個胡蘿卜品種中，心往所佔比例以品種nevis和nigel最小，胡蘿卜素含量以nevis和mgelt高，綜合其它品質因素，以nevis和nige的品質較佳。 -
As for the accumulation of carotenoids in varieties of carrots, the content of carotenes of nigel and nevis got to the highest level when they were harvested, but the content of carotenes of nandrin, cascade and xin heitian wuchun got to their summit before harvesting, then decreased
不同品種胡蘿卜在肉質根膨大過程中類胡蘿卜素的積累狀況是不同的，品種nigel 、 nevis的胡蘿卜素含量（ -胡蘿卜素和-胡蘿卜素）在採收時達到最大值，而的品種nandirn 、 cascade 、新黑田五寸則在採收前達到最大值。 -
In this study, varieties of carrots were used as experimental material, including nigel, nevis, nandrin, cascade and xin heitian wuchun. the research was focused on the analysis of carotenoids in carrot by high performance liquid chromatography ( hplc ). the content of lycopene, a - carotene and p - carotene during growing and the content of carotenes in different parts of different varieties were measured, in order to study the difference of the development of the content of carotenes among varieties, and try to study during which period carotenes was accumulated mostly in different varieties
本試驗以不同品種胡蘿卜（品種nigel 、 nevis 、 nandrin 、 cascade和新黑田五寸）為試驗材料，用hplc分析各品種胡蘿卜在其肉質根膨大過程中番茄紅素、 -胡蘿卜素和-胡蘿卜素積累的動態變化；不同品種蘿卜不同部位胡蘿卜素的含量；不同品種胡蘿卜中各胡蘿卜素所佔比例的差異，試圖研究不同品種胡蘿卜在肉質根膨大過程中，類胡蘿卜素形成及大量積累的主要時期以及不同品種胡蘿卜類胡蘿卜素形成之間的差異；胡蘿卜中類胡蘿卜素的分佈狀況，以及胡蘿卜中類胡蘿卜素含量與胡蘿卜色澤的相關性。
