Effect of cultivation conditions on biotin contents in green and yellow vegetables

研究了栽培条件对青菜和黄菜生物素含量的影响。我们的研究强烈表明，植物中生物素的生物合成会随着栽培条件的变化而波动，特别是日照的量。这将导致绿色蔬菜中生物素含量的季节差异。冬季低日照地区绿色蔬菜生物素含量的季节差异尚需进一步研究。

We investigated the effect of cultivation conditions on biotin contents in green and yellow vegetables. Our study strongly suggest that biotin biosynthesis in plants fluctuates responding to the cultivation conditions, especially the amount of insolation. This will lead to the seasonal differences of biotin contents in green vegetables. It will be needed to clarify the seasonal differences of biotin contents in green vegetables at regions of low amount of insolation in winter.
