Biosynthesis of ascorbic acid in irradiated and unirradiated germinating rapeseed cultivars was studied at ambient room temperature (20-35 degrees C). Appreciable quantities of ascorbic acid (19.8-24.1 mg/100 g) were detected in the seeds and synthesis of this vitamin increased significantly (three fold) with increasing germination time depending upon rapeseed cultivars (p < 0.05). Soaking of seeds in tap water (1:2) for 24 hours resulted in the decrease of the vitamin in each case. Among the radiation treatments (0.05-0.20 kGy), maximum amounts of ascorbic acid were found in 0.10 kGy (342.1 mg/100 g dry weight) and 0.15 kGy (113.8 mg/100 g wet weight) samples after 96 hours of germination. An overall significant linear relation (r = 0.96) was observed between vitamin biosynthesis and germination time upto 96 hours in rapeseed.
在环境室温（20 - 35摄氏度）下，对辐照和未辐照的发芽油菜品种中抗坏血酸的生物合成进行了研究。在种子中检测到了相当数量的抗坏血酸（19.8 - 24.1毫克/100克），并且这种维生素的合成随着发芽时间的增加而显著增加（三倍），这取决于油菜品种（p < 0.05）。将种子在自来水中按1:2浸泡24小时，在每种情况下都会导致维生素含量下降。在辐射处理（0.05 - 0.20千戈瑞）中，发芽96小时后，在0.10千戈瑞（342.1毫克/100克干重）和0.15千戈瑞（113.8毫克/100克湿重）的样品中发现了最大量的抗坏血酸。在油菜籽中，直到96小时，维生素生物合成与发芽时间之间观察到总体显著的线性关系（r = 0.96）。
