摘要
以香稻品种桂香占、品14和品15为材料,采用盆栽试验,研究了基施氯化镧100 mg.kg-1土壤处理对水稻糙米香气含量、籽粒脯氨酸含量及其脯氨酸氧化酶活性的影响。试验结果表明,氯化镧处理显著提高3个香稻品种糙米的香气含量和籽粒脯氨酸氧化酶的活性,而降低3个香稻品种籽粒脯氨酸含量;氯化镧处理提高品14和品15的剑叶脯氨酸含量而降低桂香占剑叶的脯氨酸含量。
A pot experiment was conducted in late season in 2007 to study the effect of basal application of LaCl3 at 100 mg per 1 kg soil on aroma content in brown riee, proline content in grain and proline oxidase activity by using three aromatic rice varieties Guixiangzhan, Pin14 and Pin15. The results showed that there was significant difference in aroma content in brown rice and increased praline oxidase activities among 3 aromatic rice varieties. LaCl3 reduced the proline content in grain. Morever,it decreased the proline contents in flag leaf of Guixiangzhan while these increased in Pin14 and Pin15.
