摘要
营养液培养条件下,以甘蓝型油菜硼高效品种青油10号和偏高效品种宁油7号(DH系),硼低效品种Bakow和Tapidor(DH系)为材料,研究不同硼效率基因型苗期对硼、磷缺乏的反应。试验结果表明:缺磷条件下,青油10号和宁油7号长势显著好于Bakow和Tapidor,并且前者磷的含量和积累量显著高于后者;青油10号和宁油7号磷效率系数分别为0.480和0.497,显著大于Bakow(0.243)和Tapidor(0.287)。苗期硼高效品种表现磷高效性状;硼低效品种表现磷低效性状。硼高效和磷高效苗期具有一定的相关性。缺硼对硼低效品种地上部生长的影响显著大于缺磷对硼低效品种的影响。
Boron efficiency cultivars, Qingyou 10 and boron efficiency tendency cultivars, Ningyou 7 and boron inefficiency cultivars, Bakow and Tapidor were used to study the effect of boron and phosphorous deficiency on the growth in the seedlings by water culture experiment. Qingyou 10 and Ningyou 7 grew better than Bakow and Tapidor, and phosphorous content and accumulation of the former were more than the latter. Boron efficiency coefficients of Qingyou 10 and Ningyou 7 were respectively 0.480 and 0.497, whereas Bakow and Tapidor respectively 0.243 and 0.287. Results showed that boron efficiency cultivars and boron efficiency tendency cultivars behave P efficiency and boron inefficiency cultivars behave P inefficiency, which indicated that phosphorous efficiency was positive correlation with boron efficiency. Effects of boron deficiency were more than of phosphorous deficiency on the shoot of boron inefficiency cultivars.
