查询词典 apices

It was shown that the root elongation was inhibited and the malonaldehyde content in root apices and the antioxidase activities of root apices were increased under Al stress (30 μmol/L), while the effects of Al were significantly alleviated by the addition of Si (1.4 mmol/L). Moreover, both Si added before Al treatment and Si added simultaneously with Al treatment could alleviate these effects. On the other hand, the cultivar of Seca was shown to be more sensitive to Al than other cultivars in the absent of Si, while Al-resistance distinction among the cultivars of stylosanthes turned to be non-significant in the present of Si in the pre-cultured solution or both pre-cultured and Al-treatment solutions.

研究结果表明，在铝(30 μmol/L)胁迫条件下柱花草根伸长受阻、根尖丙二醛含量和抗氧化酶活性显著增加，而硅(1.4 mmol/L)处理增加根中硅的含量而降低了铝对根伸长、MDA含量和抗氧化酶活性的影响，且铝处理前12h供给的硅和前处理溶液及铝溶液中均加硅处理的影响均显著；在不加硅条件下西卡品种的耐铝性显著低于其它品种，而经硅预处理的植株和在预处理及铝处理期间均供应硅的植株的耐铝性不同品种间的差异不显著。

Shoot apices of calla lily were used for in vitro culture. Multiplication rate on lateral bud formation was low. There were two patterns of multiplication rates with serial subcultures among three calla lily cultivars.

In this study, aluminum resistance screening was conducted firstly by treating BX10 and BL2 sprouts in a simple B/Ca (0.5mmol/L CaCl〓+8μmol/L H〓BO〓, pH=4. 5) solution with or without AlCl〓, and then the root length, apices concentrations of aluminum and callose were determined every 6 hours after treatment.

结果总结如下：(1)BX10抗铝性的鉴定：在已知BX10是一个典型的磷高效品种，其耐低磷能力显著高于BL2的基础上进一步作了这两个品种抗铝能力的鉴定。

Leaves crowded on caudex or on branch apices of caudex, in a rosette.

在块根，在一莲座丛的分枝尖上的在块根或上的叶密集。

It was found that the Polymeric Titanic Sulfate has a apices of decalescence at 150℃,and it changed into ivory-white powder of when sintering to 335℃, and the chemical formatis(SO_4); then it changed into yellow powder when sintering to 595℃, the Ti(SO_4)_2 andTiO_2 are found from XRD.
