Thus, my study focused on research of the effect of different salts on absorption, transport, accumulation, and the function in halophyte Suaeda Salsa and nonhalophyte Nicotiana tabacum L.

Conventional forest breeding is constrained by its long reproductive cycle, which includes long juvenile period, and by its complex reproductive characteristics, such as self-incompatibility and a high degree of heterozygosis. Gene transformation has played an important role in woody plant improvement, which can shorten breeding period and breed varieties with high salt tolerance.

随着分子生物学技术的发展,从生植物中分离出抗基因,导入林木,获得抗品种;况且林木由于其较长的幼年期,常规育种有明显的局限性,而通过转基因可以在较短时间内获得高抗品种,缩短育种周期,因此开展林木抗育种具有重要的意义。

We also found that the content of Na(superscript +), K(superscript +) and proline in leaves varied with different treated days. Under all treatments, the absorption of Na(superscript +) increased and the content of proline in leaves decreased with the prolonging of treated days. The absorption of K(superscript +) measured on the 7th day and the 21st day increased and was restrained on the 14th day, which lead to the decline of K(superscript +)/Na(superscript +) ratio. While the content of praline measured on the 14th day remarkably increased with the increase of salinity. Our experiment indicated the live oak seems to adapt the salt stress by increasing the absorption of K(superscript +) during the earliest and late stages of salt stress and accumulating proline in leaves during the middle stage of salt stress.

同时发现,胁迫处理不同时期对叶片脯氨酸含量和Na、K含量的影响各不相同,在处理7d和21d时,叶片对Na和K的吸收量均有增加,使K/Na维持相对稳定的比值,而脯氨酸含量随NaCl质量质量浓度的增加减少;在处理第14d时,对Na吸收增加的同时,抑制了对K的吸收,导致K/Na比值随NaCl质量质量浓度的增加而迅速下降,而此时叶片脯氨酸含量随着质量质量浓度的增加而迅速增加,表明在胁迫早期和晚期,弗栎可能通过增加对K的吸收以减轻Na离子毒害效应,而在胁迫中期,叶片积累脯氨酸是适应胁迫的方式之。

Sodium phosphate salts,which mainly include sodium orthophosphate,sodium pyrophosphate,sodium polyphosphate,and sodium metaphosphate,are the largest produced and consumed phosphate products in industrial phosphates.Their technical exploitation and market development are both relatively mature.

磷酸钠是工业磷酸中产量最大、消费量最多的磷化工产品,其技术开发与市场发展都比较成熟,主要有正磷酸钠、焦磷酸钠、聚磷酸钠和偏磷酸钠

A simple estimation method for molar Gibbs free energy and enthalpy of formation for complex oxysalt minerals is proposed. Complex oxysalt minerals are divided into complex oxysalt minerals with water and complex oxysalt minerals without water. Complex oxysalt minerals without water can be considered as the composite of acidic oxides and alkaline oxides, so their molar Gibbs free energy or molar enthalpy of formation can be calculated by the summation of molar Gibbs free energy or molar enthalpy of formation of the acidic oxides and alkaline oxides which are combined into the complex compounds.

提出了一种复杂含氧矿物的摩尔生成Gibbs自由能和摩尔生成焓的简单估算方法,并把复杂含氧矿物分为不含水复杂含氧矿物和含水复杂含氧矿物,不含水复杂含氧矿物可以看作是酸性氧化物和碱性氧化物组成的物质,其摩尔生成Gibbs自由能或摩尔生成焓都可以看作是酸性氧化物和碱性氧化物复合成的化合物摩尔生成Gibbs自由能或摩尔生成焓之和。
