与cultivar相关的网络例句 [注：此内容来源于网络，仅供参考]

In the seedlings time, the content of chlorophyll decreased by the deficiency of B, but the content of chlorophyll in the high efficiency cultivar decreased slowly than that of the low efficiency cultivar. This suggested that the leaves of the high efficiency cultivar can capture more light energy and the photosynthetic rate of the high efficiency cultivar decreased slowly. In the bolting time and blooming time, after two weeks of B deficiency treatment, the content of chlorophyll in the top leaves of the high efficiency cultivar decreased, and in the late time, the content of chlorophyll decreased slowly. But, the content of chlorophyll in the bellow leaves of the two cultivars had little changes. The reason may be that B in the high efficiency cultivar distributed to the propagative organ in the late growth, and the leaves were short of B.

苗期，缺硼导致甘蓝型油菜色素含量降低，且高效品种色素含量下降的幅度小于低效品种，表明营养生长阶段，同等程度的缺硼条件下，高效品种叶片对光能的收集能力以及光合速率下降的程度相对较小；苔期和花期，在两周的缺硼处理后，高效品种上部叶色素含量依然呈下降趋势，但随着生育期的推移，其下降幅度减小；而高效品种下部叶和低效品种叶片含量变化不大，可能是甘蓝型油菜进入生殖生长阶段后，高效品种将硼更多地分配到繁殖器官，而其叶片却承受了相对较大的缺硼胁迫。

The light compensation point of remontant cultivar was lower than that of once flowering cultivar, and the light saturation point of two-crop cultivar was higher than that of once flowering cultivar.

二次花品种与一次花品种相比，具有较低的光补偿点和较高的光饱合点，说明二次花品种对光的要求范围较一次花品种广，具有更广泛的生态适应性。

The Φ(subscript PSⅡ), Fv/Fm and qP were increased but qN was decreased with increasing of chlorophyll a, the rate of heat dissipation was increased with the increasing of chlorophyll b, and the carotinoid increasing enhanced the rate of heat dissipation of dryland and carbon assimilation of irrigated cultivar The Φ(subscript PSⅡ) and qN of dryland cultivar treated by control were higher than that of irrigated cultivar in jointing stage significant, indicating that the characteristics of drought-resistantce of winter wheat could be displayed in the jointing stage, and the drought-resistant capability could be increased by enhancing the practical photochemistry efficiency and heat dissipation in jointing stage.

拔节期对照处理的旱地品种的Φ和qN显著高于水地品种，在该时期品种抗旱性差异表现较为明显，能够通过提高光合机构实际光化学效率和热耗散来增强光合机构对干旱的适应能力。

cultivar：(栽培)品种

在七十五年来,由这二十种野 "种"又产生了超过三十种的"栽培品种"(Cultivar),即人工培养出来的品种. 各野种之间是可以随便交配的,一种Saintpaulia与另一种配种,是轻而易举之事,甚至一些业余研究杂种繁殖的人,也可以把家中所种的两三种品种互相交配.

cultivar：品种

在七十五年来,由这二十种野"种"又产生了超过三十种的"栽培品种"(Cultivar),即人工培养出来的品种. 各野种之间是由于一般科学家及著名以科学为题材著作的作家对有关进化论的名词及术语的混淆含糊,对所谓证明也分别不清,

cultivar：栽培种

第二种则指不同族群(population),或是不同品种(breed)及栽培种(cultivar)之间的相互交配,此意义经常使用于动物及植物的育种上.
