Plant Growth
种植增长
The growth of plants is a dynamic, integrated process that is expressed in the pattern of development of individual organs.
植物的增长是动态,完整的处理那被表达在发展的模式的个体的器官.
Early studies of plant tolerance to environmental stresses by Wood and Petrie were of the effects upon this pattern of the plant responses.
植物的早学习允许误差到环境论压力由木头和Petrie是的效果在植物的这模式之上反应.
Wood initiated physiological studies of the ontogeny of the very tolerant Australian native flora and these were continued by other workers.
木头开始个体发生的生理学的学习的非常宽容的澳大利亚的本地人植物群和这些被继续由其他工人.
Much of the earlier work was reviewed by Wood.
许多更早工作被评论由木头.
He found that the morphological characters of the Australian xerophytic flora that he studied differed from mesophytic flora in much the same manner as did plant associations in other climatic regions.
他发现那morphological澳大利亚的xerophytic的字符植物群那他故意的与mesophytic不同植物群在几乎一样的方法作为植物联合在其他气候上的区域.
But, the schlerophyll leaves of Australian xerophytes had a high degree of lignification as a result of a partial diversion of the normal carbohydrate flux, that resulted in an accumulation of tannins.
但是,schlerophyll澳大利亚的干燥地带植物的树叶有高度木质化因为普通碳水化合物的偏袒的转移流出,那引起丹宁酸的积聚 .
In the tomentose succulent leaves of the and saltbush steppes the diversion was to pentosan formation.
在tomentose多汁的树叶的和saltbush西伯利亚大草原转移是到 pentosan构造.
This led to detailed biochemical studies of responses to water shortage and focussed attention on sulphur containing amino acids and protein metabolism by Wood.
这导致详细的生物化学的研究的回应水不足和焦点注意在硫磺包含 amino酸类和蛋白质新陈代谢由木头.
Levitt went further and studied sulphydryls as an important factor in frost hardiness.
Levitt进一步做和故意的sulphydryls作为重要的因素在霜 hardiness.
In these early studies Wood concluded that "Water does not exert an effect as such, that is, as a molecular species through its activity".
在这些早学习木头结束那"水不发挥结果照此,那是,当分子的种通过它的活动".
However, that view has required modification, as will be pointed out here from the ontogenetic studies undertaken on a range of plant tolerances.
无论如何,那查看已需要调整,当将被指出这里从ontogenetic学习从事在植物的范围允许误差.
Previous volumes have described the many climatic changes to which agricultural plants have adapted to varying degrees in widely diverse regions,
早先容量描述了农业植物适应了不同程度在广泛不同的地区的许多高潮变动,
and have pointed to the anticipated trends in climate to which mankind is contributing and which will fundamentally affect the productivity of his agriculture.
并且指向了被期望的趋向在人类贡献并且根本上将影响他的农业生产力的气候对
Climatic change not only affects aerial environment but leaves its imprint upon the edaphic environment in which plants grow.
气候上的改变环境不仅影响航空但是树叶它的铭刻在土壤的环境之上在哪一个种植成长.
There are numerous examples: The aerial deposits of soil from the Gobi Desert now constitute the highly fertile loessial soils of China;
有数目众多的例子:航空存放的土壤从Gobi放弃现在构成高多产的 loessial中国的土壤 ;
The impoverished soils of Australia result from aeons of leaching during previous periods of higher rainfall;
使澳大利亚的土壤贫穷起因于永世的过滤正当更高的降雨的前一时期 ;
The nutrient leached soils of the lush Amazon region lead to shallow rooted tropical vegetation;
营养的过滤多青草的亚马逊河的土壤区域导致浅的生根的热带植物;
The fertile river deltas of East China;
多产的河东方的中国的三角洲 ;
Thailand and the Nile River are the product of heavy rains in higher regions upstream;
泰国和尼罗河是重雨的产品在更高的区域向上游;
and The cyclic salt of Australian soils results from thousands of years of wind borne sea spray deposited far inland from coastal regions.
并且澳大利亚的土壤的循环的盐结果从风的成千上万的年忍受海喷雾存放远内地从沿海的区域.
These are but a few of the examples.
这些是但是一些
