植物的营养生长和繁殖之间存在着某种拮抗作用，这似乎仍然是研究植物发育的学生中相当普遍的观点。奢侈的植被被认为不利于配子的起始或它们的结合，导致种子和果实的明显缺失，而有限的营养生长被认为是显著生殖活动的前兆。在许多情况下，这显然是正确的。然而，事实不允许人们接受这样一种观点作为一种公理化的概括，因为对许多植物的发展的仔细分析导致了一个完全相反的概念。经验和实验证据都使人几乎没有怀疑的余地：一方面，过度的植被和缺乏果实，另一方面，生长减少和大量的种子形成之间，往往存在着一种明显可识别的联系。但问题是，在这种关系中，谁是因，谁是果；因为我们目前对高等植物各部分或器官之间的定量和定性的相互关系的认识，迫使我们接受因果关系的存在。数据可能显示出增长对繁殖的影响，但也有充分的证据表明情况恰恰相反。属于一年生植物、二年生植物和多年生植物这三大类的植物提供了大量的例子，这些例子清楚地表明：(1)营养生长几乎是由发育中的种子和果实在数量上决定的；(2)它往往在确切的时间和确切的比例减少，与花的形成和种子的数量；(3)营养生长速率受发育果实的控制。这些观念虽然与当前的观点完全相反，但似乎并不过分。由于在时间上的顺序，植被通常先于繁殖，并且由于种子和果实与植物的严格营养部分相比具有更大的经济重要性，关于植被影响的证据一直在不断收集。
Introduction That a certain antagonism exists between vegetative growth and reproduction seems still to be the rather prevailing opinion among students of plant development. Luxurious vegetation is thought to be detrimental either to the initiation of gametes or to their union, resulting in a conspicuous absence of seeds and fruit, while a limited vegetative growth is considered to be the precursor of marked reproductive activities. In many instances this apparently is true. The facts, however, do not permit one to accept such a view as an axiomatic generalization, for careful analysis of the development of many plants leads to a diametrically opposite conception. Both empirical and experimental evidence leave one hardly room for doubt that only too frequently a clearly recognizable association does exist between excessive vegetation and lack of fruitfulness on one hand, and diminished growth and abundant seed formation on the other. The question is, however, which in this relationship is cause and which is effect; for our present knowledge of correlation, both quantitative and qualitative, between the various parts or organs of higher plants compels one to accept the existence of a causal relationship. Data may be marshalled showing the effects of growth on reproduction, but there is also ample proof of exactly the reverse situation. Plants belonging to all three groups-annuals, biennials and perennials-supply a large number of examples where it is clearly evident (1) that vegetative growth is almost quantitatively determined by the developing seeds and fruit; (2) that it often decreases at the exact time and in the exact proportion to the amount of flowers formed and seeds set; and (3) that the rate of vegetative growth is controlled by the developing fruit. These conceptions, though quite contrary to a current point of view, do not appear to be overdrawn. Because of the sequence in time, vegetation usually preceding reproduction, and because of the greater economic importance of seeds and fruit as compared with the strictly vegetative parts of plants, there has been a consistent gathering of proof on the effects of vegetation * At present with the College of Agriculture, University of Missouri, Columbia, Mo.
