摘要

在3年多的时间里,对5个桃品种在6个地点的叶片样品进行了10次不同的测量或计数,目的是测试苗圃中品种识别的可能性。叶片长度、叶片宽度、基部角、先端角和叶柄长度的判别值高于其他测量值。测量极大地帮助了视觉识别方法,然而,这些测量都不能单独区分某些叶子特征非常相似的品种,苗木中央梢中部的大叶子提供了最可靠的样本。

Leaf Measurements as a Means of Identification of Peach Varieties in Nursery Trees1
Ten different measurements or counts were made on leaf samples of five peach varieties in six locations over 3 years with the object of testing the possibility of identifying varieties in the nursery. Of the ten leaf-measurements, length of blade, width of blade, base angle, apex angle, and length of petiole, showed higher discriminative values than the other measurements under test. Measurements assisted considerably the visual method of identification However, none of these measurements alone made it possible to distinguish between certain varieties that were very similar in their leaf characteristics Large leaves from the middle portion of the central shoot of the nursery tree gave the most reliable samples.
