对野生二粒小麦（Triticum dicoccoides）的自然和花园种群中的异交率（t）进行了估计。自然种群的估计 t 为 0，置信上限为 0.95，范围为 0.102 至 0.925，具体取决于种群内的遗传变异。在公共花园中种植的该物种的两个基因型类别的异交率为 0.0077 和 0.0018。两种基因型之间的异交率差异归因于物候差异以及因此不同的可用花粉库。物候位移被讨论为在主要自交和异交植物的异交率估计中可能存在的偏差。
Outcrossing rates (t) were estimated in natural and garden populations of wild emmer wheat, Triticum dicoccoides. The estimated t from the natural populations was 0 with the 0.95 upper confidence limit ranging from 0.102 to 0.925 depending on the genetic variation within the population. Outcrossing rates for two genotype classes of this species grown in a common garden were 0.0077 and 0.0018. The difference in outcrossing rates between the two genotypes is ascribed to phenological differences and hence different available pollen pools. Phenological displacement is discussed as a possible bias in the estimation of outcrossing rates in both predominantly selfing and outcrossing plants.
