种源试验、种源—子代测定、子代测定—实生种子园是林木良种选育工作中常用的方法。本文试图简要地介绍有关概念、方法及提出一些建议,供大家参考。一、种源试验种源(provenance)通常泛指种子和苗木的原产地或原始起源地(origin area),因而人们也常把种源试验(provenance trial)称为产地试验。到目前为止,对于种源的确切含意仍有不同理解,有人认为种源相当于产地,产地指某个地区,而这个地区内有若干个林分;但也有人把一个或几个相邻的林分作为一个种源。例如1911年德国在北部伦茨堡林区进行的欧洲赤松(Pinus sylvestris)种源试验中,5个种源分别来自萨
Provenance test, provenance-offspring determination, offspring determination - Seed-seed garden is a commonly used method in breeding elite trees. This article attempts to briefly introduce the concepts, methods and make some suggestions for your reference. Provenance Provenance usually refers to the origin or origin of seeds and seedlings. Therefore, provenance trials are often referred to as origin tests. So far, there is still a different understanding of the exact meaning of the provenance, with some arguing that the provenance is equivalent to a place of origin, a place of origin is a certain area, and that there are a few stands in the area; but others have one or more adjacent Stand as a provenance. For example, in Germany in the Pinus sylvestris provenance test in the northern Reichstag region in 1911, five provenances were from Sa
