天然杂交种的发现对林木改良来说是相当重要的。这种杂交种是在天然条件下成活的。根据这一点,可以预断它们在集约经营条件下的生长反应。在实行人工杂交前,并可约略窥出同一亲本的人工杂交种的形态、材质、生长速度、抗病能力和与气候有关的耐性等。就这一点来说,它们的价值就更大。本文
The discovery of natural hybrids is quite important for forest improvement. This hybrid is alive under natural conditions. Based on this, one can predict their growth response under intensive operating conditions. Before artificial crossing, the morphology, material, growth rate, disease resistance and climate-related patience of artificial hybrids of the same parent can be roughly observed. In this regard, they are even more valuable. This article
