ABSTRACT

Pedunculate oak (Quercus robur L.) seeds are very vulnerable with longevity amounting to only 2–3 years of storage. The study presents three mechanical treatment methods for acorns, a crucial process in seed storage. Four acorn samples were examined: untreated acorns, acorns scarified by cutting off part of the seed on the cup side using pruning shears, crushed acorns, and acorns with a hole drilled on the cup side. The study revealed that the best treatment methods were conventional scarification and drilling (the latter led to a smaller acorn weight loss as compared to the former). The proposed method of drilled may significantly facilitate seed emergence after prior evaluation of their viability.

摘要

有花梗橡木种子（Quercus robur L.）非常脆弱，寿命长达2–3年。该研究提出了橡子的三种机械处理方法，这是种子存储的关键过程。检查了四个橡子样品：未处理的橡子，通过使用修枝剪在杯侧切掉一部分种子而变得稀疏的橡子，压碎的橡子以及在杯侧钻有孔的橡子。研究表明，最好的治疗方法是常规的划痕和打孔（与前者相比，后者导致橡子的重量损失较小）。事先评估其生存能力后，建议的钻孔方法可能会大大促进种子出苗。
