摘要: 水曲柳是东北地区优良用材树种,其木质部纤维解剖特征是木材性能的重要体现。本研究以帽儿山实验林场水曲柳种源实验林为对象,采用树木年轮学、木材解剖学方法研究水曲柳全材和早晚材的纤维解剖特征对气候变化的响应。结果表明: 帽儿山地区水曲柳幼树有10年左右的快速生长期,水曲柳的年轮宽度、纤维细胞数量和纤维细胞总面积自2003年波动上升,2011年达到峰值,此时水曲柳年轮宽度为3749.59 μm,木纤维细胞数量为3750,木纤维细胞总面积为760388.85 μm2。水曲柳全材、早晚材纤维解剖特征间相关性整体一致,年轮宽度与纤维细胞数量和纤维细胞总面积均呈显著正相关。水曲柳早材宽度、纤维细胞数量和纤维细胞总面积主要受降水的限制,与当年3月降水呈显著负相关,与当年4月降水呈显著正相关,与当年6月温度呈负相关。晚材宽度、纤维细胞数量和纤维细胞总面积与9月最低温和降水量呈显著负相关,与9月最高温呈显著正相关。低温事件下水曲柳全材宽度、纤维细胞数量和纤维细胞总面积分别显著下降19.7%、24.2%和22.0%,低温事件后其恢复力分别为1.14、1.14和1.26。帽儿山地区的水热条件共同影响水曲柳早晚材宽度和纤维细胞的生长,低温事件会显著降低水曲柳的纤维细胞数量和纤维细胞总面积,进而影响其径向生长,但水曲柳在低温事件后具有很好的恢复能力。

Abstract: Fraxinus mandshurica is a native high-quality timber species in Northeast China. The anatomical characteristics of its wood fibers are crucial indicators of wood performance. In the progeny test forest of F. mandshurica in Maoershan Experimental Forest, we investigated the response of fiber anatomical characteristics of whole ring, early-wood, and latewood to climate change by dendrochronology and wood anatomy methods. The results showed that juvenile F. mandshurica experienced a rapid growth period of approximately 10 years. From 2003 onwards, the ring width, fiber cell number, and total fiber cell area showed fluctuating increases, reaching peak values in 2011. At 2011, the ring width was 3749.59 μm, fiber cell number was 3750, and total fiber cell area was 760388.85 μm2. There was a consistent overall correlation among the anatomical characteristics of fibers in the whole ring, earlywood, and latewood. The ring width was significantly positively correlated with both fiber cell number and total fiber cell area. The ring width, fiber cell number, and total fiber cell area of earlywood were primarily constrained by precipitation. These characteristics showed a significant negative correlation with precipitation in March, a significant positive correlation with precipitation in April, and negative correlation with temperature in June. The ring width, fiber cell number, and total fiber cell area of latewood were significantly negatively correlated with the minimum temperature and precipitation in September, and significantly positively correlated with maximum temperature in September. Under the low-temperature event, ring width, fiber cell number, and total fiber cell area decreased significantly by 19.7%, 24.2%, and 22.0%, respectively. Following the event, the resilience was 1.14, 1.14, and 1.26. Both temperature and precipitation jointly affected ring width of earlywood and latewood and fiber cell growth. The low-temperature event could significantly reduce both fiber cell number and total fiber cell area, thereby inhibiting radial growth. In response to the low-temperature event, F. mandshurica showed a significant capacity for recovery.
