摘要

空气或土壤温度略微升高,超过马铃薯种植的最佳温度范围,就会影响马铃薯在世界不同地区的表现。为了评估智利南部未来气候条件的潜在影响,在两个生长季节(2021/2022年和2022/2023年)进行了一项田间试验,以考察气温(+ 3-4 °C)和土壤温度(+ 2-3 °C)的升高对一种现代马铃薯基因型和三种智利本地马铃薯基因型的生物量积累和生长动态的影响。为了在整个作物生长周期内提高温度,本研究采用了被动式加热系统(即开顶箱和聚乙烯地膜)。结果表明,由于空气和/或土壤温度升高,商业基因型 Asterix 在所有升温处理中都出现减产。相比之下,智利本地马铃薯在对抗高气温时具有相对优势,但在对抗较高土壤温度时则没有。正如预期的那样,块茎产量的变化与不同马铃薯基因型的结构和生长动态的变化相吻合。较热的土壤会强烈影响块茎的同化物分配,导致在较高温度下产量较低。

Plant Growth Adaptations of Chilean Native Potato Under Higher Soil and Air Temperature: A Field Comparative Study

Plant Growth Adaptations of Chilean Native Potato Under Higher Soil and Air Temperature: A Field Comparative Study

A slight increase in air or soil temperature above the optimal range for potato cultivation can affect its performance in different regions of the world. To assess the potential impacts of future climatic conditions in southern Chile, a field experiment was conducted in two growing seasons (2021/2022 and 2022/2023) to examine the effects of an increase in air (+ 3–4 °C) and soil (+ 2–3 °C) temperatures on biomass accumulation and growth dynamics of one modern potato genotype and three Chilean native potato genotypes. To increase the temperature during the entire crop cycle, passive heating systems (i.e. open-top chambers and polyethylene mulch) were employed in this study. Our results showed that the commercial genotype Asterix had a yield reduction across all warmer treatments due to increased air and/or soil temperature. In contrast, the Chilean native potatoes had a comparative advantage against high air temperatures but not against higher soil temperatures. As expected, tuber yield changes coincided with variations in architecture and growth dynamics, differing among the different potato genotypes. Warmer soils would strongly influence the partitioning of assimilates to tubers, resulting in lower yields at higher temperatures.
