“…Chilling injury is still one of the major climate stresses for rice production in Northeast China (Liu et al, 2013;Sun & Huang, 2011;Tao et al, 2013;Wang et al, 2019). Earlier studies mainly focussed on the chilling event itself, showing that chilling events during booting and flowering have occurred more frequently since 1990 (Tao et al, 2013).…”

Despite global warming, chilling injury during the reproductive stage is still a severe climate stress in temperate rice production systems. Much work has been done on stress avoidance by altering sowing dates and cultivar maturation, but stress tolerance has received less attention. The lack of data to inform existing genetic differences in chilling tolerance impedes model-based investigations exploring this adaptation.Here, from multiple data sources, we composited control experiments of 25 major rice cultivars in Northeast China, which allows determining the genetic differences in chilling tolerance. The results suggest that newer released rice cultivars tend to resist stronger chilling than older cultivars, and there is a coexistence between highyielding and more chilling tolerance. By projecting the above statistical relationship to regional yield, our analysis indicates that the lower chilling sensitivity due to such breeding progress may reduce yield fluctuation by approximately 74% in the lousy harvest year since 1960. Our results also indicate that chilling exposure at booting and flowering not only results in sterility but also may impact grain filling. Our study highlights the quantified cultivar difference in chilling tolerance based on the existing rice genotypes that can support further simulation-driven studies on the genetic adaptation of chilling stress and improve the quantitative evaluation of cultivar chilling tolerance in crop improvement.

“…The cultivars with a longer GP by shortening VGP and lengthening RGP were adopted for early rice to improve yield meanwhile leave more days for transplanting late rice earlier (Wang et al 2017a, Ye et al 2019. The cultivars with a shorter GP were adopted for late rice to escape the cold stress during heading and grain-filling stages (Zhang et al 2016b, Wang et al 2016, 2019a. Note that, the cultivars with a longer GP by lengthening both VGP and RGP were adopted for all the three rice types during 2000-2018 except single rice in zone III.…”

Climate warming has substantially shifted plant phenology, which alters the length of growing season and consequently affects plant productivity. Recent studies showed a stalled or reversed impact of climate change on vegetation phenology since 1998, as well as an asymmetric warming effect. However, how field crop phenology responded to the recent climate warming and the asymmetric warming remains unknown. In addition, the relative roles of climate change, sowing date and cultivars shifts in the spatiotemporal changes of crop phenology at different regions need to be better understood. Here, using the latest 9,393 phenological records at 249 agro-meteorological stations across China over 1981-2018, we critically investigated the spatiotemporal dynamics of rice phenology and disentangled the effects of different drivers by exploiting the physiological relationship between crop phenology and thermal accumulation. The results showed that length of growing period (GP) increased by 3.24 ± 0.15 days/decade for single rice, 1.90 ± 0.22 days/decade for early rice and 0.47 ± 0.14 days/decade for late rice. Although climate warming during rice GP did not slow down, the trends in rice GP and the correlations between GP and temperature decreased generally from 1981-1999 to 2000-2018. The weakened phenological response to climate change was mainly caused by agronomic managements, especially cultivar shifts. Climate warming shortened GP by 0.84 ± 1.80, 1.23 ± 0.77, and 1.29 ± 1.24 days/decade for single rice, early rice and late rice, respectively. However, cultivar shifts prolonged it respectively by 3.28 ± 3.68, 2.15 ± 2.38, and 2.31 ± 3.36 days/decade, totally offsetting the negative effects of climate warming. Rice responded to daytime and night-time warming differently with night-time temperature affecting GPs more. Our study provided new insights that rice phenology responded to night-time warming more than daytime warming across China however the response to climate warming weakened, and cultivar shifts outweighed climate change in affecting rice phenology.

“…Even more, almost 75% of rice production in northeast China was for commodity. In recent years, extreme temperature events have occurred frequently in rice planting areas of China (Wang et al 2019; Yuan et al 2021), and cold damage has become the main meteorological disaster facing rice production, especially in northeast China (Tao et al 2013). Low-temperature stress is one of the main limiting factors affecting stable rice production in high latitude areas (e.g.…”

Background and aims In high-latitude area, climate change has resulted in frequent chilling stress which affects rice sustainable production as well as changes carbon (C) and nitrogen (N) allocation in paddy ecosystem. However, the response characteristics of C and N allocation in paddy ecosystem to low-temperature stress during key growth stage are not fully understood. Methods A rice pot experiment of two varieties combined with 13C and 15N isotope labelling method was conducted to evaluate how low-temperature stress at heading stage affects rice yield, above- and below-ground C and N partitioning, and soil C and N changes. Results Low-temperature stress significantly reduced rice grain yield of JN809 (sensitive to low-temperature stress) and J88 (resistant to low-temperature stress) varieties 27.6% and 21.4%, respectively, Low-temperature stress was prone to increase C and N accumulation in stems and leaves of rice and soil. The low temperature tolerance variety (J88) reduced the effects of low temperature stress on rice yield and the allocation of C and N between soil and rice Conclusion Low-temperature during rice heading stage significantly hindered transportation of C assimilate and absorbed N from soil. Low temperature tolerant variety reduced the effect of low temperature chilling stress on rice yield, and C and N allocation. Present study provides a basis for rice breeding and cultivation techniques that can enhance rice resilience and adaptability to climate change, as well as optimize C and N sequestration practices in rice fields to ensure high yields and resource use efficiency.
