“…However, testing the adaptive potential of early sowing late-maturing cultivars in regions I-II will be the priority in future work. In contrast, our study recommended late-maturing cultivars in regions III-VI to obtain a longer growing period (table S8), which is consistent with the results of previous studies (Liu et al 2013, Bu et al 2015, Huang et al 2018.…”

“…We find that late sowing dates in regions I-II, middle sowing dates in region IV and early sowing dates in regions III and V-VI can have beneficial impacts on maize yield increases because of increased precipitation during longer growing periods (table S7). In contrast, previous studies recommend early sowing dates in regions I-II (Liu et al 2013, Bu et al 2015, Huang et al 2018. This difference is caused by the interaction between the sowing date and cultivar choice.…”

“…The adaptation potential based on our results provides different opportunities and challenges for maize production over maize growing regions. For example, in regions I-III, climate warming lengthens the growing season making it possible to plant maize cultivars with longer growing periods (Liu et al 2013, Huang et al 2018. For region IV, the high yield of maize is still limited by low growing-season precipitation, although climate change with adaptation would increase maize yields.…”

“…However, the mean annual air temperature in China has increased by 1.2°C since the 1960s (Piao et al 2010, Yu et al 2018, which becomes a major obstacle to safeguard the supply of maize due to its negative impacts on maize production (Lobell et al 2011, Wang et al 2014, Li et al 2016, Liang et al 2018. Although the impacts of climate change on maize yields depend on local climate conditions, climate warming has decreased maize yields in most maize planting regions of China mainly by shortening the maize growth period (Mo et al 2016, Huang et al 2018.…”

“…Many studies have investigated the impacts of various climate change adaptation options on maize yield and found adjusting sowing date and selecting suitable cultivars were two cost-effective adaptation options , Tachie-Obeng et al 2013, Abbas et al 2017. In general, planting maize cultivars with longer growth periods could compensate for the negative impact of rising temperatures on maize yield (Wang et al 2014, Bu et al 2015, Huang et al 2018. Earlier maize sowing was recommended for adapting to climate change in most maize planting regions in China Zhang 2010, Liu et al 2013).…”

Climate change, with increased temperatures and varied rainfall, poses a great challenge to food security around the world. Appropriately assessing the impacts of climate change on crop productivity and understanding the adaptation potential of agriculture to climate change are urgently needed to help develop effective strategies for future agriculture and to maintain food security. In this study, we studied future maize yield changes under 1.5°C (2018-2037) and 2°C (2044-2063) warming scenarios and investigated the adaptation potential across China's Maize Belt by optimizing the sowing date and cultivar using the APSIM-Maize model. In comparison to the baseline scenario, under the 1.5°C and 2°C warming scenarios, we found that without adaptation, maize yields would increase in the relatively cool regions with a single-cropping system but decrease in other regions. However, in comparison with the baseline scenario, under the 1.5°C and 2°C warming scenarios with adaptation, maize yields would increase by 11.1%-53.9% across the study area. Across the maize belt, compared with the baseline scenario, under warming of 1.5°C, the potential sowing window would increase by 2-17 d, and under warming of 2°C, this sowing window would increase by 4-26 d. The optimal sowing window would also be significantly extended in the regions with single-cropping systems by an average of 10 d under the 1.5°C warming scenario and 12 d under the 2°C warming scenario. Latematuring cultivar achieved higher yield than early-middle maturing cultivars in all regions except the north part of Northeast China. Adjusting the sowing date by increasing growth-period precipitation contributed more (44.5%-96.7%) to yield improvements than shifting cultivars (0%-50.8%) and climate change (−53.1% to 23.0%) across all maize planting regions except in the wet southwestern parts of the maize belt. The differences among the maize planting regions in terms of high adaptation potential provide invaluable information for policymakers and stakeholders of maize production to set out optimized agricultural strategies to safeguard the supply of maize.

Early freezes in the spring are becoming increasingly common. To protect farmers from low temperatures (LT), crops need improved LT tolerance. The hypothesis of this paper is that maize (Zea mays L.) hybrids released in the 2000s had higher LT tolerances than those released in the 1970s. In the study, eight popular maize released between 1970 and 2010 were subjected to LT in four different trials. Germination time, growth uniformity, recovery ability from LT stress, and leaf productivity at seedling stage are important indicators in evaluating LT tolerance of maize. Hybrids released in the 1970s had a higher gibberellin A3 (GA3) content in seeds, which resulted in faster germination in LT (P = .02). In contrast, plant growth uniformity of the 2000s hybrids were higher than that of the 1970s hybrids in LT (P = .00 at emergence). Upon being returned to warm temperatures, the 2000s hybrids recovered more rapidly than old ones mainly because of the larger root systems, higher GA3, and indole‐3‐acetic acid (IAA) content in seedlings. In addition, the 2000s hybrids had a higher chlorophyll content, Fv/Fm, soluble sugar and starch content, and antioxidant enzyme activity in seedlings than old hybrids in LT, which can also contribute to a fast recovery from LT stress. Based on the growth uniformity and recovery ability from LT stress, new hybrids showed a higher LT tolerance than old hybrids during early growth stage. This study showed the genetic tolerance in LT may exist in hybrids that were released 50 yr ago, and that exporting differences between hybrids possible mechanism of temperature tolerance can be identified.

The increasingly revealed effects of climate change threaten tropical fruit production. Considerable production loss and unstable yield has been observed in China and other regions with similar climate condition. Accordingly, this paper aims to explore the impacts of environmental conditions, phenological periods, and production endowments on a tropical fruit yield, namely lychee, by using the extended Cobb–Douglas model. Lychee (Litchi chinensis Sonn.) is chosen as the focus of this study given it is one of the most climate‐sensitive tropical fruits which have important contributions to the health, economy, and culture in South China. The growth‐span was divided into four phenological periods, namely: exposure period, heading period, flowering period and maturing period. A two‐way fixed effect model is employed for county‐level mixed‐frequency panel data. This data comprises lychee yield, environmental conditions (mean temperature, minimum temperature, and precipitation), production endowments (labor input, capital input, and technical input), and phenological periods in 39 main producing counties in China from 2011 to 2019. The key conclusions of interest are (1) higher minimum temperature results in larger lychee yield, (2) higher minimum temperature in the earlier phenological period has larger positive impact on lychee yield, and (3) higher growth in technical input causes lower lychee yield, and an explanation is provided. Heterogeneity analysis further implies various effects of the minimum temperature influencing lychee yield. The minimum temperature has a significant positive effect on lychee yield in non‐coastal and non‐western counties, especially in earlier phenological periods.
