“…Previous studies had shown that the appropriate temperature for chlorophyll biosynthesis was 30 °C (Lepeduš et al, 2017;Zhang et al, 2000). Under high temperature stress, photooxidation in plants increased the production of reactive oxygen species, or the synthesis of intermediate metabolites of chlorophyll synthesis (5-aminolevulinic acid and protoporphyrin IX) was blocked, resulting in a decrease in chlorophyll content in leaves (Chen and Kuai, 2001;Sun et al, 2006).…”

Research on the effect of long-term warming on rice in cool region is still rare. This study used the widely cultivated japonica rice Jiyang100 in Northeast China as the experiment material. We set up warming treatments at three growth stages of rice in the field: the tillering-panicle initiation stage (T1), the whole growth stage (T2) and the grain-filling stage (T3). The rice yield showed a trend of T1 > T2 > T3 > CK in both years. The positive effects of T1, T2 and T3 on the total number of spikelets per hole significantly increased the yield, with average increased by 11.5%, 9.9% and 6.5%, respectively. Each warming treatment had significant positive effect on the stay-green traits, photosynthesis, sucrose synthesis, and nitrogen metabolism of rice. The yield was significantly positively correlated with SPAD, soluble sugar content, sucrose content, SPS, NR, GS, and GOGAT activity. The physiological models constructed by SPAD and sucrose content could explain the changes of the yield (R2=0.704). The stay-green traits had significant correlation between carbon and nitrogen metabolism, and it played a pivotal role in them. Wherein, SPAD had significant positive correlation with soluble sugar content, soluble protein content, NR, GS, GOGAT and GDH activity, and significant negative correlation with AI activity. The stay-green ability had significant positive correlation with Pn, soluble sugar content and soluble protein content. The above results indicated that the coupling interaction of stay-green traits, nitrogen metabolism and carbon metabolism increased the sink capacity potential and sink storage supply capacity, which was the reason for the increase in rice yield under long-term warming in cool region.

Knowledge about current state of the trees in urban areas may be important for foresting and green planting of city landscapes and for improving environmental quality in these areas. The object of this study were to screen a range of morphometric, physiological and biochemical parameters among species of the genus spruce (Picea A. Dietr.) in urban areas of Kryvyi Rih City and to assess the ecological adaptations among species of the genus spruce (Picea A. Dietr.) along an environmental gradient in urban areas of Kryvyi Rih City. During 2017-2021, the 7 research plots in Kryvyi Rih City urban areas along an environmental gradient (low, moderate and high levels of the environmental impact) and 1 research plot in the background area (control) were established. The 30–40-year-old trees of indigenous spruce species (Norway spruce (Picea abies (L.) Karst.)) and non-native spruce species (Colorado blue spruce (Picea pungens var. ‘Glauca’)) were investigated. The morphometric characteristics of trees, vitality of trees and chlorophyll a, chlorophyll b content in needles were studied. The results showed that in background area the tree height (14.5-15.1 m and 11.7-12.5 m for Norway spruce and Colorado blue spruce), diameter at breast height (25.3-28.1 cm and 24.6-27.2 for Norway spruce and Colorado blue spruce), chlorophyll a content (0.75-1.04 mg/g of wet weight and 0.96-1.24 mg/g of wet weight for Norway spruce and Colorado blue spruce) and chlorophyll b content (0.33-0.41 mg/g of wet weight and 0.42-0.50 mg/g of wet weight for Norway spruce and Colorado blue spruce) were typical of mature 30-40-year-old spruce trees. In Kryvyi Rih City urban areas the ecological stress along an environmental gradient decreased the values of growth, vitalyty and photosynthetic activity of the trees by 15-50%. Colorado blue spruce trees (non-native species) exhibit greater ecological tolerance and ecological adaptations than Norway spruce trees (indigenous species). Colorado blue spruce is less sensitive to environmental impact and have a better ecological adaptive balance of pigment content than Norway spruce. Our results confirm that from a sustainable development of the urbane areas perspective it is necessary to using the Colorado blue spruce for greene planting.
