“…The shorter T in the 0 kg K 2 O ha −1 treatment for Siza 3 was not conducive to absorb enough K for satisfying growth demand, which might be a reason for the sensitivity of Siza 3 to low-K. There was no obvious difference in total K accumulation in cotton plants (P > 0.05) between Simian 3 and Siza 3 (Table 2), but the percentage of K accumulation in reproductive organs was higher in Siza 3 than that in Simian 3 (P < 0.05), indicating that more K was assigned to the reproductive organs in Siza 3 in order to meet the development of bolls (Wright, 1999), possibly because biomass of reproductive organs was higher in Siza 3 than Simian 3 (Hu et al, 2015), and higher biomass of reproductive organs needed more K to maintain growth.…”

“…Our previous work (Hu et al, 2015) has showed that K application could increase plant biomass and affect the partitioning of biomass in different organs for Simian 3 and Siza 3, but the effects of K application on K accumulation process and partitioning were lacking. In the present study, the results showed that K application changed the K accumulation pattern.…”

The activities were determined according to Hu et al (2015). 350 L reaction mixtures (50 mM of fructose-6-P for SPS or 50 mM of fructose for SuSy in sucrose synthesis, 50 mM of UDP-glucose, 10 mM of MgCl 2 and 50 mM of extraction buffer) were put into a test tube, then 200 L of enzyme extract was added in the tube.…”

“…However, the K reserves of China are scanty. With the considerable application of N and P fertilizers, soil K deficiencies have been increased across 30 provinces in China ( Hu et al, ). The deficiencies of soil K will thus limit crop growth and represent a significant threat to Chinese crop production in the future.…”

Potassium (K) is one of the major mineral elements required for normal growth of cotton. However, understanding the effect of controlled‐release K fertilizer on leaf photosynthesis and K use efficiency (KUE) of cotton is currently limited. A two‐year pot experiment was consecutively conducted in 2014 and 2015 with three kinds of K fertilizer including K2SO4, KCl, and polymer‐coated KCl (CRK), each at four application rates (0.00, 0.86, 1.73, and 2.59 g K plant−1, respectively). For each type of K fertilizer, the yield and K uptake of cotton increased but the KUE decreased with higher K fertilizer application. The release characteristics of K from CRK corresponded well to the K requirements during cotton growth. Plant‐available soil K, as well as leaf SPAD values, net photosynthetic rate (Pn), maximal photochemical efficiency (Fv/Fm), and effective quantum yield of photosystem II (ΦPSII) in CRK treatments were increased after full bloom stage compared to conventional K fertilizers under the same potassium application rate. Consequently, the CRK treatments significantly increased lint cotton yields by 8.1–32.7% and 3.7–20.8%, while the KUE increased by 15.5–54.8% and 14.5–45.4% compared to KCl and K2SO4 treatments, respectively. The results indicate that the application of CRK is intensively recommended to replace conventional potassium fertilizers for gaining greater yields and higher KUE of cotton.

“…Similar results were observed in previous study (Loka & Oosterhuis, ). Sucrose is one of the main products of photosynthesis and is the primary photosynthate transported from source to sink tissues (Hu et al., ). Compared with the control treatment, the lower maximum sucrose content in LSCB growing on FB 2–3 , FB 6–7 and FB 10–11 (Table ) under elevated temperature also suggested that high temperature stress had a restriction on the sucrose synthesis.…”

Effects of long‐term elevation of air temperature on sucrose metabolism in cotton leaves at different positions

Global warming could possibly increase the air temperature by 1.8–4.0°C in the coming decade. To forecast the effects of long‐term elevation of air temperature on sucrose synthesis in cotton leaves at different positions, field experiments with the treatments of ambient temperature (control) and elevated temperature (2–3°C) across cotton's boll forming stage were conducted in 2011 and 2012. Results showed that sucrose content in the fourth main‐stem leaves from the terminal (FMLT) during 10–17 days after treatment (DAT) and in the leaves subtending the cotton boll (LSCB) during 17–45 days post‐anthesis (DPA) was lower in the increased temperature treatment than control treatment, but starch content was higher, resulting in higher specific leaf weight (SLW). Lower sucrose content might be attributed to low ribulose‐1,5‐bisphosphate carboxylase‐oxygenase (Rubisco) and cytosolic fructose‐1,6‐bisphosphatase (cy‐FBPase) activities under elevated temperature for all tested leaves. Comparison of different fruiting branch (FB) positions, sucrose transformation rate just decreased in LSCB growing on FB2–3 and FB6–7. Compared with FB10–11, the leaves at FB2–3 and FB6–7 were more sensitive to the increased temperature, showing as that the changing amplitudes of SLW, sucrose content, starch content, initial Rubisco activity and cy‐FBPase activity were greater. Regarding different types of cotton leaves, the effects of elevated temperature on sucrose content, starch content and initial Rubisco activity in FMLT were obvious at the early stage (10–17 DAT), but were not obvious at the late stage. However, the effects were consistent in LSCB from 17 to 45 DPA. In addition, long‐term elevated temperature had smaller impacts on above indices in FMLT than LSCB. Sucrose phosphate synthase (SPS) and sucrose synthase (SuSy) activities were decreased by elevated temperature in FMLT at the early stage, but were increased in LSCB, suggesting that SPS and SuSy were the key enzymes between FMLT and LSCB in response to elevated temperature.
