Sequestration of blue carbon(C)in mangrove plantations depends on site characteristics and plantation *** study evaluated the effects of plantation management on C sequestration at a C-neutral site in Xiamen,China.A field study was conducted on 10-year-old Sonneratia apetala and Kandelia obovata plantations(mono-Sa,mono-Ko)and a 15-year-old mixed plantation-.We found that mono-Ko had a significantly higher ecosystem C sequestration rate(3.32±0.62 kg C m^(-2)yr^(-1))than others when planted in the indirect shade of pioneer *** a non-native species,Sonneratia performed better(0.57±0.01 kg C m^(-2)yr^(-1))when planted with Kandelia than in monotypic *** temporary and long-term certified emission reduction(tCER and lCER)of the 12.98 ha mono-Ko was 4103.89 and 3693.50 net CO_(2)-e within 10 years,respectively.A literature review was conducted to show the compatibility of this study with other natural and plantation sites of China and Bangladesh(the native habitat for Sonneratia).The C sequestration of Sonneratia plantation sites in China is comparable with those in ***,the soil C accumulation rate for a Sonneratia monotypic plantation in Bangladesh decreased with age,yet the same did not occur in the plantations of China.

The role of wheat ears as a source of nitrogen （N） and carbon （C） in the grain filling process has barely been studied. To resolve this question, five wheat genotypes were labeled with 15N-enriched nutrient solution. N remobilization and absorption were estimated via the nitrogen isotope composition of total organic matter and Rubisco. Gas exchange analyses showed that ear photosynthesis contributed substantially to grain filling in spite of the great loss of C due to respiration. Of the total kernel N, 64.7% was derived from the N acquired between sowing and anthesis, while the remaining 35.3% was derived from the N acquired between anthesis and maturity. In addition, 1.87 times more N was remobilized to the developing kernel from the ear than from the flag leaf. The higher yielding genotypes showed an increased N remobflization to the kernel compared to the lower yielding genotypes. In addition, the higher yielding genotypes remobilized more N from the ears to the kernel than the lower yielding genotypes, while the lower yielding genotypes remobilized more N from the flag leaf to the kernel. Therefore, the ears contribute significantly toward fulfilling C and N demands during grain filling.

Interactions between above and below ground parts of plants can be considered under the(overlapping) categories of energy,material and *** energy powers photosynthesis and transpiration by above ground structures,and drives most water uptake through roots and supplies energy as organic matter to below ground parts,including diazotrophic symbionts and *** transfer occurs as water and dissolved soil-derived elements transport up the xylem,and a small fraction of water moving up the xylem with dissolved organic carbon and other solutes down the *** cytosolic nature of sieve tubes accounts for at least some of the cycling of K,Mg and P down the ***_(3)^(–) assimilation of above ground parts requires organic N transport down phloem with,in some cases,organic anions related to shoot acid-base ***-distance information transfer is related development,biotic and abiotic damage,and above and below ground resource excess and *** transfer can involve hydraulic,electrical and chemical signaling,with their varying speeds of transmission and information *** of above and below ground plant parts is an important component of the ecosystem service of storing atmospheric CO_(2) as organic C in soil,a process that has decreased since the origin of agriculture.
