Sugarcane is a significant primitive source of sugar and energy worldwide. The progress in enhancing the content sugarcane cultivars remains limited due to an insufficient understanding specific genes related sucrose production. present investigation examined enzyme activities, levels reducing non-reducing sugars, transcript expression using RT-qPCR assess gene associated with metabolism high-sucrose clone (GXB9) comparison low-sucrose sister (B9). Sucrose phosphate synthase (SPS), phosphatase (SPP), (SuSy), cell wall invertase (CWI), soluble acid (SAI), neutral (NI) are essential enzymes involved sugarcane. activities these were comparatively quantified analyzed immature maturing internodes high- clones. results showed that higher-sucrose-accumulating had greater concentrations than low-sucrose-accumulating clone; however, higher both Hexose for SPS SPP high-sucrose-storing clone. SuSy activity was further, degree considerably mature clones Conversely, exhibited up-regulated enhanced compared suggests plays major role increased accumulation sucrose. These findings provide opportunity improve by regulating transgenic techniques.

Leaf photosynthesis is a powerful indicator for evaluating growth and tolerance to environmental stresses in tropical fruit trees; however, its measurement requires an expensive system. To examine the applicability of new, low-cost, closed system leaf photosynthetic trees, rates each two genotypes 16 species were measured simultaneously using open systems following accuracy evaluation by regression analysis with values from standard as explanatory variable. For all combinations, significant strong positive correlations obtained “Fair” accuracy. Photosynthetic tended be overestimated Significant observed species. Accuracy differed among periods, tendency toward inferior at lower rates. The was sometimes (“Poor” or “Fair”) seven species, whereas remaining showed generally higher (“Good” “Excellent”). Although “Good” three relationship between measurements varied periods. universal line adopted measurements, consequently demonstrating that rapid gas-exchange facilitated accurate (“Good”) ≈40 s/record) measurements.

Abstract Efficient vegetation planting is essential in highway construction to reduce greenhouse gas emissions and prevent ecological degradation. However, carbon sequestration has rarely been considered previous optimization models for strategies these environments. To address this gap, study focuses on selecting five predominant shrub species—Ailanthus altissima, Robinia pseudoacacia, Vitex negundo var. heterophylla, Amorpha fruticosa, Lespedeza bicolor—typical of the Linyi section Beijing-Shanghai Expressway. The quantifies rates water consumption species demonstrate their contribution climate change mitigation. Field data were collected spring, summer, autumn using LI-6800 portable photosynthetic system. NSGA-II was subsequently adopted establish an optimal model, considering constraints a area 1000 m² limit 1067.9 mm. Based recorded datasets implementation NSGA-II, optimized structure comprised Ailanthus altissima (21%), pseudoacacia (30%), heterophylla (11%), fruticosa (26%), bicolor (12%). By adopting novel solution, capacity per square kilometer increased by 541 kg, while decreased 104 This manuscript exemplifies achieving balance between economic benefits through targeted slopes. Local national authorities can use results implement similar different areas.
