Climate change has prolonged periods of water deficit in sugarcane and energy cane crops. This condition induces an imbalance the carbon (C): nitrogen (N): phosphorus (P) stoichiometric homeostasis, impairing accumulated nutrients from being converted into biomass. Silicon (Si) supplementation can mitigate damage caused by plants improving C:N:P balance, increasing C, N, P use efficiencies biomass conversion, reducing climate effects on study assesses beneficial Si applied through fertigation associated with foliar spraying alleviation severe for intermediate long periods. In addition, maintenance nutritional homeostasis we assessed under those conditions were increased. Four experiments conducted during first growth cycle each species. The effect was evaluated applying only seedling formation phase grown 60 days after transplanting (intermediate period). Then, supplemented 160 (long supply decreased C contents, modified ratio, increased both species at transplanting. mitigated period, which mainly observed sugarcane. When transplanting, mitigating occurred period deficit. Therefore, is a viable alternative to provide plant. It also comes that partially reverse increase efficiency

Development and Validation of a Model Based on Vegetation Indices for the Prediction of Sugarcane Yield

AgriEngineering, Год журнала: 2023, Номер 5(2), С. 698 - 719

Currently, Brazil is the leading producer of sugarcane in world, with self-sufficiency use ethanol as a biofuel, well being one largest suppliers sugar to world. This study aimed develop predictive model for production based on data extracted from aerial imagery obtained drones or satellites, allowing precise tracking plant development field. A semiparametric approach associated inverse Gaussian distribution applied vegetation indices (VIs), such Normalized Difference Vegetation Index (NDVI) and Visible Atmospherically Resistant (VARI), was developed drone images two field experiments randomized replications four varieties. These were performed under conditions identical those by farmers. Further, validation carried out scaling up analyses Sentinel-2 several commercial fields. Very often, countries Brazil, crops occupy extensive areas. Consequently, tools capable operated remotely automatically benefits management this crop avoiding laborious time-consuming sampling promoting reduction operation costs. The results application both sources data, i.e., fields, showed suitable level overlap between predicted yield using VIs generated satellite verified measuring indicating that reliable forecasting productivity months before harvest time.

Quantitative and qualitative evaluation of novel energy cane accessions for sugar, bioenergy, 1 G, and 2 G ethanol production

Industrial Crops and Products, Год журнала: 2023, Номер 203, С. 117163 - 117163

Опубликована: Июль 18, 2023

Traditionally, the sugarcane breeding programs are focused on increasing sugar content, often at expense of fiber content and biomass yield. However, with growing interest in 2 G (cellulosic) ethanol bioenergy production, there has been a paradigm shift toward quantitative parameters. This study investigated qualitative parameters energy cane clones throughout harvest season. It hypothesizes that juice composition, maturation curve will vary, reaching point where these characteristics become more desirable for industrial processes. Three (C33, C34, C35) derived from program Agronomic Institute Campinas (IAC) were selected evaluation alongside commercial reference cultivar (IAC-942094). The results indicate possesses significant potential biofuel production. Additionally, exhibit higher agricultural yields greater production sugars per unit area than traditional sugarcane. high clones, coupled their productivity, makes them excellent sources lignocellulosic material both 1 cogeneration electric energy. Energy C34 C35, particular, demonstrate to increase supply electrical thermal by up 300% 250%, respectively, compared conventional These findings highlight promising role as sustainable alternative, contributing improved sustainability indices sectors.

A Review of the Diverse Genes and Molecules Involved in Sucrose Metabolism and Innovative Approaches to Improve Sucrose Content in Sugarcane

Agronomy, Год журнала: 2023, Номер 13(12), С. 2957 - 2957

Опубликована: Ноя. 30, 2023

Sugarcane (Saccharum spp. hybrid) is the chief source of sugar and biofuel globally prominent among cash crops. Sucrose main required product in sugarcane, many studies have been performed to understand phenomena sucrose synthesis, metabolism, accumulation sugarcane. However, none concluded that a single gene responsible for content. Instead, complex mechanism consisting several genes, such as phosphate synthase genes (SPS1, SPS2, SPS4, SPS5), (SuSy1, SuSy2, SuSy4), invertase (INV, CWIN, NIN1, CINV2), phytohormone, trehalose, transcription factor (TF), protein kinase, transporter are working spatiotemporally Currently, omics approaches like transcriptomics, proteomics, metabolomics also being used explore metabolism but integrated transcriptomic, proteomic, metabolomic less reported. The results obtained from analysis more reliable because strong expression, received form abundant mRNA, does not guarantee plentiful existence associated proteins or their particular activity target cells tissues, which discloses restraint interpretation stresses significance metabolomics. This review highlights different molecules contributing at stages explaining especially It vital knowledge sugarcane breeders, particularly with content improvement bioethanol energy production.
