“…2 to the decrease in yield and longevity of sugarcane fields. Water deficiency periods affect the crop development in sprouting, tillering, stalks lengthening stages, and thus yield because such stages present a high-water demand for the sugarcane culture [3,4]. Therefore, it is necessary to use supplemental, complementary, or salvage irrigation in São Paulo state to ensure the sugarcane production cycle.…”

In recent years, using pre-sprouted seedlings for sugarcane establishment has been developed in Brazil. Despite yielding promising results, the optimal irrigation management for this method during the Brazilian winter planting season has yet to be determined. Additionally, information regarding water demand and seedling behavior when subjected to different irrigation levels remains unclear. This study aimed to assess the response of pre-sprouted sugarcane seedlings to different irrigation levels during the winter in southeastern Brazil. Pre-sprouted sugarcane seedlings were subjected to different irrigation levels during the winter season in the region of Piracicaba, using a sprinkler irrigation system. Periodic evaluations were conducted, such as seedlings mortality rate, root size, root dry mass, number of sugarcane tillers sprouted per meter, total number of tillers, plant height, leaf area index, shoot dry mass, and total leaf chlorophyll index. The findings of this investigation indicate that a 10 mm irrigation level facilitated optimal fixation depth and achieved a 97.8% survival rate. Moreover, a correlation between seedling mortality rate and irrigation management was observed, emphasizing the critical role of irrigation in establishing and developing seedlings. Based on these findings, a 10 mm irrigation may represent the optimal irrigation strategy for pre-sprouted sugarcane seedlings in this scenario.

The amount of carbohydrates in sugarcane directly results from photosynthesis. This means that we can predict the weight of the cane, sucrose content, and sugar yield by examining the photosynthesis process. One way to measure the amount of photosynthesis is by using chlorophyll fluorescence or the OJIP test. This study aimed to determine the dominant OJIP variable that could predict cane weight, sucrose content, sugar yield, and measurement time. The study was conducted at the Asembagus Experimental Station in Situbondo Regency, East Java, Indonesia, from December 2016 to October 2017 using two-bud stem cuttings from 18 sugarcane clones and arranged them in a Randomized Block Design with three replications. Each clone in one replication was planted in five rows, each row being five meters long, and the center-to-center distance was 130 cm. OJIP variables were measured during the stalk elongation phase and the maturity phase. The results showed that sugarcane clones influenced OJIP variables other than Fv/Fm, cane weight, sucrose content, and sugar yield. The most accurate time for measuring OJIP variables was during the maturity phase. The dominant OJIP variables that could predict cane weight and sugar yield were TRo/RC, DIo/CS, ABS/RC, and PI (79.4% and 76.0%). The dominant predictors of yield were RC/CSo, RC/CSm, DIo/CS, PI, ABS/RC, and ETo/RC (92.9%). This study found that measuring OJIP variables during the maturity phase is ideal for predicting cane weight, sucrose content, and sugar yield. The OJIP test can quickly identify high-yielding sugarcane varieties.

Sorghum mosaic virus (SrMV, the genus Potyvirus of the family Potyviridae) is a causal agent of common mosaic in sugarcane and poses a threat to the global sugar industry. In this study, a total of 901 sugarcane leaf samples with mosaic symptom were collected from eight provinces in China and were detected via RT-PCR using a primer pair specific to the SrMV coat protein (CP). These leaf samples included 839 samples from modern cultivars (Saccharum spp. hybrids) and 62 samples from chewing cane (S. officinarum). Among these, 632 out of 901 (70.1%) samples were tested positive for SrMV. The incidences of SrMV infection were 72.3% and 40.3% in modern cultivars and chewing cane, respectively. Phylogenetic analysis showed that all tested SrMV isolates were clustered into three clades consisting of six phylogenetic groups based on 306 CP sequences (this study = 265 and GenBank database = 41). A total of 10 SrMV isolates from South America (the United States and Argentina) along with 106 isolates from China were clustered in group D, while the remaining 190 SrMV isolates from Asia (China and Vietnam) were dispersed in five groups. The SrMV isolates in group F were limited to Yunnan province in China, and those in group A were spread over eight provinces. A significant genetic heterogeneity was elucidated in the nucleotide sequence identities of all SrMV CPs, ranging from 69.0% to 100%. A potential recombination event was postulated among SrMV isolates based on CP sequences. All tested SrMV CPs underwent dominant negative selection. Geographical isolation (South America vs. Asia) and host types (modern cultivars vs. chewing cane) are important factors promoting the genetic differentiation of SrMV populations. Overall, this study contributes to the global understanding of the genetic evolution of SrMV and provides a valuable resource for the epidemiology and management of the mosaic in sugarcane.
