Despite their ecological and economic importance, the glaring knowledge gaps in scientific understanding of the Himalayan grasslands hamper their effective scientific management and also impede global synthesis under growing environmental change. To address this gap, we established three long-term ecological monitoring grassland sites in the Kashmir Himalaya and developed a standardized monitoring protocol for these ecosystems. The data generated so far from these sites revealed significant variations in vegetation composition, structure, biomass dynamics and nutrient (carbon and nitrogen) levels. Analysis of plant functional groups (PFGs), such as grasses, forbs and legumes, indicates marked differences among and between the sites. Notably, Dachigam National Park, located at a lower elevation, exhibits higher aboveground biomass and carbon storage compared to the higher-elevation sites, indicating a greater capacity to buffer against environmental changes. Aboveground and belowground biomass showed a strong negative relationship, with higher elevation sites showing relatively more belowground biomass compared to the low elevation site. Among functional groups, grasses dominated the low elevation site, while forbs and legumes formed a major component of aboveground biomass in high elevation sites. Continued monitoring of these variables over time will be pivotal to understanding how these grasslands might respond to a changing climate.

Therefore, we aimed to identify genetic variation in seed shattering in Italian ryegrass and evaluate its potential for breeding. Seed shattering was assessed by the percentage of shattered seeds, primarily after spike stripping. No significant differences in shattering were observed among five early-maturing varieties, whereas some variation was detected among five medium-maturing varieties, although the differences were not large. Plants within an extremely-early-maturing variety, ‘Minamiaoba’ (<i>n</i> = 36), and a medium-maturing variety, ‘Tachimusha’ (<i>n</i> = 95), exhibited considerable variation in seed shattering, ranging from 10.0% to 85.0% and 0.2% to 92.5%, respectively. The tensile strength of the non-basal florets accounted for the variation observed in ‘Minamiaoba’ genotypes. The correlations between seed shattering and total seed weight per spike (retained and shattered) were weak or non-significant, suggesting that reducing seed shattering could improve seed yield. In progeny derived from pair-crossed half-sibs of the reduced seed-shattering genotype, medium to high correlations (<i>r</i> = 0.46–0.79) for seed shattering were observed among different environmental conditions. Seed shattering in six progeny-parent combinations was also evaluated. The regression coefficients ranged from 0.79 to 0.95 when mean parental values were used as the explanatory variable and progeny values as the response variable, indicating high heritability.

However, the impact of different ecological environments on phyllosphere bacterial communities and the factors influencing the survival and distribution of undesirable bacteria remain unclear. Therefore, we aimed to investigate the effects of cropland and cultivars on the abundance and diversity of phyllosphere bacteria in forage crops. Field experiments were conducted on croplands (dryland, DL; paddy field, PF) and three cultivars (forage pea, FP [<i>Lathyrus sativus</i>]; Italian ryegrass, IR [<i>Lolium multiflorum</i>]; smooth vetch, SV [<i>Vicia villosa</i>]). The results revealed 87 shared operational taxonomic units (OTUs) between the PF and DL bacterial communities, while FP, IR and SV shared 58 OTUs. <i>Pantoea</i>, <i>Plesiomonas</i> and <i>Bryobacter</i> were the three most abundant genera between the two cropland types. The relative abundances levels of <i>Rahnella1</i>, <i>Aeromonas</i>, <i>Cetobacterium</i>, <i>Flavobacterium</i> and <i>Vibrio</i> were significantly different among the three cultivars (<i>p</i> &lt; 0.05). The physico-biochemical properties and microorganism numbers in SV and FP exhibited a high degree of overlap; however, they were distinct from those of IR (95% confidence interval). Physiological properties did not directly contribute to bacterial abundance but rather explained the differences in bacterial abundance among samples, likely by indirectly shaping the phyllosphere microenvironment. In summary, compared with PF, DL indirectly influenced microbial numbers indirectly by regulating leaf physiological properties, while both exhibited similar effects on bacterial diversity. Among the different forage crops, IR suppressed phyllosphere moisture and nutrient exchange owing to its lower stomatal density, resulting in a lower bacterial relative abundance than those of FP and SV. This finding elucidates bacterial community dynamics, particularly during the initial establishment phase of crop rotation systems, providing a valuable perspective for optimizing forage crop rotation strategies.</p>","PeriodicalId":56078,"journal":{"name":"Grassland Science","volume":"71 4","pages":"164-178"},"PeriodicalIF":1.1,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/grs.70008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145228178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, we observed that rainfall and canopy height have a stronger correlation with biomass production than harvest frequencies controlled by days.
