Nutritional quality evaluation and proteome profile of forage species of Western Himalaya Grassl. Sci. (IF 1.3) Pub Date : 2022-03-18 Rajiv Kumar, Robin Joshi, Raman Kumar, Vidyashankar Srivatsan, Satyakam, Amit Chawla, Vikram Patial, Sanjay Kumar
Naturally occurring forage species in the high-altitude pasturelands of Western Himalaya are traditionally being utilized for feeding of livestock. However, the nutritional quality evaluation and validation of their potential as feed for livestock needs to be undertaken. Here, we evaluated proximate compositions, minerals and amino acids (AAs) of five high-altitude forage species, namely, Festuca kashmiriana

Fermentation quality and protein fractions of four Pennisetum grass silages Grassl. Sci. (IF 1.3) Pub Date : 2022-03-16 Jing Tian, Chengli Shen, Jianguo Zhang
In order to make good use of Pennisetum grasses to relieve the shortage of animal feed, the nutrients, silage fermentation quality, and Cornell Net Carbohydrate and Protein System (CNCPS) protein fractions of Pennisetum spp. were evaluated in this study. Four Pennisetum cultivars of Reyan-4, Mott, Guimu-1, and MT-1 were harvested at the first cut and second cut, and they were wilted and ensiled for

Assessment of genetic diversity and population structure of the genus Vicia (Vicia L.) using simple sequence repeat markers Grassl. Sci. (IF 1.3) Pub Date : 2022-03-01 Wei-Hong Sun, Fei-Fei Wu, Lili Cong, Mei-Yan Jin, Xian-Guo Wang
The genetic diversity of the Vicia (Vicia L.) genus was analyzed using simple sequence repeat (SSR) markers. A total of 201 sampled individuals from 12 Vicia were assayed to study the genetic diversity and polymorphisms using 12 simple sequence repeat markers; 115 alleles were identified. The average observed heterozygosity (Ho) and the average expected heterozygosity (He) were 0.4283 and 0.6941, respectively

Effect of nitrogen topdressing on planting density response of grain yield in maize with different planting pattern cultivation Grassl. Sci. (IF 1.3) Pub Date : 2022-03-01 Song Liang, Taiki Yoshihira
We investigated the maize grain yield in response to nitrogen topdressing at different planting densities and planting patterns (twin row, TR; narrow row, NR; and conventional row, CR) over 3 years using early-maturing cultivars. The P8025 grain yield was higher with a nitrogen topdressing of 6 g/m2 (N6) than without a nitrogen topdressing (N0) at all planting densities in 2017, 2018, and 2019. The

Effects of precipitation changes on the stoichiometry and photosynthetic characteristics of Stipa bungeana Trin. at different growth stages in the Loess Plateau, China Grassl. Sci. (IF 1.3) Pub Date : 2022-02-21 Xu Luo, Yutao Wang, Yi Zhang, Juan Zhang, Hongbin Ma, Jianping Li
The aim of this study was to explore the response of the stoichiometric and photosynthetic characteristics of a dominant plant species in a typical grassland to changes in precipitation. Rain shelter technology was used to simulate 50%, 100%, and 150% of natural rainfall. The photosynthetic rate (Pn), intercellular CO2 concentration (Ci), transpiration rate (Tr), stomatal conductance (Gs), and ecological

Cloning and expression analysis of ZjHSP18.9 from Zoysia japonica Grassl. Sci. (IF 1.3) Pub Date : 2022-02-21 Zhi-yong Huang, Xin-bo Sun, Yao Zou
The ZjHSP18.9 gene was isolated from Zoysiagrass by homologous cloning based on publicly available transcriptome database. Sequence alignment analysis revealed that ZjHSP18.9 protein contains a classic Hsp23/ACD domain. Phylogenetic analysis and subcellular localization prediction suggested that ZjHSP18.9 belongs to cytosolic class VI subfamily. The expression profiles of ZjHSP18.9 in leaf and root
