Effect of seedling size on post-planting growth and survival of five Mexican Pinus species and their hybrids by José Alberto Ponce-Figueroa, Pablo Antúnez, José Ciro Hernández-Díaz, José Ángel Prieto-Ruíz, Artemio Carrillo-Parra, Pablito Marcelo López-Serrano, Christian Wehenkel

“…Therefore, the aim was to evaluate the influence of initial morphological parameters of 2,007 nursery seedlings of these species and their hybrids on their growth and survival 44 months after planting in the Sierra Madre Occidental, Mexico. Methods Spearman’s coefficient (rs) and the unbiased conditional pseudo coefficient of determination (R2c) between each specific predictor and each response variable and their 95% confidence interval (CI95%) were determined using Random Forest, generalized linear model, and bootstrapping. …”

Pretreatment method of forchlorfenuron residues in loquat by HPLC analysis by YANG Chunping, LI Zhaojun, NING Hong, CHEN Huabao, GONG Guoshu, YANG Jizhi, ZHANG Min

“…Therefore, residue detection of forchlorfenuron in fruits and vegetables is imperative.High-performance liquid chromatography (HPLC) analysis is a common detection method. The suitable conditions for the extraction and purification of sample play an important role prior to HPLC analysis.In this study, the extraction efficiency of forchlorfenuron residues in loquat was compared using matrix dispersive solid phase extraction and QuEChERS (quick, easy, cheap, effective, rugged, safe).The results showed that QuEChERS was a more suitable pretreatment method for the determination of forchlorfenuron residues in loquat, because it had obviously higher average recoveries than the matrix dispersive solid phase extraction. …”
