- 摘要：The purpose of this study is to scientifically evaluate the salt resistance of imported spring wheat varieties (lines) from Kazakhstan, and to offer references for the breeding of drought-resistant spring wheat varieties in Xinjiang. 116 spring wheat varieties introduced from Kazakhstan are selected as materials, 0% (deionized water control), 1%, and 2% NaCl solution are used as stress treatment to explore the differences in shoot length, coleoptile length, root length, fresh weight, dry weight, root dry weight, bud dry weight of introduced spring wheat varieties under salt stress during the bud stage, and conduct correlation analysis, principal component analysis, and cluster analysis on the comprehensive evaluation values (D-values) of salt tolerance of these indicators. The results show that different traits have different sensitivities to salt stress, with growth of coleoptiles is less affected than other characters, under treatment with 2% NaCl, none of the materials exhibits normal germination, treatment with 1% NaCl has a relatively minor effect on coleoptile growth, roots and buds are more affected than other characters. The salt-tolerance of materials can be divided into salt tolerance type, medium type, and sensitivity type through cluster analysis. ДБт-10 (CM1428) and Д12 Зритроспермнм(CM1429) have best salt tolerance, with D-values of 0.816 and 0.784. The salt tolerance coefficients of Колумбия(К-58014) (CM1352) and Лютесценс2145-7-83 (CM1374) exceeding 0.7. The materials provide a reference for the cultivation of salt-alkali tolerant varieties.关键词：spring wheat;germination period;salt tolerance;integrated evaluation368|14|0更新时间：2026-01-12
- 摘要：In this paper, 53 chickpea germplasm resources are analyzed by correlation analysis and principal component analysis. The coefficient of variation of the number of pods per plant is 37.70%, the coefficient of variation of the number of seeds per plant is 42.60%, the coefficient of variation of the grain weight per plant is 37.90%, and the coefficient of variation of the 100-grain weight is 35.70%, indicating that the performance of traits is rich, and having great breeding potential. Through correlation analysis, the relationship between various agronomic traits is obtained. Genetic information is primarily concentrated in four principal components, which have a cumulative contribution rate of 89.871%. Two pod-setting superior resources, D3 and D31, and the high hundred-grain weight resource D18 are screened out. In conclusion, the agronomic traits of the 53 chickpea germplasm resources are significantly different and have good richness, indicating that the genetic diversity of each trait is rich.关键词：Cicer arietinum L.;germplasm resources;phenotypic traits;genetic diversity316|5|0更新时间：2026-01-12
- 摘要：To explore the salt tolerance of wild Hippophae rhamnoides subsp. sinensis Rousi seeds during germination and their response to exogenous calcium under salt stress, two types of wild Hippophae rhamnoides subsp. sinensis Rousi seeds (Jiao 1 and Jiao 2) are used as experimental materials. Firstly, the seeds are subjected to NaCl salt stress treatments at five concentration levels (30, 60, 90, 120, 150 mmol/L), with distilled water treatment as the control (CK), to compare the salt tolerance of the two types of wild Hippophae rhamnoides subsp. sinensis Rousi seeds. The results show that, compared with the control group, the germination rate, germination energy, and germination index of Jiao 1 seeds are showed a significant decreasing trend with the increase of NaCl concentration (P<0.05). For Jiao 2 seeds, the germination index in the 30 and 60 mmol/L NaCl treatment groups is higher than that in the control group (P>0.05), and the germination rate is significantly higher than that in the control group (P<0.05). When the two types of wild Hippophae rhamnoides subsp. sinensis Rousi seeds are under 90 mmol/L NaCl stress, all indicators during the germination period significantly decreased compared with the control (P<0.05). In the treatment groups with NaCl concentration higher than 90 mmol/L, the germination initiation days are delayed by 1 day compared with the control group. Seeds of Jiao 1 and Jiao 2 are soaked in 0.2%, 0.3%, 0.4%, and 0.5% (w/v) CaCl2 solutions for 24 hours, with seeds soaked in distilled water for 24 hours as the control, followed by germination tests under 90 mmol/L NaCl stress. The results show that exogenous CaCl2 could alleviate the effect of salt stress on the germination of Jiao 1 and Jiao 2 seeds to varying degrees. The soaking treatment with 0.4% CaCl2 has the best alleviating effect on salt stress, with germination rate, germination energy, and germination index significantly higher than those of the control group (P<0.05), and the germination initiation days are the same as those of the control group. In conclusion, the salt tolerance of Jiao 2 seeds during germination is better than that of Jiao 1, and exogenous calcium can alleviate the salt stress during the germination period of the two types of wild Hippophae rhamnoides subsp. sinensis Rousi seeds.关键词：salt stress;seed germination;wild Hippophae rhamnoides subsp. sinensis Rousi;exogenous calcium265|4|0更新时间：2026-01-12
- 摘要：This study aims to evaluate the field efficacy of chemical treatments against the tomato leafminer, Tuta absoluta Meyrick, during the harvesting and seedling stages of tomatoes in solar greenhouses in the Ili River Valley region of Xinjiang. The ultimate goal is to identify the key control periods and effective chemical agents for managing Tuta absoluta. This study selects 13 environmentally friendly insecticides, including Brevibacillus brevis, 0.5% azadirachtin, 0.8% abamectin-azadirachtin, and broflanilide, to conduct field efficacy evaluations of 11 insecticides during the tomato harvesting stage. Two highly effective insecticides are screened out and further evaluated for their field efficacy during the autumn-late tomato seedling stage in Tuta absoluta-infested areas. In the solar greenhouses of the Ili River Valley, Xinjiang, the following insecticides can be applied after the early spring tomato harvesting stage: Brevibacillus brevis (SC), broflanilide (SC), 30% chlorantraniliprole (SC), 10% abamectin (SC), 1% emamectin benzoate (CS), and 46% flonicamid+acetamiprid (WDG). These treatments achieve a pest population reduction rate of over 50% within 3 days, demonstrating certain control efficacy. For the autumn-late tomato seedling stage, spinetoram (SC) and 10% abamectin (SC) can be used as control agents. Their control efficacies at 3, 7, and 14 days reach 99.81%, 91.17%, and 90.69% for spinetoram, and 90.97%, 90.97%, and 88.40% for abamectin. A 3 000-fold dilution of 10% abamectin (SC) provides satisfactory control effectiveness. The critical period for controlling tomato leafminer (Tuta absoluta) in solar greenhouses is during the tomato seedling stage. Spinetoram (SC) and 10% abamectin (SC) can serve as effective early-stage insecticides for prevention and control. For broader management of tomato leafminer, the following insecticides demonstrate efficacy: Brevibacillus brevis (SC), Broflanilide (SC), 30% chlorantraniliprole (SC), 10% abamectin (SC), 1% emamectin benzoate (CS), 46% flonicamid+acetamiprid (WDG). However, to mitigate resistance development, it is essential to rotate these insecticides appropriately during application.关键词：Tuta absoluta Meyrick;solar greenhouse;critical period for control;field efficacy evaluation36|1|0更新时间：2026-01-12
