This study explores the demand for low temperature accumulation during the germination process of apricot trees and analyzes the impact of warm winter phenomena caused by global warming on apricot yield. In this study, using the high-quality apricot variety ‘Haitanghong’ and its bud variant ‘Zaoyan’ from southern China as experimental materials, through transcriptomic analysis of 550 hours of treatment at 4℃, 3124 differentially expressed genes (DEGs) were identified, and many were associated with plant hormones and protein dephosphorylation. By observing the branch color of the two varieties under low-temperature treatments, we found that the cultivar with the lower chilling requirement was more tolerant to cold. These results suggest that compared to ‘Haitanghong’, ‘Zaoyan’ has a lower low-temperature requirement, and the difference in chilling requirements between the two varieties may be related to plant hormones and post-transcriptional modification. And the reason for these differences of alternative splicing may be associated with the varied chilling requirement in the two cultivars. These results can provide a reference for mitigating the decrease of apricot yield under climate warming.

The aim is to explore the effects of different formula fertilizations on the growth, quality and yield of tomato cultivated in facility substrate, aiming to screen out high-yield, high-quality and high-efficiency fertilization schemes.

With the continuous improvement in rice cultivation techniques, China has maintained a high rice production level of about 210 million tons over the past decade. Direct-seeding rice cultivation technology, recognized for its efficiency and simplicity, has been favored by Chinese farmers. However, controversies persist regarding direct-seeding rice compared to transplanted rice in national-scale production. Thus, this study employed meta-analysis techniques to quantify disparities in grain yield, economic benefit, rice quality, lodging characteristic, and greenhouse gas emissions between direct-seeding rice and transplanted rice. Our results indicated that direct-seeding rice significantly reduced grain yield by an average of 6.3% relative to transplanted rice, which was main due to the reduced total spikelet (-3.8%) and filled-grain percentage (-1.8%). In different planting systems in China, the yield of direct-seeding rice had significantly decreased compared to transplanted rice, and the direct-seeding rice-induced reductions in yield of single rice (-10.9%) and late rice (-13.1%) were higher than those of middle rice (-4.8%) and early rice (-4.4%). The grain yield reductions for direct-seeding rice were from 10% to 20% in Jilin, Liaoning, Xinjiang, Ningxia, Shandong, Jiangsu, and Zhejiang provinces, meanwhile Heilongjiang and Jiangxi provinces saw reductions of 5% to 10%, but it had no significant effect in other provinces. Direct-seeding rice resulted in comparable net economic return relative to transplanted rice (p> 0.05). Direct-seeding rice reduced milled rice rate (-3.1%) and gel consistency (-3.5%), improved appearance quality (chalkiness percentage and chalkiness degree, which decreased by 25.3% and 22.5%, respectively), whereas no significant effects were observed on nutrition quality and taste value. Direct-seeding rice increased lodging index at base of the first (+12.4%) and third (+10.3%) internodes, but not at the second internode, indicating an increase in risk of lodging relative to transplanted rice. In terms of greenhouse gas emissions, direct-seeding rice fields showed reductions in methane emissions (-42.8%), global warming potential (-36.2%), and greenhouse gas intensity (-41.1%) compared to transplanted rice fields, while promoting nitrous oxide emissions (+29.1%). In addition, a review was recounted on nitrogen utilization and its loss, water and energy use efficiency, and weed incidence. Finally, the recommendations for the future advancement of direct-seeding rice were proposed, main focusing on rice variety breeding, rice cultivation technique optimization, rice planting area layout, as well as policies and services with the goal of technological innovation and regionalized application of direct-seeding rice cultivation technology in China.

Based on the daily meteorological data, such as precipitation, rain days and sunshine duration during the flowering and fruiting stages (from November to April) of strawberry in greenhouse of Cixi City from 2012 to 2021, both occurrence frequency and intensity of continuous cloudy and rainy days in Northern Zhejiang Province were analyzed. Meanwhile, a comparative experiment was conducted regarding the application effects between silver-black mulch films (the upper layer adopts a silver mulch film while the lower layer adopts a black one) and black mulch film onto strawberry greenhouse. According to the findings, the probability of continuous cloudy and rainy days was 17.7% during the flowering and fruiting stages of greenhouse strawberry in Cixi City from 2012 to 2020, with their occurrence frequency of a slightly declining trend, and their linear trend coefficient was -0.005; the average intensity of continuous cloudy and rainy days was 6.3, with their occurrence intensity of an increasing trend, and their linear trend coefficient was 0.0264. The most frequent continuous cloudy and rainy days took place in November while the least took place in April. November saw the most frequent continuous cloudy and rainy days that lasted for over 7 days, followed by January. In the low-temperature winter and spring, both kinds of mulching modes could effectively raise and maintain the shallow soil temperature at or above 10℃; the shallow soil temperature of the silver-black-film-treated group was lower than that of the black-film-treated group, and the average temperature of the former group was 0.4℃ lower than that of the latter group; the total solar radiation of the silver-black-film-treated group was 9.1 w/m² higher in average than that of the black-film-treated group. In the early producing stage (from December to February), the average yield of strawberries treated with silver and black films was 3629.4 kg/hm² while the average yield of strawberries treated with black film was 2951.1 kg/hm², thus realizing an increase of 20%. Silver-black-film treatment exerted certain promoting effect on the SPAD value of strawberry leaf, the soluble solid and the transverse fruit diameter. Therefore, in the production, covering silver-black mulch films can improve the micro-climatic environment in the greenhouse and achieve the role of increasing production and income of strawberries.

【Objective】To develop high-yielding and FHB-resistant wheat cultivars in the Yellow and Huai River Valley Winter Wheat Zone (YHWZ), simultaneously improving of yield and resistance was conducted in this study.【Method】Using the elite parent dwarf male sterile (DMS) wheat combined with double haploid (DH) technology and molecular marker assisted selection (MAS) of Fhb1 (DMS wheat molecular breeding strategy), DH lines were developed using Sumai 3 as a donor (FHB- resistant parent) and Zhoumai 16’s DMS wheat, Zhoumai 16, Lunxuan 136 and Lunxuan 6 as recipient parents. The agronomic traits (plant height, heading date, yield, etc.) and FHB resistance were evaluated for these DH lines.【Result】A total of 51 Fhb1-DH lines characterized by facultative growth habit, semi-dwarf and white grains were selected using this strategy. The average number of infected spikelets of 51 lines were 5.7 and 7.3 at the 2020Henan and 2020Beijing sites, respectively, and average disease severities were 27.7% and 35.2%, which is not different from moderately susceptible control Huaimai 20. There was no significant difference in grain yield per hm² between the mean performance of the 51 lines and the control Zhoumai 18. DH116 (Lunxuan 20), a promising line from the 51 lines, was further evaluated for FHB resistance and agronomic traits in multiple environments. The resistance of Lunxuan 20 to FHB was significantly improved, and no significant difference was found in the number of infected spikelets or disease severity between Lunxuan 20 and moderately or highly resistant controls at four sites. Lunxuan 20 showed slightly greater grain yield per hm², and significantly higher number of spikelets per spike and thousand grain weight (P<0.05), earlier heading date and shorter plant height (P<0.05) than the control Zhoumai 18 in two environments. The grain yield per hm² of Lunxuan 20 was 4.6% and 1.7% higher than the control cultivar Bainong 207 in the two list trials of Henan Province, and 3.5% higher than Bainong 207 in the demonstration trial. Resistance of Lunxuan 20 to FHB ranged from moderate susceptibility to moderate resistance in two-year list tests using the single-floret injection and spray inoculation methods. Lunxuan 20 carries the semi-dwarfing gene Rht-D1b at the Rht-D1 locus, and the recessive alleles vrn-A1, vrn-B1 and vrn-D1 associated with the winter growth habit at the Vrn-A1, Vrn-B1 and Vrn-D1 loci. Based on the wheat 660K single nucleotide polymorphisms (SNPs), 64.7% of the SNPs were shared by Lunxuan 20 and its parents, and the direct genetic contributions of Zhoumai 16, Lunxuan 136, Lunxuan 6 and Sumai 3 to Lunxuan 20 were 69.8%, 12.6%, 6.1% and 11.5%, respectively.【Conclusion】A high-yielding and FHB-resistant wheat cultivar Lunxuan 20 was bred using the DMS wheat molecular breeding strategy.
