The Hexi Corridor, an important corridor connecting east-central China and the Tarim Basin, is the starting point of the Silk Road that links China and the Eurasian region. As a globally distributed fruit tree, the spread of peach was accomplished through historical trade routes in the Hexi Corridor and the Tarim Basin. However, knowledge of peach genetic diversity in these regions remains limited. In this study,we examined the relationships and the spread history of domesticated peaches through sequencing and genomic analysis of 161 peach accessions collected from Northwest China, including 43 from the Hexi Corridor and 104 from the Tarim Basin. The results indicate that peach landraces in the Hexi Corridor and the Tarim Basin are derivatives of peaches from the east and south of China (ESC). Notably, the genetic diversity of accessions from both the Hexi Corridor and the Tarim Basin was lower than that of ESC accessions. Reduction of diversity (ROD) and linkage disequilibrium (LD) analyses detected a genetic bottleneck in peaches from these regions. Additionally, these peaches have undergone varying degrees of selection from natural environment. Moreover, genes responsive to biotic and abiotic stresses were under selection, which could be the result of the climate change of Northwest China after the Last Glacial Maximum (LGM). Our findings provide a better understanding of the genetic basis of peach migration in Northwest China. Furthermore, this study expands the available genomic data for peaches and provides critical information for future peach breeding programs.展开更多

The results showed that there were significant differences in sugar and acids contents of peach fruits between different bagging treatments. The sugar con- tent of peach fruits was increased when bagged with single-layer inner-black outer- yellow paper bags and double-layer inner-white outer-yellow paper bags. The organ- ic acid content in peach fruits bagged with all the types of bags except the single- layer inner-black outer-yellow paper bag was increased greatly. The count and rela- tive content of aroma compounds were all decreased after bagging. Combined with the detection results of soluble sugar, organic acids and aroma compounds, the sin- gle-layer inner-black outer-yellow paper bag was suitable for bagging of Hongli Fe- icheng peach.展开更多

Untreated fruits stored under the same conditions were used as control fruits in the experiment. The browning level, activities of polyphenol oxidase （PPO）, peroxydase （POD） and superoxide dismutase （SOD）, and quality parameters （firmness, titratable acid, total soluble solids and total sugar） were analyzed. The results showed that the firmness of SNP-treated fruit at different stage of maturity were higher than that of the control fruit after storage for 30 days. However, no significant effect was found on total soluble solid content. The titratable acid content of low maturity fruit was higher in SNP-treated one than that of the control, but the titratable acid content of high maturity fruit treated by SNP was lower than that of the control on 10th and 30th day. In addition, the combination of SNP treatment and high maturity resulted in higher activities of SOD, lower activity of PPO and POD, lower browning level. Therefore, the combination of high maturity and SNP treatment might be a useful method to well maintain honey peach fruit quality during cold storage.展开更多

The results showed that the effects of chicken manure on soil fertility were poorer compared with organic fertilizers, but the former would bet-ter promote peach tree growth and improve yields. On the other hand, the peach fruits applied with chicken manures were smal in size and poor in commercial val-ue. What’s worse, disease rate reached 31.2% and the fruits could not be stored for a long term. Therefore, the compound management model combining agriculture and animal husbandry should intensify epidemic prevention to take place of organic fertilizers.展开更多

文摘Peach, an economically important model plant of the Rosaceae family, has been domesticated and cultivated in China for approximately5 000 years. The Hexi Corridor, an important corridor connecting east-central China and the Tarim Basin, is the starting point of the Silk Road that links China and the Eurasian region. As a globally distributed fruit tree, the spread of peach was accomplished through historical trade routes in the Hexi Corridor and the Tarim Basin. However, knowledge of peach genetic diversity in these regions remains limited. In this study,we examined the relationships and the spread history of domesticated peaches through sequencing and genomic analysis of 161 peach accessions collected from Northwest China, including 43 from the Hexi Corridor and 104 from the Tarim Basin. The results indicate that peach landraces in the Hexi Corridor and the Tarim Basin are derivatives of peaches from the east and south of China (ESC). Notably, the genetic diversity of accessions from both the Hexi Corridor and the Tarim Basin was lower than that of ESC accessions. Reduction of diversity (ROD) and linkage disequilibrium (LD) analyses detected a genetic bottleneck in peaches from these regions. Additionally, these peaches have undergone varying degrees of selection from natural environment. Moreover, genes responsive to biotic and abiotic stresses were under selection, which could be the result of the climate change of Northwest China after the Last Glacial Maximum (LGM). Our findings provide a better understanding of the genetic basis of peach migration in Northwest China. Furthermore, this study expands the available genomic data for peaches and provides critical information for future peach breeding programs.

文摘Referring to a large number of literatures, the effects of bagging, reflective film and greenhouse film on fruit size of peach were reviewed in this paper so as to provide basis for conducting relevant researches and producing larger fruits. The effects of different types of bags on fruit size of peach were analyzed. The weight variation of single fruit after bagged was investigated, and the relevant reasons were analyzed. In addition, the complexity of effect of greenhouse film on fruit size was also discussed. It is proposed that further comprehensive study on effect of bagging on fruit size should be carried out.

文摘The effects of exogenous growth regulating substance on the fruit weight of peach were reviewed. Paclobutrazol could increase the single fruit weight in dif- ferent degree, and cytokinins could also increase the single fruit weight. GA3 and B9 had no effect on fruit size or on reducing single fruit weight. Chlorflurenol-methy, ABT and salicylic acid had no effect on fruit size. Suggestions on the future re- search were put forward.

文摘With Hongli Feicheng Peach as the test material, the effects of bagging with 4 kinds of paper bags and 3 kinds of non-woven bags on the soluble sugar, organic acids and aroma compounds in peach fruits were investigated using headspace solid-phase microextraction （HS-SPME） combined with gas chromatogra- phy-mass spectrometry （GC-MS） and high-performance liquid chromatography （HPLC）. The results showed that there were significant differences in sugar and acids contents of peach fruits between different bagging treatments. The sugar con- tent of peach fruits was increased when bagged with single-layer inner-black outer- yellow paper bags and double-layer inner-white outer-yellow paper bags. The organ- ic acid content in peach fruits bagged with all the types of bags except the single- layer inner-black outer-yellow paper bag was increased greatly. The count and rela- tive content of aroma compounds were all decreased after bagging. Combined with the detection results of soluble sugar, organic acids and aroma compounds, the sin- gle-layer inner-black outer-yellow paper bag was suitable for bagging of Hongli Fe- icheng peach.
文摘Peeling trunk,binding insect-attracting belt,cleaning orchard and soil-covering under the crown were the control methods on overwintering generation of oriental fruit moth.However,they had not been applied widely on the production because of the lack of systematic quantitative evaluation.Aiming at this fact,the control effects of these technical measures were studied in peach with different ripening period.The results showed that peeling trunk was the best with the control effect of88.64%.The control effect of binding insect-attracting belt of grass bundle was74.13%,which was the most economical and efficient.Covering with soil layer of 3cm under the crown during the middle ten days of March could holdback the adult getting out from soil.Cleaning deadwood could clean out the overwintering larvae on the ground.

文摘In this study, peaches of cv. ＇Sui Yuan＇ with different maturities were treated with 0.05 mM sodium nitroprusside （SNP）, a nitric oxide donor, for 5 min, at 28℃, and then stored at 0-1.5℃ for 30 days. Untreated fruits stored under the same conditions were used as control fruits in the experiment. The browning level, activities of polyphenol oxidase （PPO）, peroxydase （POD） and superoxide dismutase （SOD）, and quality parameters （firmness, titratable acid, total soluble solids and total sugar） were analyzed. The results showed that the firmness of SNP-treated fruit at different stage of maturity were higher than that of the control fruit after storage for 30 days. However, no significant effect was found on total soluble solid content. The titratable acid content of low maturity fruit was higher in SNP-treated one than that of the control, but the titratable acid content of high maturity fruit treated by SNP was lower than that of the control on 10th and 30th day. In addition, the combination of SNP treatment and high maturity resulted in higher activities of SOD, lower activity of PPO and POD, lower browning level. Therefore, the combination of high maturity and SNP treatment might be a useful method to well maintain honey peach fruit quality during cold storage.

文摘The research explored the effects of compound management model on soil fertility and peach tree production, involving free-range chicken and returning chicken manure to fields. The results showed that the effects of chicken manure on soil fertility were poorer compared with organic fertilizers, but the former would bet-ter promote peach tree growth and improve yields. On the other hand, the peach fruits applied with chicken manures were smal in size and poor in commercial val-ue. What’s worse, disease rate reached 31.2% and the fruits could not be stored for a long term. Therefore, the compound management model combining agriculture and animal husbandry should intensify epidemic prevention to take place of organic fertilizers.
