| 2 | Studies on the Compositional Properties of Main Miben Series Pumpkin Varieties in Southern China显示文摘Pumpkin is among the most popular agricultural products in Southern China. To determine the important analytical properties(dry matter, total soluble sugar,dissolvable polysaccharides, mineral content, electricity conductivity, soluble solid content, fruit weight, fat, protein, fiber, pectin, β-carotene and edible rate) of pumpkin in Southern China, this study investigated the physical and chemical properties and texture of raw and steamed pumpkins of 13 Miben series varieties. Miben pumpkins were frozen at-40 ℃ for 24 h, or at-4 ℃ for 24 h, or were steamed for 15 min in boiling water to investigate the effect of different treatments on the textural change, and to reveal the texture and sensory properties of the different varieties. A total of 13 pumpkin varieties of Miben series CP1578, CP2116, XM2-2,Baimi II, Guangmi I, Guangzhouluxia, Jintong, Laojinhanzaoshu, Quanguanjixiang,Newzuhe III, V pumpkin, Zaoshutianmi and Daguomiben were involved in this study.The results showed that the Miben series pumpkins had significant difference in physical properties. The editable rate of Miben series pumpkins was higher than77%. Chemical properties varied among different varieties. Textures of pumpkin flesh after different processes were different. In the sensory assessment of Miben pumpkins, the varieties with overall quality scores more than 50 were Guangmi I, Laojinhanzaoshu, V pumpkin and Daguomiben, indicating that the four varieties all had excellent properties. | Qun ZHANG Wenhua ZHOU Gaoyang LI Yonghong LIU Hanjun TANG Meijuan YU Guizhi LU Jianwen SU | 2014 | Agricultural Science & Technology2014，15，6： | 0 |
| 3 | Research activity does not affect nest predation rates of the Silver-throated Tit,a passerine bird building domed nests显示文摘Background:Research activities have often been thought to potentially influence avian nesting success by increasing nest predation rates.Although recent studies of species building open nests and cavity nests suggest that research disturbance does not generally induce nest predation,whether it is also the case in species building domednests remains unknown.In birds,domed-nest species exist in about half of the passerine families,and research disturbance to the domed nests may differ from that to the nests of other types for their different nest structures.Methods:We investigated if research activities affected nest predation rate by analyzing the relationships of the daily nest survival rate with the research activities at the egg and nestling stages of a domed-nest species,the Silverthroated Tit(Aegithalos glaucogularis).Results:Our results showed that nest daily survival rate was significantly affected by the laying date and nest age during the egg stage,and by the hatching date only during the nestling stage.By contrast,there were no significant effects of research activities,in terms of visiting nests and filming nests,on the nest survival of the Silver-throated Tit at both the egg and nestling stages.Conclusions:Our results coincide with the findings in species building other types of nests that research activities do not always have negative effects on avian nesting success. | Qian Hu Ye Wen Gaoyang Yu Jiangnan Yin Haohui Guan Lei Lv Pengcheng Wang Jiliang Xu Yong Wang Zhengwang Zhang Jianqiang Li | 2020 | Avian Research2020，11，3： | 0 |
