| 摘 要： | 为了研究仔猪感染猪等孢球虫后T细胞亚群的变化规律，应用纯种猪等孢球虫孢子化卵囊人工感染9头6日龄仔猪，分别检测了感染前1d和感染后1、3、6、9、11d (DPI) 外周血中CD3+、CD4+、CD8+T细胞。结果显示，DPI 3，CD3+、CD4+T细胞增加，之后下降，但差异均不显著（p>0.05）；CD8＋T细胞在DPI 6增加，DPI 9达峰值（P<0.05）。CD4+/CD8+值在DPI 6下降，DPI 11达到最低点。表明DPI 3感染仔猪的免疫功能有所增强，而DPI 8后仔猪免疫功能受到抑制。

| Abstract: | To grasp the key technology of seed propagation of ornamental Palmae to establish an efficient system for seed breeding,comparative study of some ornamental Palmae adopted seed storage time,planting matrix,planting methods and transplanting period of seedlings on seed germination and seedling growth.The results showed that the appropriate storage time of Palm seed depend on the origin region,seed germination rate of Livistonea chinensis and Rhapis excelsa after harvesting the seeds without storage or short-term storage collected from the Singapore was significantly higher than those collected from the seeds of Fujian,and the germination rate of sand mixed with the wet storage for a period of time collected from Fujian was significantly higher than that collected from the seeds of Singapore.Palm plants suitable for the propagation matrix was mixed matrix No.2 composed the five coconut husk,the three sand and the two peat and mixed matrix No.1 composed the five coconut husk and the five sand.Planting method of palm plants of Archontophoenix alexandrae and Dypsis lutescens used to seedbed breeding or nursery tray breeding,and planting method of Phoenix dactylifera used to nursery bags breeding.But regardless of seedbed breeding and nursery tray breeding,transplanting period of seedlings for one-leaf stage more appropriate,the later of transplanting period of seedlings,the lower the survival rate of seedlings.The results of this study revealed the several technical problems of planting breeding process for ornamental Palmae,provided the technical basis for the establishment of the seedlings technical specification for ornamental Palmae |
