摘要
研究表明:闽糖70/611,闽选703,F134,福引79/8,福引79/9,NCo310和Co740等7个抗病性不同的品种,受甘蔗花叶病毒感染后叶片叶肉细胞质膜,大、中、小维管束韧皮部筛管和伴胞质膜以及伴胞细胞质中ATPase活性均明显高于其健株相应部位;而维管束鞘细胞质膜ATPase活性则底于其健株相应部位。褪绿斑部位叶肉细胞叶绿体基本解体或消失;富含叶绿体的维管束鞘细胞多为淀粉粒所占据;结果表明染病后ATPase活性的变化程度似乎与品种抗病性强弱有关。
Ultrastructural localizations of ATPase activity in the infected and non-
infected leaves by sugarcane mosaic virus str.A(SCMV-A)with 7 sugarcane
varieties were compared by a routine enzyme cytochemical technique.Results
showed that ATPase activity the cytoplasmic membrane of mesophyll cells,
phloem sieve and companion cells in 3 types of bundle and cytoplasm of com-
panion cells in SCMV-A-infected leaves with 7 different resistance varieties,
i.e.Mintang 70/611,Minxian 703,F 134,Fuyin 79/8,Fuyiu 79/9,NCo 310
and Co 740,was obviously higher than that in the healthy leaves correspon-
dingly,whereas ATPase activity in the cytoplasmic membranes of bundle shea-
th in SCMV-A-infected leaves was lower than that in the healthy sugarcane
leaves.Chlorophylls in the mesophylls with chlorotic lesions were almost dege-
nerated or disappeared.Bundle sheath cells with abundant chlorophylls origi-
nally were occupied by starch particles after their infection by SCMV-A.The
change level of ATFase activity between infected and non-infected leaves
seemed to correlate to the resistability and susceptibility of sugarcane variety.
