双臂篱架赤霞珠葡萄架式结构对光照及浆果品质的影响

Effects of double-armed trellis on light intensity and grape quality of Cabernet Sauvignon

【方法】以温室的棚架、单篱架、双篱架葡萄为试材，分别采用光学显微和电子显微镜技术观测不同架式和冠位叶片的显微结构和叶绿体的超微结构。

[ Method ] Using grapes cultivated with pergola , single and double vertical trellis systems in greenhouse , and leaf microstructure and chloroplast ultrastructure in various trellis system and position were examined by light microscopy and electron microscopy .

Pn值与叶绿素含量均达到显著或极显著正相关，尤以白膜下的双臂篱架水平整枝的相关系数最大。

And the correlation of Pn and the chlorophyll content is very significant or significant , the correlative coefficient is the maximum in the horizontal training of double hedges in white film .

温室葡萄采取棚架栽培时整体叶片的叶绿体发育正常，而篱架下部叶片因长期弱光胁迫导致叶绿体结构发生异常变化。

The leaf microstructure and chloroplast ultrastructure of grapes cultivated with pergola in greenhouse developed normally , and Its were exceptional cultivated with vertical trellis system .

栽培方式对叶幕叶片光合有效辐射截留、叶果际温度微气候产生显著影响，T架与篱架叶幕温度微气候优于棚架；

Training systems had great influence on the leaf PAR capture , leaf and fruit temperature microclimate . Canopy temperature microclimate was better in T-bar and hedgerow trellis than in pergola trellis .

篱架葡萄成熟后期酯类物质相对含量高于棚架，而酮醛类物质和萜类物质相对含量低于棚架。

The relative content of esters in grapes with vertical trellis system was higher than that of pergola system during later maturation , while the relative content of ketones , aldehydes and terpenes lower .

葡萄棚架叶片和篱架上部叶片的叶绿体数、基粒数、基粒片层数明显高于篱架下部的叶片。

The number of chloroplast and basal granule s and basal granule layers of leaf of grape in greenhouse were higher in pergola and onto layer in vertical trellis system than under layer in vertical trellis system .
