不同抗性砧木对2年生赤霞珠葡萄生长发育的影响

摘要

为了研究不同抗性砧木对赤霞珠葡萄树体生长、叶片内源物质含量以及光合特性等的影响,选择弗卡(Fercal)、5C、140R、3309M、3309C、SO4、抗砧3号(Kangzhen3)、5BB为砧木与赤霞珠葡萄进行硬枝嫁接,以赤霞珠自根苗为对照(CK),对2年生赤霞珠葡萄的新梢长度、砧木和接穗粗度、叶绿素含量等生长指标以及光合速率(Pn)、蒸腾速率(Tr)、胞间CO2浓度(Ci)、气孔导度(Gs)等光合指标进行测定.结果表明:不同抗性砧木对接穗生长影响差异较大,对2年生赤霞珠葡萄生长量有抑制作用;抗性砧木均能显著提高接穗赤霞珠葡萄叶片的叶绿素含量;砧穗组合CS/3309C植株的新梢长度(160 cm)、砧木粗度(13.98 mm)、接穗粗度(13.18 mm)较高;CS/Kangzhen3植株叶片叶面积(188.83 cm2)和叶绿素含量(2.68 mg/g)较高;不同组合中,CK、CS/Fercal、CS/140R、CS/Kangzhen3在光合特性方面表现较好.抗性砧木对赤霞珠葡萄生长的各项指标产生不同程度的影响,在不同砧穗组合间以CS/3309C、CS/Fercal、CS/Kangzhen3、CS/140R表现较好,可进一步进行试验推广.%The objective of the study was to elucidate the effects of different resistant rootstocks on the growth,leaf endogenous substance content and photosynthetic characteristics of ‘ Cabernet Sauvignon’ at early period.Fercal,5C,140R,3309M,3309C,SO4,Kangzhen3,5BB were grafted with scions of Cabernet Sauvignon grapes,biennial self-rooted ‘ Cabernet Sauvignon’ plants were used as the control (CK).The effects of shoot length,rootstock diameter,scion diameter,chlorophyll content and other growth indicators and photosynthetic characteristics (Pn,Tr,Ci,Gs) were measured.The results showed that the resistance rootstocks had inhibited on growth of biennial ‘ Cabernet Sauvignon’ grape.The effect of different rootstocks on the growth was significantly different.Resistant rootstocks could significantly improve the chlorophyll content of the ‘ Cabernet Sauvignon’ grape.Shoot length (160 cm),rootstock diameter (13.98 mm) and scion diameter(13.18 mm) were significantly higher than other scion-rootstock combinations.The leaf area (188.83 cm2) and chlorophyll content(2.68 mg/g) of CS/Kangzhen3 were significantly higher than other scion-rootstock combinations.CK,CS/Fercal,CS/140R and CS/Kangzhen3 were better in photosynthetic characteristics than other scion-rootstock combinations.The results showed that the rootstocks had different effects on the growth of Cabernet Sauvignon.CS/3309C,CS/Fercal,CS/Kangzhen3 and CS/140R had a good effect on the growth of Cabernet Sauvignon grape.
