鲁西南地区果树需冷量的研究(2002年第6期) 摘要:2000~2001年,采用Utah加权模型,先后对鲁西南地区常见的葡萄、桃和油桃、杏品种的需冷量进行了研究。结果表明:不同树种、品种的需冷量差异显著。葡萄的需冷量最高,为1010~1840C°.u。桃和油桃最低,花芽为620~910C°.u,叶芽为500~890C°.u。杏介于二者之间,花芽和叶芽均为790~910C°.u。各树种、品种的 需冷量年际间均有差异。葡葡、杏不同品种需冷量的高低与本品种果实成熟期早晚的关系表 现为成熟期早,需冷量低;成熟期晚,需冷量高。但桃树不同品种的需冷量高低与本品种的 果实成熟期无明显相关关系,果实成熟期早,但需冷量较高的情况普遍存在。同一品种其花芽、叶芽的需冷量不一,基本趋势是花芽的需冷量高于叶芽。 |

| Abstract:
Utah weighted model was used for estimating bud chilling requirements
of cultivars in grapevine, peach, nectarine and apricot in southwest Shandong
Province during 2000~2001.Chilling requirements for buds (both leaf and
flower buds) were significantly different among different species and
cultivars: that for grape were the highest (1010~1840C°.u), for apricot
lower (flower bud: 790~910C°.u, leaf bud: 790~910C°.u), for peach
and nectarine the lowest (flower bud: 620~910C°.u,leaf bud: 500~890C°.u).
Moreover, the same cultivars needed different chilling rates significantly
between different years. For grape and apricot, there was found a relationship
between chilling requirement and fruit maturation: the earlier cultivars
needed lower rate of chilling;but it was not so for peach and nectarine:
many early cultivars required higher rate of chilling. It was also dis-covered
that flower buds needed higher chilling rate than leaf buds,the basic
tendency was true almost for the entrants. Key words: grape; peach; nectarine; apricot;chilling requirement |

猕猴桃雄性株系适配性观察(2002年第6期) 摘要:经过多年研究,选育出楚源M1、楚源M2、楚源M3、楚源M4和楚源M5总共5个雄性猕猴桃株系。其中楚源M1、M2、M3为中华猕猴桃,楚源M4和M
5为美味猕猴桃。楚源M1花期早,花期7天,是早花品种丰悦的适配雄株。楚源M2花期居中, 花期15天,是中花品种魁蜜和庐山香的适配雄株。楚源M3和M4花期较晚,花期分别为14天和
13天,是迟花品种翠玉和米良1号的适配雄株。楚源M5花期晚,花期8天,是花期更迟品种金 魁、沁香和海沃德的适配雄株。 |

危害滇中砀山酥梨花的蓟马种类初报(2002年第6期) 摘要:危害滇中砀山酥梨花的蓟马为黄蓟马(Thrips
flavus Schrank)、八节黄蓟马(Thrips flavidulus Bagnall)和黄胸蓟马(Thrips flavidulus
Bagnall)。虫花率达100%,平均每朵花有11.8头。树体高度1.5m以下虫口最多,危害最重。 文献标识码:A |

干旱胁迫对苹果叶片中甜菜碱和丙二醛及脯氨酸含量的影响(2003年第5期) 山东农业大学园艺学院 马双艳 姜远茂 彭福田 山东省龙口市农业技术推广中心 孙建义 摘要:以盆栽的富士/八棱海棠和新红星/八棱海棠为试材,探讨了不同土壤水分状况下甜菜碱含量的变化及其与抗旱性之间的关关系。结果表明:在干旱胁迫下,供试品种叶片内的甜菜碱和丙二醛含量均随着协迫程度的增加呈显著上升趋势,而脯氨酸则是先减少后随着干旱程度的加重含量明显增加。苹果叶片中的甜菜碱含量与丙二醛含量呈正相关,相关系数为0.9130~0.9853,表明甜菜碱含量也是与果树抗旱生密切相关的生理指标。
