1、植物生理學(xué)報(bào)PlantPhysiologyJournal2013，49(3)：277-284277不同授粉品種對(duì)蘋果果實(shí)生長(zhǎng)及內(nèi)源激素含量的影響徐臣善德州學(xué)院農(nóng)學(xué)系，山東德卅1253023摘要：以‘長(zhǎng)富2號(hào)’紅富士蘋果(MalusdomesticaBorkh．CV．RedFuji，‘NagafuNo．2’)為母本，‘美紅’、‘荷紅’和‘紅星’為授粉品種，進(jìn)行人工授粉，測(cè)定不同授粉處理的果實(shí)在生長(zhǎng)發(fā)育過(guò)程中果肉內(nèi)源激素含量、果實(shí)單果重和縱橫徑的動(dòng)態(tài)變化，從內(nèi)源激素的角度探討不同授粉品種對(duì)蘋果果實(shí)生長(zhǎng)發(fā)育的影響。結(jié)果表明：授粉品種

2、為‘美紅’和‘紅星’的果實(shí)單果重、縱橫徑凈增長(zhǎng)速率在花后10、14和22周出現(xiàn)高峰，授粉品種為‘荷紅’的果實(shí)在花后14和22周出現(xiàn)高峰；花后l8周至采收時(shí)(花后26周)，授粉品種為‘美紅’的果實(shí)的單果重、縱橫徑明顯大于其他授粉品種(P

3、5)，ABA含量在花后22-26周低于其他授粉品種(尸l<0．05)，ZR含量在花后26周高于其他授粉品種(尸<0．05)。綜上可知，不同的授粉品種通過(guò)影響蘋果果實(shí)的內(nèi)源激素水平調(diào)控果實(shí)的生長(zhǎng)，相比于其他授粉品種，‘美紅’更有利于提高果實(shí)單果重。關(guān)鍵詞：蘋果；果實(shí)生長(zhǎng)；內(nèi)源激素；授粉品種EffectsofDifferentPollinationVarietiesonFruitGrowthandEndogenousHormonesContentinMalusdomesticaBorkh．XUChen．ShanAgronomyDe
