【摘要】 该研究以吉林农业大学越橘园内78个品种(系)为试材,对其果实性状及产量等进行调查研究。结果表明:(1)越橘平均单果重0.49~3.73g,其中高丛越橘为1.13~2.92 g,半高丛越橘为1.01~1.97 g,矮丛越橘为0.49~1.33 g,杂交品系为0.67~3.73 g。越橘最大果重可达4.89 g。(2)果型指数为0.661~0.992,果实均呈扁球形。(3)越橘果实成熟期为6月中旬—9月下旬。其中早熟品种(系):高丛越橘品种有4个,半高丛越橘品种有4个,矮丛越橘品种有8个,杂交品系有8个;中熟品种(系):高丛越橘品种有18个,半高丛越橘品种有7个,矮丛越橘品种有2个,杂交品系有25个;晚熟品种(系):只有高丛越橘品种2个。(4)越橘单株产量为8.23~2632.00g。其中高丛越橘为171.97~2325.00g,产量高于1000.00g的品种有14个;半高丛越橘为553.93~2632.00g,产量均高于500.00g;矮丛越橘为8.23~1278.17g,产量高于500.00g的品种有6个;杂交品系为393.30~2465.03g,产量高于1000.00g的品系有25个,仅1个品系产量低于500.00g。更多还原

【Abstract】 Fruit appearance characters and yielding characters of 78 cultivars(strains) blueberry were studied in this experiment. The results showed that:(1)Average fruit fresh weight of blueberry was 0.49 ~3.73 g,and then that of highbush blueberry was 1.13~2.92 g,that of half-high highbush blueberry was 1.01~1.97 g,that of lowbush blueberry was 0.49~1.33 g,that of hybridization strains was 0.67~3.73 g. Maximum fuit fresh weight of blueberry was 4.89 g.(2)Fruit longitudinal-transverse diameter ratio was 0.661~0.992. The fruit shape was oblate spherical.(3)The fruiting season of blueberry was from Mid June to Late Sep. Early-maturing cultivars(strains) included four blueberry four half-high highbush blueberry,eight lowbush blueberry and eight hybridization strains blueberry. Medium-maturing cultivars(strains) included eighteen blueberry,seven half-high highbush blueberry,two lowbush blueberry and twenty-five hybridization strains blueberry. Late-maturing cultivars(strains) included two highbush blueberry.(4)Average yield per blueberry plant was 8.23~2 607.67 g. And that of highbush blueberry was 171.97~2 323.00 g,including fourteen cultivars yield higher than 1 000.00 g. That of half-high highbush blueberry was 553.93~2 632.00 g,including all the yields of them were higher than 500.00Xg. That of lowbush blueberry was 8.23 ~1 278.17 g,including six cultivars yield higher than 500.00 g. That of hybridization strains blueberry was 393.30 ~2 465.03 g,including twenty-five strains yield higher than 1 000.00 g and one strains yield lower than 500.00 g.更多还原
