【摘要】 以九江市林业科学研究所从南京多彩樱花良种繁育有限公司引种的12个樱花品种为研究材料,对其在赣北地区的开花物候期和花叶性状等特征与本地山樱进行比较分析。结果表明:(1)12个引种樱花品种和本地山樱均能正常生长、开花,引进樱花品种的存活率除白妙(76.25%)、一叶樱(68.75%)和八重红彼岸(86.7%)较低外,其余都在90%以上,且红绯衣、江户彼岸、御帝吉野、阳光和染井吉野5个品种表现出很强的萌芽力和生长势;(2)2018年与2017年相比7个樱花品种的开花时间普遍提前了1～7 d,花期在3月上旬到4月中旬,在花期持续时间上,阳光、江户彼岸和白妙樱的平均花期达到了31、29、27 d,比本地山樱延长了40.9、31.8和22.7%;(3)不同樱花品种的花色、花径和花瓣数量均有一定差异,红绯衣、阳光、白妙和一叶樱的花朵较大,花径分别为5.0、5.5、5.8和4.5 cm;(4)总的来说,12个引进樱花品种中以阳光和江户彼岸适应性最好,且存活率高、花期持续时间长、花和叶相对较大,红绯衣和苔清水等9个品种的适应性次之,一叶樱的适应性最弱。更多还原

【Abstract】 In this paper,12 kinds of Cerasus species introduced from Nanjing Colorful Cerasus breeding Co.LTD were used as research materials by Jiujiang Institute of Forestry Science Research to compare their flowering phenological period and flower leaf characters in Northern Jiangxi Province with the local C.serrulata lannesiana(Carrière) Makino.The results showed that:(1) Both the introduced C.species and the local C.serrulata lannesiana(Carrière) Makino also grew and blossomed normally,and the survival rate of the six kinds of imported C.species are over 90%,except that the C.serrulata’Sirotae’(76.25%),C.serrulata ’Hisakura’(68.75%) and C.speciosa ’Yaebeni-ohshima’(86.7%) are relatively low,the C.serrulata ’Matsumae-benihigorom’,C.itosakura f.ascendens,C.yedoensis ’Mikado-yoshino’,C.’Yoko’,and C.yedoensis ’Somei-yoshino’ showed strong germination and growth potential.(2) In 2018,the flowering time of seven kinds of C.species was generally about 1 to 7 days earlier than that of 2017.The flowering period was from early March to early April.In terms of the florescence duration,the average flowering period of C.’Yoko’,C.itosakura f.ascendens,and C.serrulata ’Sirotae’reached 31,29 and 27 days,which was 40.9,31.8 and 22.7 percent longer than that of local C.serrulata lannesiana(Carrière) Makino.(3) There is a certain difference in flower color,flower diameter and number of petals among different C.species.The flowers of C.serrulata ’Matsumae-benihigorom’,C.’Yoko’,C.serrulata ’Sirotae’ and C.serrulata ’Hisakura’are larger the others,with flower diameter of 5.0,5.5,5.8 and 4.5 cm respectively.(4) On the whole,among the 12 kinds of imported C.species,the C.’Yoko’ and C.itosakura f.ascendens have the strongest adaptability,and its survival rate was high,florescence duration was long,flowers and leaves were relatively larger than the other imported C.species and local C.serrulata lannesiana(Carrière) Makino,followed by 9 kinds imported C.species includ C.serrulata ’Matsumae-benihigorom’and C.serrulata ’Kokeshimidu’,while the C.serrulata ’Hisakura’ showed the weakest performance.更多还原
