以6个不同种源的文冠果种子和1～2年生苗为试验材料，对其场圃发芽率、物候期、1年生播种苗年生长规律等进行对比分析。结果表明：山东蒙山和陕西淳化县种源场圃发芽率、苗高和地径生长量均优于其他4个种源；内蒙古翁牛特旗、陕西淳化县、甘肃灵台县、青海循化县和新疆巩留县种源萌芽、展叶、开花、结果等物候期会相应提前；山东蒙山、内蒙古翁牛特旗和甘肃灵台县种源为“雨季速生型”，而陕西淳化县、新疆巩留县和青海循化县种源为“雨季缓生型”；不同种源苗高、地径的广义遗传力为0.898～0.966，苗高的种源方差分量为75.36％、84.11％，地经的种源方差分量则为72.86％、88.05％。山东蒙山、陕西淳化县2个种源，苗高、地径的遗传增益平均为16.53％和8.42％。
以6箇不同種源的文冠果種子和1～2年生苗為試驗材料，對其場圃髮芽率、物候期、1年生播種苗年生長規律等進行對比分析。結果錶明：山東矇山和陝西淳化縣種源場圃髮芽率、苗高和地徑生長量均優于其他4箇種源；內矇古翁牛特旂、陝西淳化縣、甘肅靈檯縣、青海循化縣和新疆鞏留縣種源萌芽、展葉、開花、結果等物候期會相應提前；山東矇山、內矇古翁牛特旂和甘肅靈檯縣種源為“雨季速生型”，而陝西淳化縣、新疆鞏留縣和青海循化縣種源為“雨季緩生型”；不同種源苗高、地徑的廣義遺傳力為0.898～0.966，苗高的種源方差分量為75.36％、84.11％，地經的種源方差分量則為72.86％、88.05％。山東矇山、陝西淳化縣2箇種源，苗高、地徑的遺傳增益平均為16.53％和8.42％。

The nursery seed germination,phenology,growth rhythm of one-year-old and two-year-old seedlings of 6 provenances of Xanthoceras sorbifolia were comparatively studied.The results showed that the nursery seed ger-mination,height and basal diameter of the one-year-old seedlings of provenances of Mengshan in Shandong and Wengniute County in Inner Mongolia were superior to those of the other four species.Owing to the better water and heat conditions,the sprouting stage,leaf expansion stage,flowering stage and fruiting stage of the two-year-old seedlings from provenances of Wengniute County in Inner Mongolia,Chunhua County in Shanxi,Lingtai County in Gansu,Xunhua County in Qinghai and Kongliu County in Xinjiang advanced correspondingly.In terms of growth rhythm,the provenances of Wengniute County,Mengshan County and Lingtai County were fast-growing-type in rainy season,while that of Chunhua County,Kongliu County and Xunhua County were slow-growing-type in the rainy season.The broad-sense heritability for height and basal diameter of the 6 provenances varied from 0.898 to 0.966,and the variance components of basal diameter and seedling height of the 6 provenances varied from 75.36% to 84.11% and 72.86% to 88.05% individually.The average genetic gain for height and basal diameter of Mengshan County provenance and Chunhua County provenance was 16.53% and 8.42%,respectively.
