米瓦罐栽培种与野生种特征特性研究

Studies on the Characteristics of Cultivar and Wild Species of Vaccaria Segetalis (Neck.) Garcke (V. Pyramidata Medic.)

通过米瓦罐栽培种与野生种种子特性与植株特征研究 ,得出如下结论 :米瓦罐种子在较高温度下有 3～ 4个月休眠期 ,在低温下可打破休眠 ;栽培种种子休眠浅且短 ,野生种种子休眠深且长。植株生长特性表现野生种叶片长、薄 ,根短 ;栽培驯化种叶宽、厚 ,根长。经驯化的米瓦罐向有利于人工栽培的方面发展 ,产品品质有所改良。

By the studying on the characteristics of caltivar and wild species of Vaccaria segetalis (Neck.) Garcke (V. Pyramidata Medic.) We can draw the following conclusions: The seeds hare a dormancy for 3-4 months under a higher temperature, and it may break the dormancy under the low temperature. Cultivates dormancy is dormancy under the low temperature. Cultivar seeds dormancy is shallow. and short while wild species seeds dormancy is deep and long. Wild species has a long. thin leaves and its root is short. byt cultivar plant Performance is opposite to wild species performance above. Naturalized species for Vaccaria segetalis (Neck.) Garcke (V. Pyramidata Medic.) isadvantaheous to themannal cultivation, and its product qnality has the improvement.
