| 中文摘要: |
| 为探究不同烫种处理方式对柑橘种子发芽及幼苗农艺性状的影响，以晚锦橙种子为试材，利用40、50、60 ℃分别于剥皮前、后进行烫种处理，测定晚锦橙种子的发芽势、发芽率及幼苗株高、根长、鲜重、叶片数及叶宽。结果表明：单一处理中，仅剥皮处理促进柑橘种子萌发及幼苗生长的效果优于仅烫种。复合处理整体效果优于单一处理，烫种剥皮组合优于仅烫种仅剥皮。复合处理中，40、50 ℃处理可显著提高发芽率，其中剥皮＋50 ℃烫种15 min处理下，发芽势、发芽率分别达50%、94%，幼苗株高、根长、鲜重、叶片数均为所有处理中最高，较CK分别显著提升29.6%、24.9%、82.6%与20.0%，对幼苗生长的促进作用最为显著。60 ℃烫种抑制根生长。综上，剥皮＋50 ℃烫种处理对柑橘种子萌发及幼苗生长效果最优。 |
| 英文摘要: |
| To investigate the effects of hot water soaking combined with seed coat peeling on citrus seed germination and seedling growth, fresh seeds of wanjincheng orange were treated with 40, 50, and 60 ℃ hot water before or after seed coat peeling, and germination-related and seedling agronomic traits were determined. Results showed that single seed coat peeling outperformed single hot water soaking, and combined treatments were superior to single treatments, with peeling followed by soaking performing best. Peeling combined with 50 ℃ soaking for 15 min yielded the highest germination potential (50%) and germination rate (94%), and maximized seedling height, root length, fresh weight and leaf number, with 29.6%, 24.9%, 82.6% and 20.0% significant increases over CK, respectively. Soaking at 60 ℃ inhibited root growth. Thus, seed coat peeling plus 50 ℃ hot water soaking is the optimal treatment for citrus seed germination and seedling growth. |
