碰柑

Seedless or few seed trait is one of the goals of Ponkan breeding. 通過組培方法從374粒椪柑種子培養(yǎng)中獲得449株小苗。

Results indicated that exocortis existed in all sweet orange but not in Ponkan orchards. 以酸桔為砧木之甜橙樹雖然有鱗砧病存在，但外觀仍頗健全；

Liucheng variety had the most melanose susceptibility compared with Ponkan and Tankan. 在關(guān)西調(diào)查不同種類柑桔之發(fā)病，已柳橙較為嚴(yán)重，椪柑、桶柑次之。

Besides, Ponkan, and Wentan Pummelo showed economic efficient in organic fertilizers application, but Tankan and Liucheng appeared ineffective. 其中，椪柑與文旦有機(jī)施肥經(jīng)濟(jì)與財(cái)務(wù)效果較佳，但桶柑與柳橙則較差。

The physiological differences among vesicle collapse fruit and granulation fruit and normal fruit of Ponkan mandarin (Citrus reticulata Blanco) were measured in this study. 摘要分析了椪柑萎縮型枯水與粒化型枯水以及正常果的生理差異。
