The Yemenite citron ((ヘブライ語:אֶתּרוֹג תֵּימָנִי), ''etrog teimani'')〔In the Yemenite tradition, the word אתרוג is pronounced with a dotted ת and שוא נח.〕 is a distinct variety of citron, usually containing no juice vesicles in its fruit's segments. The bearing tree and the mature fruit's size are somewhat larger than the trees and fruit of other varieties of citron.〔(Hebrew Forum with Participation of Growers )〕〔(A Man Holds A Yemenite Citron against his Head )〕〔(【引用サイトリンク】title=yemen )〕 == Classification, genetics and purity== Despite its major differences from standard varieties of the most common original citron, the Yemenite citron was attested by a group of citrus and genetic experts to be a true variety of citron, and possesses a close genetic relation with the rest of the types. A brief documentation of this study was presented at the Global Citrus Germplasm Network.〔(【引用サイトリンク】title=The Search for the Authentic Citron (Citrus medica L.): Historic and Genetic Analysis )〕 Current research shows that grafting should not result in hybrid speciation, which can only be obtained by cross breeding. By plants this is achieved through cross pollination, which is applying the pollen of one variety or species to the style of another type of plant before anthesis, planting the seeds of this particular flower would result to a complete mix of traits. In light of this, there is no reason to question one citron variety more than another, especially while the above genetic study shows equal purity for all. In particular it shows that the Yemenite kind is highly affiliated with the Moroccan citron which is traditionally cultivated in a remote area in the absence of any other citrus species.〔The Report by professor Eliezer E. Goldschmidt, in Halichoth Sadeh תשנ"ח, is available for reading in (Otzar haChochma ). * (The etrogim of Morocco, by Rabbi Yashar Livi )〕 Since the Moroccan citron couldn't have been grafted nor bred with any different kind of citrus, the Yemenite kind, which is genetically similar to it, should be regarded as equal. Some argue that the absence of pulp of the Yemenite kind is clear evidence for its genetic purity, and that all other varieties developed a pulp due to being grafted upon lemon or sour orange rootstock.〔(Agitation for the Yemenite Citron ), (Hebrew ) * (Yemenite Forum about their Etrog ) * (Hyde Park about the Yemenite and their Etrog ) 〕 This assertion is contested by virtue of the fact that the fruits of a Yemenite tree at the Citrus Variety Collection contain no pulp despite being grafted on rootstock of Yuma Ponderosa Lemon.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yemenite citron」の詳細全文を読む スポンサード リンク
