無核大金絲棗 v.s. 七月早脆王 Seedless Silk Thread v.s. Early Crisp King

 無核大金絲棗（以下、「無核」）と七月早脆王（以下、「七月」）の比較 

Comparison between Seedless Gold Thread Jujube ('Seedless') and Early Crisp King Jujube (Early)

１）　樹姿：左が無核、右が七月

　　　評価：苗の成長は両方とも速かったが、七月のほうがより旺盛

           Growth habit: Seedless (left) and Early (right)

           Review: They both grew rapidly, but Early was more vigorous.

２）葉の形状：左が無核、右が七月

　　　評価：葉は酷似

         Leaves:  Seedless (left) and Early (right)

         Review: They look almost identical

３）実の形状：左の無核を小枝ごと採って、右の七月の横に持って行く

         Take the limb off from Seedless (left), and place it next to that of Early (right)

　　

４）実の形状の評価：ほぼ同じ

　　　ただし、枝とカメラの位置関係で実のサイズの相対比較に影響が出るので、

        Shapes of fruits:  They are almost identical.

        Early on the left and Seedless on the right, in each of the picture.  

        However, size comparison can be affected by how I hold the Seedless limb, 

        relative to the camera.

５）上の枝を採って同じ平面上で比較：左が七月、右が無核

         So, I placed both limbs on a flat surface, ensuring the same distance from the camera.

         Early on the left and Seedless on the right, as above.

　　　評価：実、葉ともに見分けがつかないほど似ている

             Review: Both the fruits and leaves look identical.

なお、七月早脆王に関する疑問点：下掲の写真の実と我が家の苗の実は、全く別物に思える。

The following photos show the fruits of Early Crisp King growing in China, with a variety name plate on the tree.  The fruits on my Early look nothing like these.
