Sawing record Maihuenia patagonica .
用和這影片類似的播種法。Same method in this video.

蛭石加水 密閉播種 我把種子分兩組 一組用刀子在遠離凹入處的地方切一刀 一組不切
我似乎忘記給刀片消毒了。
Vermiculite and water sealed sawing. divide seed into two group 15 each.
Make a small cut away from hilum using hobby knife,the other group didn't.
I seem to forget to disinfect the blade.
影片中的教學是切在凹入處的,那邊是胚的位置,我怕傷到胚,所以改成在離胚遠的地方切一刀。
The vide cut near hilum, there is the location of the embryo, I am afraid to hurt the embryo, so i cut differently.
切組在12小時就開始萌芽了,不切組24小時才開始萌芽。因為被我在奇怪的地方切一刀,芽鑽出的樣子很怪。
Cut group began to sprout in 12 hours , not cut group 24 hours.
Because i cut seed in weird place, the seedling spout out in a strange style.
48小時後
切組 10顆發芽 以有子葉 5顆發霉
不切 9顆發芽
48hr later
cut 10 sprout already showing cotyledon 5 mold
no-cut 9 sprout
切會加快大概一天的發芽速度,但是最後發芽率差不多。發霉機率會極大的上升。
這可能是因為我忘記給刀片消毒。
結論:這個品種在台灣播種並不需要切,切的位置應該不影響發芽。如果ˋ要切,必須消毒。
cutting speed up sprout for about 24 hr,but final germination rate is close.BUT CUTING WILL GREATLY INCREASE THE FUNGI .
this may be the consequence of my sloppiness forget to disinfect the blade.
Conclusion: In Taiwan it is not necessary to cut the seed,
It seems the cut location did not affect the germination. If cut, disinfect is necessary .
6/20
播種的小苗都發霉了 30株最後發出了30棵 但是發霉24株,最後只有6株活下來,而且狀況都很差。
建議種子要埋土,因為小苗根很長的關係,埋土他才能用正常的姿勢發芽。種子一定要消毒才播種,雖然這次可能是種苗商種子品質的問題,但有了我的經驗,這個風險不該冒!
