[教學] 迷你毛氈苔孢芽 (Pygmy Drosera Gemmae) 的採集, 保存及培植 (1)

迷你毛氈苔原產於澳州西南部, 為毛氈苔其中一個獨特的分支,其名字正好表達其細小之植株形態, 原產地夏季炎熱乾燥而冬季寒冷潮濕, 土壤多為沙質土和泥炭土的混合
迷你毛氈苔植株直徑絕少超過3cm, 通常只有 1-2cm, 但只要栽培得宜, 無論是生長季節內密集而排列整齊的植株, 或者夏季花期盛放的花海, 迷你毛氈苔 都能成為一件賞心悅目的藝術品
迷你毛氈苔主要在夏季開花, 而每年冬天迷你毛氈苔都會從植株中心長出獨特的無性繁殖組織; 這些因不同種類而形態各異的鱗片或顆粒狀的綠色組織都稱為孢芽 ( gemmae ), 每片孢芽都具有一隻潛伏芽, 在原產地澳州西南部冬天的降雨季節, 植株中心這些成熟的孢芽就能隨雨水四散, 當孢芽被沖到潮濕合適的環境, 就能發芽茁壯成長
孢芽不同於種子, 孢芽本身就具有葉綠素, 加上濕冷的冬天正好是迷你毛氈苔的生長期, 所以孢芽發芽後成長速度很驚人, 如果環境理想, 整本上 6 個月內孢芽就能長成成株, 甚至還能趕及在夏天花季開花
播種孢芽非常方便加上成活率高, 所以每年冬天都是收集和繁殖迷你毛氈苔的最佳季節
採集和保存迷你毛氈苔孢芽
保存時可使用小型的密封袋, 比較好的做法是在密封袋內放一塊乾淨無香料的吸水紙, 廚房用的吸油紙就不錯用(圖一), 採集時先在密封袋裡面加水弄濕吸水紙 (當然是說蒸餾水或RO水勒 ~); 如果預計有不少品種需要採集, 可以多準備一些, 到需要用的時候才往密封袋內注水就好(圖二)

迷你毛氈苔的孢芽主要分為鱗片狀和顆粒狀兩種形態, 採集所用的工具各異; 鱗片狀的孢芽較易分散, 沾了水的牙簽就很好用了(圖三); 但顆粒狀的孢芽不易掉落, 用小型的尖頭鑷子採集比較有效率(圖四)

採集鱗片狀的孢芽最簡單, 先拿牙簽沾一沾水, 再往植株中心輕輕一掃, 孢芽就會黏在牙簽上, 這時可再把孢芽黏在密封袋內的吸水紙採集過程就完成了(圖五至八)

圖五
採集顆粒狀孢芽時用尖頭鑷子輕輕地夾在孢芽兩旁, 避免碰到在內側的潛伏芽 (圖九至十二), 由於排列成一圈一圈的孢芽成熟有序, 成熟的孢芽都在最外圍, 採集孢芽應從最外圍開始一直往內圈採; 顏色比較深, 顆粒比較大, 容易剝下來的都是已成熟的孢芽; 在內圈那些顏色比較淺, 比較小, 不容易剝下來的孢芽就是沒成熟的孢芽, 可以過幾天再行採集, 千萬不可硬剝~
圖九
不同種的迷你毛氈苔孢芽成熟期可以都不一樣, 整個採集期可長達幾個月, 如果同一個品種收集的數目較多, 同種亦可交替採集上月 (圖十三至十五)
圖十三/十四 為成熟的孢芽
如果孢芽沒有被採集或散落, 一直留在母株上, 大部分會變黑, 失去發芽能力死掉, 但有時候會變成這樣子 …但儘管如此, 成熟的孢芽還是儘早採集比較好 ( 圖十六)
圖十六
因為結構上不同於種子, 迷你毛氈苔的孢芽基本上只能保存一段很短的時間, 雖然保存期間不需陽光, 但因為孢芽必須保濕貯存, 有水的話孢芽就能萌芽, 長出長長半透明的主根甚至葉子, 而當孢芽長根生葉之後就定植就很困難了; 所以採集孢芽之後最好盡快栽種, 而即使要出售交換, 亦要盡早在兩到三星期內把孢芽送到栽培者手中, 才能增加成功率和減少麻煩. 早前我就試過從外國進口孢芽, 到埗時差不多都是長長的芽菜 …根都長到吸水紙裡面了 … 這應該就是賣家貯存過久所累, 這時候就得小心翼翼把根和吸水紙分開, 還要在介質打深深的洞埋根 …

顆粒狀迷你毛氈苔孢芽近攝, 上面比較厚的是孢芽的頂部, 離潛伏芽比較近, 比較窄的一端是基部, 長根就是從孢芽基部往下長, 冒芽則是往頂部長, 所以播種時可把孢芽基部插在土表以方便長根; 鱗片狀的孢芽則是比較尖的是頂部, 離潛伏芽比較近的一端是基部 (圖十七至十八)

Primulina longii 龍氏報春苣苔 ( syn. Chirita longii )
Primulina longii 龍氏報春苣苔 ( syn. Chirita longii )
Primulina longii has one of the biggest Primulina flowers. It is a relatively small Primulina and the plant to flower ration is eye catching. A well grown Primulina longii has numerous peduncles on a single plant and can carry up to 4 flowers each.
Primulina shouchengensis is another small Primulina species but it is less floriflorous relatively. Flower size is much smaller although it is slightly smaller than Primulina longii.
Flower color of Primulina longii varies from coerulea to purple and flower size can reach as many as 5.1cm across. I have a plant that is having beautiful leaf variegation and the variegation also inherited to its offsprings. There will be several Primulina longii primary hybrids flower in 2014 and I hope I can show you how they look like in the near future.

Primulina atropurpurea 紫萼報春苣苔 ( syn.Chirita atropurpurea )
Primulina atropurpurea ( syn. Chirita atropurpurea ) 紫萼報春苣苔
A special Primulina species having unique deep green shinny leaves that is so attractive in the genus Primulina. Leaf form of Primulina atropurpurea is a bit similar to Primulina subrhomboidea but peduncles seems to be shorter. Peduncles covered with dense purple hair. Flower color varies in different degree of purple. I am lucky to have a clone that is having more intense purple flowers with better shape compared with other clones.

Primulina medica 藥用報春苣苔 ( syn. Chirita medica )
Primulina medica ( Chirita medica ) 藥用報春苣苔
Primulina medica is one of the few species that are having high flower count. Its growing habit is rosette and rarely grow up to a tall plant with long stem. Primulina medica has numerous hairy leaves and can grow up to a leaf span exceeding 30cm. Each plant bears a lot of peduncles making a real nice scene in flowering season. Flowers do not last long and they are quite small compared with other Primulina species.
Hybrids of Primulina medica are rarely seen. I have made one breeding medica with eburnea. Flower count, size and color look like an eburnea and it inherited the hairy leaves and rosette habit of medica.
Might have to observe more hybrids before any advantage of using medica as parantage can be concluded
