Gibberellin
İkinci grup bitki hormonudur. 1950’li yıllarda karakterize edilen giberellinler 80’den fazla bileşin bulunduğu bir gruptur. Giberellinlerin esas etkisi, bitkilerin boyuna büyümesini sağlamaktır. Böylece uzun bir bitki gövdesi aktif giberellinleri, cüce bir bitki gövdesinden daha fazla ihtiva eder. Giberellinlerin sentezi ve kontrolü genetik kontrol altındadır.
Giberellinler izopren birimlerinden yapılmıştır. Giberellinler 4 izoprenoid biriminden türevlenen 20 karbonlu terpenoidlerir. GA -aldehit bütün bitkilerde ilk oluşan giberellinlerdir ve bütün giberellinlerin öncü maddesidir. GA ’nin hidroksilasyon ve oksidasyonu sonucunda diğer giberellinler oluşur.
İlk olarak giberellinler Gibberella fujikuroi ’ de bir metabolit olarak keşfedilmiştir. Bu mantarın pirinç fidelerinde aşırı gövde ve yaprak uzamasına sebep olduğu belirlenmiştir. 1930’larda Japon bilim insanları Gibberella fujikuroi fungusundan büyümeyi uyaran bir bileşiği kristal olarak elde etmeyi başardılar ve giberellin A olarak adlandırdılar. 1950’lerde Amerika ve İngiltere’de mantarlardan saflaştırılan maddeye giberillik asit adı verildi. 1958’de Mac Millan ve arkadaşları yüksek bitkilerde giberellin keşfettiler. Olgun olmayan tohumlardaki giberellin konsantrasyonu vejetatif dokulardakinden çok fazla olduğundan bu çalışmada tohumlar kullanıldı.

her ne kadar hormonların etkileri tek tek etkili oluyormuş gibi tartışılsa da bitkilerde büyüme ve gelişme pek çok sinyalin birlikteliğinin bir sonucudur. Ayrıca hormonlar bir diğerinin biyosentezini etkileyebilir. Dolayısıyla bir hormonun oluşturduğu etkilere diğeri aracılık edebilir. Oksinlerin etilen biyosentezini teşvik ettiği uzun zamandan beri bilinmektedir.Günümüzde giberellinin oksin biyosentezini , oksinin de giberellin biyosentezini teşvik ettiği iyi bilinmektedir.
