Pengujian Daya Berkecambah Berdasarkan ISTA
Bogor, 2 Oktober 2020
Definisi
• Perkecambahan benih: muncul dan berkembangnya kecambah
hingga mencapai stadia dengan struktur-struktur penting yang
menunjukkan kemampuan kecambah untuk berkembang menjadi
tanaman yang tumbuh baik dalam kondisi lapang optimum
• Struktur penting kecambah: kombinasi struktur berikut yang
penting untuk perkembangan tanamanSistim perakaran: akar primer dan atau akar sekunder
Poros tunas/shoot axis: hipokotil, epikotil, mesokotil (Poaceae/
Gramineae), pucuk terminal
Kotiledon
Koleoptil (Poaceae/Gramineae)
Benih
Struktur benih - 3 komponen:
1. Kulit benih / testa: Berasal dari integumen dan lapisan lain
2. Poros embrio: akan berkembang menjadi tanaman
3. Cadangan makanan untuk perkecambahan

Also, damage to embryonic structures can be caused by alternating wet and dry events and this can lead to
seedlings of the Poaceae developing split coleoptiles
