APAKAH MAKSUD VERNALIZATION dalam CORSICA?
Vernalization
Vernalization adalah pemerolehan keupayaan tumbuhan untuk bunga pada musim bunga dengan pendedahan kepada musim sejuk yang berpanjangan musim sejuk, atau dengan bersamaan tiruan. Selepas vernalization, tumbuhan telah memperoleh keupayaan untuk berbunga, tetapi mereka mungkin memerlukan isyarat bermusim tambahan atau minggu pertumbuhan sebelum mereka benar-benar akan berbunga. Banyak tumbuh-tumbuhan yang tumbuh di iklim sederhana memerlukan vernalization dan mesti mengalami tempoh suhu musim sejuk yang rendah untuk memulakan atau mempercepatkan proses berbunga. Ini memastikan pembangunan reproduktif dan pengeluaran benih berlaku pada musim bunga dan musim panas, dan bukan pada musim gugur. Selesema yang diperlukan sering dinyatakan dalam waktu sejuk. Suhu vernalization biasa adalah antara 5 dan 10 darjah Celcius. Bagi tumbuhan yang banyak, seperti spesies pokok buah-buahan, tempoh sejuk diperlukan dahulu untuk mendorong dorman dan kemudian, selepas tempoh masa yang diperlukan, muncul semula dari keadaan awal sebelum berbunga. Banyak tahunan tahunan dan biovials monokarpik, termasuk beberapa ekotip Arabidopsis thaliana dan bijirin musim sejuk seperti gandum, mesti melalui tempoh yang berpanjangan sejuk sebelum berbunga berlaku.
Definisi vernalization dalam kamus Corsica
Takrif vernalisasi dalam kamus adalah perbuatan menundukkan benih tanpa tepu atau bercambah pada suhu yang rendah, yang penting bagi banyak persekitaran yang sederhana untuk memastikan percambahan dalam beberapa spesies dan berbunga pada orang lain.
