Phytohormone changes in Neoporphyra haitanensis subjected to low temperature. A The phytohormone contents response to low temperatures. Thalli cultured at − 4, 4, 10 and 20 °C for 1 day (T-4D1, T4D1, T10D1 and T20D1) were collected to determine the levels of gibberellin (GA); N6-(2-isopentenyl) adenine (IP); salicylic acid (SA); brassinolide (Br); N6-(2-isopentyl) adenosine (IPA); trans-zeatin riboside (TZR); abscisic acid (ABA); indolepopionic acid (IAA) and methyl jasmonate (MeJA). **P < 0.01, compared to 20 °C group.
