Figure 5. Fluorescence in seedling of MSYY85 pelleted with T3 method under illumination of different lights.

Ck: the top row, seedlings from control seeds pelleted without rhodamine B and magnetic powder after 7 days germination (×7); two columns from left to right: under natural light and green light, respectively; A and B: seedlings from seeds pelleted with T3 (2 g seeds pelleted with 15 g bentonite and 84 g powder mixture which consisted of 79.8 g talc and 4.2 g magnetic powder. Meanwhile, a 2.0 mg/ml of rhodamine B solution was sprayed in place of water when the seed was coated with bentonite (RB and MP dual-labels)) germinated for 7 days (A, the second row) and 16 days (B, the third row), respectively (×7); a: the cotyledon of control seedling under green light excitation (546 nm) (×20); b and c: the cotyledon of T3 seedling under green light excitation (546 nm) after 7 and 16 days germination, respectively (×20).
