Starch and protein accumulation during testa development in G. biloba seeds. (a) 20 days after pollination; ((b), (c)) starch granules accumulated in testa cells 30 days after pollination; (d) protein accumulated in testa cells 30 days after pollination; ((e), (f)) 60 days after pollination; (g) 110 days after pollination; (h) 130 days after pollination; ((i), (j)) starch granules disappeared by 150 days after pollination. Figure (j) shows an amplified region from Figure (i); I: idioblast; P: protein body; S: starch granule; W: wall. Bar = 50 μm.
