Fatty acid (FA) composition (µg FA per coleoptile × 100) of rice coleoptiles after 5 and 8 d of anaerobic germination (primary anoxia)

Coleoptile age	C 16:0	C 16:1	C 18:0	C 18:1	C 18:2	C 18:3	Sum satur*	Sum unsatur†	DBI‡
5 d	177·0 ± 14·3	4·50·± 0·5	15·5 ± 2·5	182·0 ± 28·0	417·0 ± 46·0	31·0·± 4·5	192·5 ± 14·5	634·5 ± 54·5	1·34
8 d	172·0 ± 21·9	4·0 ± 0·7	18·0 ± 2·9	195·0 ± 13·3	429·0 ± 22·0	31·0 ± 4·3	190·0 ± 22·1	659·0 ± 26·1	1·35

Seeds were imbibed and germinated anaerobically in a special vacuum apparatus (Vartapetian and Polyakova, 1994) after evacuation of air by oil vacuum pump.

Experiments were run in triplicate, each replicate comprising 100–120 coleoptiles.

Data represent mean ± s.d. of three replicates.

* Total sum of saturated FA; ^† total sum of unsaturated FA; ^‡ double bond index: the sum of weight per cent of each acid multiplied by the number of double bonds it contains per molecule and divided by 100.
