Peripheral achene final mature dry weight in experiments conducted during the summers of 1994–95, 1996–97 and 1997–98 for three cultivars of sunflower differing in oil content at maturity

	Mature achene dry weight (mg)			Mature achene oil concentration (%, d. wt basis)
Cultivar	1994–95	1996–97	1997–98	1994–95	1996–97	1997–98
‘Dakar’	164·5 ± 0·92^a	134·3 ± 1·35^b	158·5 ± 0·53^c	[33·1 ± 0·19^a]	[33·3 ± 1·06^a]	30·4 ± 0·13^b
‘11051’	84·3 ± 2·03^a	93·5 ± 1·56^b	112 ± 0·23^c	[44·9 ± 0·71^a]	[42·7 ± 0·93^a]	44 ± 0·38^a
‘Prosol 35’	70·5 ± 0·77^a	89·5 ± 0·75^b	93·4 ± 0·46^c	[44·7 ± 0·44^a]	[50·5 ± 1·43^b]	55·8 ± 0·22^c

Values of the mature achene oil concentration shown in the last three columns were determined for achenes from all positions on the capitulum in 1994–95 and 1996–97 (values in square brackets) and from achenes from the peripheral position only in 1997–98. Values are means (n = 3) ± s.e. and are derived from bilinear functions fitted to experimental data.

Within each column, values followed by different letters are significantly (P < 0·05) different.
