Frequency distributions of the number of flowers per inflorescence indicated that the number of flowers per inflorescence tended to be strongly clustered around a mode of 8 and 9 for the years 1982 and 1985 respectively; the frequencies of the more extreme numbers decreased rapidly. Frequency distributions for years 1983 and 1984 were relatively flat over a range of 6 to 14 flowers per inflorescence (Figure 4). Seed Number and Mass A single fruit from the Saskatoon has the potential to produce 10 seeds, but this potential was rarely achieved. Of the fruit examined in 1982, , and in 1984, 86% (n = 35 and 43 fruit, respectively) contained from 1 to 3 viable seeds. A further of the fruit examined contained 4 or 5 seeds, and only 0 to of the fruit examined in both years contained more than 5 seeds (Figure 5). The mean (+ standard deviation) number of seeds per fruit was + in 1982 and ± in 1984; seed to ovule ratios were therefore and respectively. Consequently, 73-80% of the 1982. 3 4 S e 7 S a 10 11 12 13 14 19 Number of flowers/Inflorescence 1983 3 4 S e 7 B S 10 11 12 13 14 IS Number of flowers/Inflorescence 1984 1985 100 >. u so c e 3 c eo a it 40 3 4 S « 7 S > 10 11 12 13 14 19 Number of flowers/Inflorescence.
