3.9 Growth response to the 7 th condition

This was the condition where liquid nitrogen was applied to the soil immediately after seed sowing. Strangely all the ecotypes started growing on the 3 rd day with vigour much greater than what was to be expected. 15 N20 seeds germinated, 11 N933 seeds germinated and 9 N1601 seeds germinated. Compared to nearly all of the other conditions the application of liquid N 2 appears to have had a beneficial effect to the rate of germination of the seed, where for example under condition 6 (repeat) 11 less seeds had germinated by the 3 rd day. By the 6 th day the N933 strain had started developing true leaves where 2 of the seeds started exhibiting B characteristics. Indeed the N933 strain started developing true leaves earlier than any of the other conditions by at least 1 day.

The N20 strain didn't appear to have been affected by this condition statistically with a p value of 0.49. Again however the N1601 strain appeared to benefit from this different condition. The t-test for this condition returned a p value of 0.04 and a relatively low (but not low enough) p value was also obtained for its development into true leaves.
