Ultimately we were unable to simply grow a pumpkin and leave well enough alone. Based on recent findings in the lab (Kharenko et al 2011 Biochemical J) we ended up subjecting the pumpkin to field trial drought stress tests in mid-August. Induction of ABA was anticipated to lead to stimulation of energy production and a larger pumpkin. However the drought stage lasted longer than anticipated leading to death of the vine and a permanent end to fruit growth. No amount of moisture re-application would revive the vine and we harvested in mid-September. Non-the less, the pumpkin weighed in at about 5 pounds, 6 ounces displaying unique and what we believe to be prize winning characteristics.
