FACTORS AFFECTING THE GERMINATION AND ESTABLISHMENT OF MONOGERM SUGAR BEET
3.1.4 The effect of water-soluble seed extracts on cress seed germination
1. 30 g of seeds from Lots 1, 2 & 5 were pulverised in a hand mill.
2. The milled sample obtained was mixed with 80 ml of distilled water, periodically shaken and left in sealed bottles for 2 days.
3. Five ml of liquid extract was pipetted into petri-dishes containing 3 Whatmans' grade 181 filter papers and 50 cress (Lepidium sativum) seeds. The dishes were incubated as in Experiment 1 with daily counts.
4. Stage 3 was repeated with the extract diluted to 0.5, 0.25, 0.1 and 0.01 of the original concentration. Cress seeds were counted as having germinated when radicles >1 mm were observed. The final germination percentages and M.G.T. of the cress seeds were determined. Lots 3 & 4 were not used for this determination as chemical treatments in the processing procedure may have interfered with cress germination.
