FACTORS AFFECTING THE GERMINATION AND ESTABLISHMENT OF MONOGERM SUGAR BEET


3.2.3     The Emergence Test

 

The results from the emergence test are presented in Table 5.  The emergence percentages, from compost, of all the seed lots, were all lower than the standard germination test data recorded in Experiment 1.  This reduction was most evident in seed lots 2 - 5 where the magnitude of the reduction was 20-42%.

The majority of the seedlings emerged before the 16 day count with only small numbers emerging in the final 11 day period.  However, with Lots 2 and 4 a further increase of 10-11% was recorded indicating a higher proportion of late germinations in these Lots.  After 16 days, Lot 1 produced significantly more seedlings than all other Lots.  Lots 4 and 5 produced the lowest emergence percentages and were both significantly lower than Lot 3.  The values for Lot 2 were intermediate between Lots 4 and 5, and Lot 3.  The relative emergence values for the seed lots after 27 days were similar to those after 16 days.

Average seedling dry weights were highest for Lot 1 and those from Lot 5 were lowest, being approximately half the weight of Lot 1.  The weights from Lots 2, 3 and 4 were all similar and intermediate between Lots 1 and 5.  The total seedling dry weights per tray after 16 days reflected differences between seed lots in seedling numbers and average dry weights.
