Lindale, Texas |
Variety: Marquis Bocella Planting date: Cuttings were rooted in small pots about December 24, 1999, and transplanted to one-gallon pots about February 4, 2000 |
Vitazyme application: Vitazyme was applied at approximately a 13 oz/acre rate by itself every 21 days, beginning shortly after repotting. Thus, during the 6 weeks of the test the roses received three treatments, but only the first two were involved in the growth stimulation for this study; the last treatment was at the very end. |
Average stem length:
Control: 31.2 cm
*Significantly greater than the control at
P=0.0002.
|
|
Fertilization: A mixed fertilizer was occasionally applied to both treatments, and the potting soil contained slow-release fertilizers. |
