JUVENILITY IN HYBRID TEA ROSES |
| Author: | D.P. de Vries |
| Abstract:
In Hybrid Tea roses, relations between growth and juvenile period (J.P. = number of days from seed germination to flower bud appearance) were studied for three years. Plants showing a flower bud for the first time are significantly longer than those without a bud. In comparison with plants with long J.P., plants with short J.P. have shorter shoots both at bud appearance and at first flowering, flower sooner, are significantly taller when measured on one date, and yield about three times more cut flowers in 6 months. It was shown that the J.P. depends on plant development and does not govern this process. | |
