Rooting responses of bermudagrass cuttings to preplant treatment1
- R.E. Burns
Rapid root development is necessary for successful use of present methods of planting improved bermudagrasses (Cynodon sp.). Turf growing in flats was subjected to variations in temperature, light intensity, and day length. Sod and shredded sprigs were stored at 27 and 5 C for 7 weeks. Cuttings from both flats and stored material were collected periodically, planted in sand, and held in a growth chamber for 10 days. None of the treatments on the intact turf affected subsequent root development of cuttings. Storage temperature had no significant effect on root development of cuttings from stored sod or shredded sprigs. At either temperature the total root length of cuttings taken from sod decreased slightly as sod storage time increased. The cuttings from shredded sprigs showed greater root development than sod early in storage, but extended storage resulted in a marked reduction in the number of cuttings which produced roots. All cuttings taken after 7 weeks of storage were brown and only 25% formed roots in the 10-day period. More than half of those that failed to root produced green leaves. After an additional 20-day growth period, 82% of these cuttings produced roots.
