M. Yogev et al., HORMONAL INDUCED TRANSFORMATION OF THE TUBEROUS PURPLE NUTSEDGE (CYPERUS-ROTUNDUS L) INTO A TUBER-LESS PHENOTYPE, Israel journal of plant sciences, 44(1), 1996, pp. 19-28
Spraying benzyladenine and gibberellic acid over sprouting shoots of C
yperus rotundus L. did not adversely affect their aboveground developm
ent. However, the underground shoots (rhizomes) modified their potenti
ally positive gravitropic growth response into a negative one, to beco
me aboveground shoots. Under such conditions, virtually no tubers, the
dominant propagating and perennating units of C. rotundus, were forme
d. Field experiments, where growth regulator treatments were followed
by application of reduced rates of herbicide, open new possibilities t
o facilitate the control of this noxious weed.
