Ethephon [(2-chloroethyl) phosphonic acid, Ethrel, Composan] was evaluated in field trials as a chemical hybridizing agent on four varieties of palmarosa (Cymbopogon martinii): PRC-1, Tripta, Trishna, and Composite. Application of 500 µg/ml ethephon to foliage either as a mist or by wrapping ethephon-soaked cotton around the stem during the vegetative and anthesis stages initiated increases in growth and yield attributable to heterosis. A positive correlation (r2 = 0.81) between ethephon application and yield of dry matter and ethephon application and essential oil with enhanced geraniol levels was obtained, suggesting ethephon treatment is an effective chemical hybridizing agent in palmarosa. Ethephon also appeared to stimulate ethylene production in flowers of palmarosa, resulting in male sterility and premature anther-petal senescence. [ABSTRACT FROM PUBLISHER] |
