Effect of stem length in the foliar analysis of rose bush for cut flowers
It is studied the variations of mineral composition of the leaves with stem length in the cultivars Visa, Ilona (long stemmed) and Mercedes (short stemmed). The variations found are important in several cases, specially for potassium in the long stemmed cultivars. It's concluded that stem length is a critical factor for foliar diagnosis of the rose bush. From the results obtained, it appears advisable to carry out the sampling on stems 70 cm in the long stemmed varieties and 40 cm in the short stemmed.
