Effect of Boron and Calcium on Growth and Quality of ‘Easy Lover’ Cut Rose

Abstract

2 This study was conducted to determine the effects of boron (B) and calcium (Ca) treatments on growth, quality, and mineral concentration of 'Easy Lover' rose grown in soilless culture. The experiment was arranged in a factorial based on a randomized complete block design with four replications. Treatments were consisted three levels of B (25, 50 and 75 µM) and three levels of Ca (2.5, 5 and 7.5 mM). Increasing B and Ca concentration in nutrient solution improved root development. The tallest stems were obtained from the application of 75 µM B and 7.5 mM Ca. Application of B and Ca showed a further increase in stem diameter, with the thickest stem caused by 50 µM B and 7.5 mM Ca. Plants receiving 50 µM B and 2.5 mM Ca had highest number of flowering stem. High Ca level in the nutrient solution antagonized the B concentration in leaf and petal.

Calcium Chelated with Amino Acids Improves Quality and Postharvest Life of Lisianthus (Eustoma grandiflorum cv. Cinderella Lime)

“…Similar results were also indicated in a study on alstroemeria (Smith et al, 1998). On the contrary, Shams et al (2012) indicated higher number of stems following the application of higher levels of calcium in cut roses (Shams et al, 2012). Although some researchers have attributed the increased number of stems to higher levels of calcium supply, Smith et al (1998) and Bar-Tal et al (2001) asserted the absence of a significant relation between calcium levels and number of stems.…”

“…However, we could not establish any significant differences in shoot number and length between various groups. In contrast, Shams et al (2012) reported treatment with high levels of calcium (7.5 mM) to maximize the length of the flowering stems in roses (Shams et al, 2012). Some researchers have also introduced the hormone-like activity and nitrogen content of amino acids to be responsible for growth promotion in plants (Madrid et al, 2003;Yeoh and Troung, 1996).…”

Integration of Transcriptome, Proteome, and Metabolome Provides Insights into How Calcium Enhances the Mechanical Strength of Herbaceous Peony Inflorescence Stems

“…Accordingly, exogenous Ca treatment is typically employed to regulate gene expression, maintain cell wall integrity, and improve plant growth and development [5,6]. Exogenous Ca treatment has also shown increased stem diameter in roses ( Rosa hybrida L.) [7], enhanced stem firmness of chrysanthemum ( Chrysanthemum morifolium Ramat) [8]. Moreover, exogenous Ca treatment delayed stem bending in gerbera ( Gerbera jamesonii cv.…”

Influence of Various Holding Solutions on Vase Life of Chrysanthemum Cv. Puja

“…Higher calcium concentration in the nutrient solution will be associated with greater stem diameter and dry weight (Picchioni et al, 2001). High calcium concentration (7.5 mM) in the nutrient solution has been reported to increase the diameter of the flowering stem in roses (Shams et al, 2012). It can in fact be concluded that the application of calcium amino acid (particularly lysine) chelates can promote the absorption of calcium by the flowering stem and hence increase flower and shoot diameter in comparison with control plants.…”
