Our objectives were to assess the efficacy of various plant growth regulators (PGRs) on stem elongation and branching of 11 kalanchoe (Kalanchoe) species with ornamental characteristics: beauvard’s widow’s-thrill (K. beauvardii), K. glaucescens, lavender scallops or red-leaved kalanchoe (K. fedtschenkoi), K. longiflora, chandelier plant (K. manginii), marnier’s kalanchoe (K. marnieriana), K. millotii, flower dust plant (K. pumila), K. rosei, common kalanchoe or nentabos (K. rotundifolia), and K. streptantha. Foliar spray applications of deionized water, ancymidol (15−60 ppm), benzyladenine (75−300 ppm), chlormequat chloride (750−3000 ppm), daminozide (1250−5000 ppm), ethephon (250−1000 ppm), paclobutrazol (10−40 ppm), or uniconazole (5−20 ppm) were applied 2 weeks after plants were pinched. Stem length at the time of application and 4 weeks after applications and branch number were recorded. While effective chemicals and concentrations varied widely among species, paclobutrazol and uniconazole were identified as providing broad efficacy with respect to inhibition of stem elongation across all 11 species in this study. Additionally, benzyladenine and ethephon increased the number of branches for several species.

“…The 'Coral Prince' cultivar produced higher (54.4 cm on average), more leafy plants (139.3 leaves) than the 'Pigeon Red' cultivar (respectively: 43.4 cm, 88.4 leaves) with a larger rosette diameter. Also, in the study of Gibson and Whipker (2001), 'Coral Prince' formed taller plants with a larger diameter than 'Pigeon Red' (31.6 cm and 40.9 cm vs 27.8 cm and 36.1 cm, respectively).…”

“…In 2010, the diameter of the colourful rosettes represented an average of 59.8% of the total, while, in 2011, it was only 30.5% (Table 5). In order to achieve full decorative qualities, the effects of low temperatures should last about 2-3 weeks (Whipker et al 1998;Gibson et al 2001). In September 2011, the average 10-day temperatures were: 15.4, 16.3 and 14.0 °C (Table 1).…”

“…High summer temperatures cause excessive stem growth and weaker colouration, therefore, growth regulators, that affect not only the height of the plants, but also the diameter and size of the coloured rosette, are often used for cabbage growing (Whipker et al 1998;Gibson, Whipker 2001;Mello et al 2010).…”

Ornamental cabbages are cultivars of cabbages grown for decorative purposes due to the varied shape and colour of their internal leaves. The aim of the study was to determine the course of growth and to assess the decorative and nutritional value of two cultivars of ornamental cabbage (‘Pigeon Red’, ‘Coral Prince’) grown in a flowerbed along with annual plants: the French marigold (Tagetes patula nana L.) and flossflower (Ageratum houstonianum Mill.), using a pine bark mulch. The impact of the marigold and flossflower on the cabbage height and foliage changed with the plant growth. Cabbages growing without the proximity to the other species had the smallest diameter and formed the least leaves; and the plant’s height was lower in September. The cabbage height, foliage and leaf colour were modified by the weather in the subsequent years of research. The proximity of the marigold or flossflower and mulching of the soil with bark did not affect the colour of the leaves. The nutritional value of the ornamental cabbage was high, and the content of the mineral components in the leaves depended largely on their colour. The coloured leaves were more abundant in nitrogen, phosphorus, potassium and magnesium, while the green leaves contained more calcium and sulfur, and slightly more dry matter.

In order to increase the quality and yield of ornamental plants, especially potted ornamental plants, it is necessary to enrich the physical properties of the growing medium and to ensure the continuity of the growing medium. In order to achieve this, organic substances that create a serious cost in ornamental plant cultivation are added to the growing medium. This study was planned to assess the role of inoculation of different levels in the seeds and soaking times of purified phytase, on the plant growth and ornamental plant decorative values in ornamental cabbage plants under nutrient limiting condition in greenhouse. Different doses (E0: 0 EU, E1: 5 EU, E2: 10 EU), soaking times (W15: 15 min, W30: 30 min, W60: 60 min), and their combinations (W15 + E0, W15 + E1, W15 + E2, W30 + E0, W30 + E1, W30 + E2, W60 + E0, W60 + E1, W60 + E2) of phytase enzyme purified and isolated from the Lactobacillus coryniformis were applied to ornamental cabbage seeds, and they were sown in plug trays filled with appropriate growing medium. Seedlings were planted in plastic pots during their period when the seedlings had four to five true leaves. Treatments of phytase enzyme purified and isolated from the microorganism generally improved the observed parameters. The application of, especially, the highest level of phytase enzyme doses increased the plant height, main stem height, and stem diameter of ornamental cabbage as compared to control (E0 treatment: distilled water). While the highest number of leaves per plant was obtained at E1 and E2 application doses and W30 and W60 soaking times; the highest stem diameter was obtained at E2 application doses and W30 and W60 soaking times. The present study clarified that the purified phytase enzyme can increase ornamental cabbage quality at the appropriate concentration and soaking time and is a promising biotechnology material for agricultural applications, and especially in different ornamental plant species.
