“…In addition, planting dates had a significant main effect on the seasonal average flower diameter of Cockscomb. Although pairwise comparisons revealed that the effect involved only two means, 4.28 cm 2 for the May planting and 3.67 cm 2 for the April seeding [14]. Planting from May to July might results reduced growth and immature flowers which affected on later flower formation that could be due to high temperature exposure or remaining in packs or flats too long in the spring when planted too early [17].…”

“…Celosia cristata L. or better known as Jengger Ayam is a member of the family Amaranthaceae which grows wide in South America, Africa, and Asia. This plant has a unique flower shape with variety of colors which is widely used for landscape ornamental plants, potted ornamental plants, as cut flowers and for decoration (Porat et al 1995;Taha and Wafa 2012). The chemical content of C. cristata consists of antioxidants and chemical compounds such as saponins, flavonoids, and betalains, and phenol glycosides (Zhang et al 2016).…”

Abstract. Muhallilin I, Aisyah SI, Dewi Sukma D. 2019. The diversity of morphological characteristics and chemical content of Celosia cristata plantlets due to gamma ray irradiation. Biodiversitas 20: 862-866. Celosia cristata L. or better known as Jengger Ayam is an ornamental plant that has a unique flower shape with attractive colors. Besides, this plant also contains antioxidants and chemical compounds that are used for traditional medicine to treat high blood pressure, and diabetes or as eye ailments. Increased diversity of C. cristata through hybridization techniques is constrained by flowers forming small grains that makes it difficult for castration and isolation of reproductive organs. This study aimed to increase C. cristata diversity of morphology and chemical content using mutation techniques induced by gamma irradiation. Plantlets were irradiated at 0, 25, 50 and 75 Gy doses. Scoring was conducted for 5 weeks until MV6 generation. Planlets were acclimatized for 3 weeks. The surviving plants were moved onto experimental land until seeded and tested for phytochemicals. Gamma irradiation with 25, 50 and 75 Gy doses produced 4 clones that have morphological changes in color and shape of the stem, leaves, and flowers. Changes in chemical content were observed with the appearance of triterpenoid compounds in 1 clone irradiated with 25 Gy.

“…The initial harvests began about 2 weeks earlier for wheat celosia than for cockscomb celosia, and wheat celosia provided four harvests compared with three harvests for cockscomb celosia. Porat et al (1995) reported that flowering of cockscomb celosia (C. argentea var. plumosa) is delayed under long photoperiods (>16 h).…”

Field-grown cut and dried flowers could provide a high-value crop selection for New Mexico. We conducted a 1-year field study to evaluate flower yield and quality characteristics of common globe amaranth (Gomphrena globosa), ‘Strawberry Fields’ globe amaranth (Gomphrena haageana), cockscomb celosia (Celosia argentea var. cristata ‘Chief Mix’), and wheat celosia (Celosia spicata ‘Pink Candle’). Within-row spacing of 15 or 20 cm combined with two-row or three-row per bed plantings resulted in field planting densities ranging from 66,670 to 120,010 plants/ha of common globe amaranth and ‘Strawberry Fields’ globe amaranth, and 100,005 to 200,010 plants/ha of cockscomb and wheat celosia. All but cockscomb celosia produced four harvests that began 22 May and ended 18 Oct., depending on species. Both globe amaranth species had a 5- to 6-month harvest season, two to three midseason to late-season peak harvests, and over 1000 harvested stems totaling 1.4 to 1.8 kg dry weight per 1.5-m2 plot across the season. Both celosia species had a 4.5-month harvest season, one early summer peak harvest, and fewer than 300 harvested stems totaling 0.6 to 0.7 kg dry weight per plot for the year. Seasonally progressive increases in flowering stem length of both globe amaranth species and wheat celosia, and in flowering stem diameter of both globe amaranth species and cockscomb celosia, were observed. Flowering head size of both globe amaranth species and of wheat celosia varied little with harvest season, whereas the head diameter of cockscomb celosia increased with the season. Postharvest flower retention after mechanical impact was about 2% higher for common globe amaranth than it was for ‘Strawberry Fields’ globe amaranth, decreased by about 6% from early to later harvests for both celosia species, and was inversely related to the head size of both globe amaranth species and cockscomb celosia. Despite the wide range in planting density, the density effect was largely limited to cockscomb celosia. For that species, three-row planting (high density) increased the total number of spray flower (multiple head) stems, provided longer stems later into the season and wider heads midway into the season, and prolonged the production of spray stems (15-cm spacing only). Results demonstrate that these four species are excellent candidates as new specialty crops in semiarid conditions.
