Abstract:

Adenium is one of the popular flowering pot plant, with great relevance in the ornamental market due to its sculptural aspect, resistance to drought stress along with very showy flowers. A varietal evaluation of Adenium obesum was conducted with 11 different genotypes to evaluate their performance as potted ornamental plant under soilless culture. Experiment was conducted with three replications in Completely Randomized Design during the year 2015-16 and 2016-17 at the Advanced Technology Centre of Soilless system for various crops, ACHF, NAU, Navsari. The growing media consisted of mixture of cocopeat, cocofibre and Styrofoam (6:2:1). Plant growing habit and flowering attributes are important parameters for ornamental pot plant value. Plant height was observed minimum in Taiwan Dwarf (33.90cm and 33.58cm), followed by Mor lok Doc while Local variety showed maximum plant height (78.54cm and 75.65cm). Maximum number of branches per plant was recorded in Taiwan Dwarf (8.20 and 8.69) that was at par with Mor Lok Dok and Vithoons White in both the years i.e. 2015-16 and 2016-17. Maximum caudex diameter at the time of flowering was observed in Mor Lok Doc (40.32cm and 42.58cm) followed by Taiwan Dwarf variety in both the years. The leaf area was measured highest in Arrogant (26.13cm2 and 25.90cm2) which was at par with Deang Udam Sap whereas the lowest leaf area was measured in Picottee in both the years. Var. Deang Udam Sap showed significantly superior red flowers with maximum diameter (9.15cm and 9.1cm) which was on the same bar with pink coloured variety of Harry Potter. Further, diameter of corolla tube was also maximum in Deang Udam Sap (2.32cm and 2.35cm), followed by Arrogant in both the years. Length of corolla tube was also maximum in Deang Udam Sap (4.01cm and 4.14cm) and Arrogant followed by Vithoons White during both the years. Maximum flower weight was observed in variety Deang Udam Sap (2.62g and 2.44g), followed by Double Sweet Heart. Number of petals was 5 in all varieties except in Double Sweet Heart which looked showy with dual whorl having ten petals. The variety Deang Udam Sap recorded significantly highest flowers per cluster (14.10 and 14.23) as well as clusters per plant (12.13 and 12.64) that was followed by Double Sweet Heart and Harry Porter during both the years. In situ flower longevity was observed maximum in Deang Udam Sap (11.67days and 11.45days) and Double Sweet Heart (11.47days and 11.854days), followed by Arrogant and Harry Porter.
