Evaluation of Adenium genotypes for physio-chemical and flowering characters

Abstract

Thirty three genotypes were evaluated for physio-chemical and flowering characters. Plant compactness was recorded maximum in Cross 6 (Arrogant × Vithoon’s White). Maximum chlorophyll a content of leaves (3.08 mg/100 g) was recorded in Cross 14 (Mor Lok Dok × Double Sweet Heart) and Chlorophyll b content of leaves (1.61 mg/100 g) was found in Cross 12 (Harry Potter × Vithoon’s White). Maximum anthocyanin content in petals (31.92 mg/100 g) was recorded in Cross 18 (Taiwan Dwarf × Deang Udam Sap). Maximum carotenoid content in leaves (5.04 mg/100g) was recorded in Picottee. Maximum superoxide dismutase activity (6.46 unit/g protein) was recorded in Cross 13 (Mor Lok Dok × Deang Udam Sap) and guaicol peroxidase activity (5.01 µ mol/min/g protein) was recorded in Cross 1 (Sudarshan × Deang Udam Sap). In-situ longevity (18.63 days) was observed maximum in Cross 15 (Picottee × Deang Udam Sap). Thus, Cross 6, Taiwan Dwarf, Cross 20, Cross 14, Cross 21, Cross 4 and Cross 5 has been found for plant compactness and Cross 15 and Cross 13 has been found for enhanced flower longevity.
