Changes in phytochemical contents in different parts of Clinacanthus nutans (Burm. f.) lindau due to storage duration Bragantia
Raya,Ketaren Bunga; Ahmad,Siti Hajar; Farhana,Sanusi Fatin; Mohammad,Munirah; Tajidin,Nor Elliza; Parvez,Anwar.
Clinacanthus nutans is a well recognized medicinal herb for its high phytochemical contents. Several aspects may contribute to the phytochemical contents, and thus determine the quality and efficacy of an herb. An experiment was conducted using a completely randomized design (CRD) with five replications, in a factorial arrangement of treatments. including two plant parts harvested at two different stages such as young leaves, young stems, matured leaves and matured stems, and four different storage durations such as 1, 2, 3 and 4 days. The study was aimed at determining how storage duration affects selected phytochemical contents of different plant parts of C. nutans at different harvesting stages. Total phytochemical content, total flavonoids content and...

Responses of Dendrobium 'darrenn glory' and Mokara 'calypso jumbo' orchids to 1-methylcyclopropene and aqueous ozone postharvest treatments Bragantia
Almasi,Parviz; Mohamed,Mahmud Tengku Muda; Anwar,Parvez; Ahmad,Siti Hajar; Kadir,Jugah.
AbstractOrchids possess a very special place amongst ornamental plants. But high ethylene sensitivity and early flower senescence of orchid result in a short vase life and rapid quality deterioration which is of great concern for the growers, traders and consumers. An attempt was made to study the influence of 1-methylcyclopropene (1-MCP) (0 and 300 nL L–1) and аquеous ozone (0 and 5.2 nL L–1) in prolonging vase life and maintaining quality of two cut orchid hybrids Dendrobium 'Darren Glory' (DDG) and Mokara “Calypso Jumbo” (MCJ). Results showed that orchid hybrids exhibited differences in their ethylene sensitivity, vase life, 1-aminocyclopropane-1-carboxylic acid (ACC) content and ACC oxidase activities. Pre-treatment with 1-MCP resulted in reduced...

Ripening characteristics of vapour heat treated ‘Frangi’ papaya (Carica papaya L. cv. Frangi) as affected by maturity stages and ethylene treatment Bragantia
Hasan,Fatimahtul Hazwani; Tajidin,Nor Elliza; Ahmad,Siti Hajar; Mohamed,Mahmud Tengku Muda; Shukor,Nur Indah Abdul.
ABSTRACT ‘Frangi’ papaya is a F1 hybrid cultivar produced by Malaysian Agrifood Corporation Bhd in 2006. Since then, ‘Frangi’ papaya is a new hybrid and its physiology may differ from another cultivars. Several importer countries, such as Japan and China, have made the vapour heat treatment (VHT) an export requirement for disinfestation of fruit flies in Malaysia. The exporting country is also required to carry out ripening treatments with ethylene before export. Therefore, the objective of this work was to determine the effects of maturity stages (4, 5 and 6) and ethylene treatments on ripening characteristics of vapour heat treated papaya during storage at 25 °C. Papaya fruits were treated with VHT systems. After VHT, the fruits were exposed with 100...

Production system and harvesting stage influence on nitrate content and quality of butterhead lettuce Bragantia
Yosoff,Siti Fairuz; Mohamed,Mahmud Tengku Muda; Parvez,Anwar; Ahmad,Siti Hajar; Ghazali,Farinazleen Mohd; Hassan,Hamizah.
Leafy vegetables such as lettuce grown under different production systems may accumulate different concentrations of nitrate which may reach to the levels potentially toxic to humans. Moreover, nitrate accumulation varies in various plant parts and physiological age of the plant. Therefore, to determine the effect of production system and harvesting stage on nitrate accumulation and quality of butterhead lettuce, a study was conducted considering two lettuce production systems namely hydroponic and organic, and four different harvesting stages such as 35, 38, 41 and 44 days after transplanting (DAT). The experimental design was complete randomized design (CRD) with four replications. Hydroponic and organic systems performed similar in terms of yield,...
