Simultaneous analysis of different classes of phytohormones in coconut (Cocos nucifera L.) water using high-performance liquid chromatography and liquid chromatography–tandem mass spectrometry after solid-phase extraction

Induction and Morpho-Ultrastructural Analysis of Organogenic Calli of a Wild Passionfruit

“…Coconut water, contains zeatin cytokinin, normally used to induce plantlet regeneration from the callus in plant tissue culture by stimulating the division of mature plant cells (Yong et al 2009). It also contains indole-3-acetic acid auxin (Ma et al 2008) that has the function of patterned differentiation of cells in meristems and immature organs (Uphade et al 2008) and the vitamin C, which prevents the oxidation and protects the calli and shoot tissues and vitamins that are watersoluble and are required as coenzymes for enzymatic reactions essential for cellular function (Ma et al 2008;Prades et al 2012). The above could explain the organogenic calli obtained in the present study.…”

“…The composition of coconut water, the liquid endosperm of coconut (Cocos nucifera L.), depends on factors such as the coconut variety, stage of maturity and cultivation practices (Prades et al 2012). Coconut water presents a unique chemical composition of sugars, vitamins, minerals, proteins, amino acids and phytohormones and it is extensively used as a growth-promoting supplement in plant tissue culture (Ma et al 2008;Yong et al 2009). Coconut water, contains zeatin cytokinin, normally used to induce plantlet regeneration from the callus in plant tissue culture by stimulating the division of mature plant cells (Yong et al 2009).…”

Analyses of Indole Compounds in Sugar Cane (Saccharum officinarum L.) Juice by High Performance Liquid Chromatography and Liquid Chromatography-Mass Spectrometry after Solid-Phase Extraction

“…To develop a new method for measuring indole compounds, the C 18 SPE cartridge was chosen since it provided good recovery performance in our previous phytohormone study which included a few indole compounds [37]. In the earlier work, the SPE was optimized to simultaneously pre-concentrate different classes of phytohormones in a single assay.…”

Pengaruh Pemberian Air Kelapa Dan Frekuensi Pemberian Terhadap Pertumbuhan Benih Cengkeh

“…Air kelapa mengandung asam amino, asam-asam organik, asam nukleat, purin, gula, vitamin dan mineral (Netty 2002;Ma et al 2008). Air kelapa merupakan senyawa organik yang mengandung 1,3 diphenilurea, zeatin, zeatin glukosida, zeatin ribosida, kadar K dan Cl tinggi, sukrosa, fruktosa, glukosa, protein, karbohidrat, mineral, vitamin, sedikit lemak, Ca dan P (Yong et al 2009) dan kinetin (Barciszewski et al 2007).…”
