  • A popular roselle variety planted in Malaysia, aka variety Terengganu. Roselle fruits are harvested fresh, and their calyces are made into a drink rich in vitamin C and anthocyanins.

  • Two varieties are planted in Malaysia (Left - variety Terengganu or UMKL-1; right - variety Arab. The varieties produce about 8 t/ha (3.6 short tons/acre) of fresh fruits or 4 t/ha (1.8 short tons/acre) of fresh calyces. On the average, variety Arab yields more, and with higher calyx to capsule ratio.

  • Dried roselle calyces can be obtained in two ways; one way is by harvesting the fruits fresh, decore them, and then dry the calyces; the other way is by leaving the fruits to dry on the plants to some extent, harvest the dried fruits, dry them further if necessary, and then separate the calyces from the capsules

  • Roselle calyces can also be processed into sweet pickle. This is usually produced as a by-product of juice production. However, quality sweet pickle may require a special production process.

  • Variation in flower colour of roselle (a tetraploid species)

  • Calyx - a collective term for sepals of a flower; Epicalyx - a collective term for structures found on, below or close to the true calyx, also called false calyx. Some varieties show pronounced epicalyx structures, such as found in variety Arab. (Plural calyces)

  • Decoring — removal of a seed capsule from the fruit using a simple hand-held gadget to obtain its calyx

  • Some breeding lines developed from the mutation breeding programme at UKM

Famous quotes containing the word gallery:

    “I never can pass by the Metropolitan Museum of Art in New York without thinking of it not as a gallery of living portraits but as a cemetery of tax-deductible wealth.”
    —Lewis H. Lapham (b. 1935)

    “I should like to have seen a gallery of coronation beauties, at Westminster Abbey, confronted for a moment by this band of Island girls; their stiffness, formality, and affectation contrasted with the artless vivacity and unconcealed natural graces of these savage maidens. It would be the Venus de’ Medici placed beside a milliner’s doll.”
    —Herman Melville (1819–1891)

    “Each morning the manager of this gallery substituted some new picture, distinguished by more brilliant or harmonious coloring, for the old upon the walls.”
    —Henry David Thoreau (1817–1862)
