Morphological characterization and gamma irradiation effect on plant growth of Curcuma heyneana Val & Zijp

Curcuma heyneana or temu giring is mainly popular for medicinal and beauty purposes; however due to its attractive inflorescence, it potential ornamental plant. This study aims describe morphological characteristics examine gamma irradiation effect on plant growth of C. heyneana. The method applied was acute irradiation, with 6 doses 0 Gy (control), 10 Gy, 20 30 40 50 Gy; 3 replications, 15 rhizomes per replication. characterized as a perennial herb; light yellow; leaves lanceolate oblong; inflorescence separate shoot; bracts white green in lower part, pale dark pink tip upper part; flowers yellow labellum. It landscape, pot cut flowers. Irradiation treatment has been shown affect the growth. radiosensitivity test indicated that LD20 LD50 were approximately 67.15 respectively. - stimulated height leaf number. higher shoots multiplication stunted High frequency mutations noted; spectrum including deformation, apex splitted, narrowed, stiffed, wrinkled, twisted, variegation.
