TOMENTOSA USING THE BIOLOGISCHE BUNDESANSTALT, BUNDESSORTENAMT AND CHEMICAL INDUSTRY (BBCH) SCALE JF - Journal of Tropical Forest Science (JTFS) JA - JTFS VL - 35 IS - 2 SE - Articles DO - UR - https://jtfs.frim.gov.my/jtfs/article/view/2319 SP - 179-188 AB - <p><em>Rhodomyrtus tomentosa</em> var. <em>tomentosa</em> is a multipurpose flowering shrub in the Myrtaceae family. Naturally, this species thrives in the secondary forest areas and is cultivated as a garden plant due to its attractive flowers. The Biologische Bundesanstalt, Bundessortenamt and Chemical Industry (BBCH) scale was used to identify the phenological growth stages of <em>R. tomentosa</em>. A phenological observation on the organs of the plants was made at the Kepong Botanic Gardens, Forest Research Institute Malaysia, Kepong, Selangor. Branches with various developing plant organs were tagged to identify the principal and secondary growth stages and were photographed using digital camera. The observation was carried out daily for five months. Eight principal growth stages were recognised for <em>R. tomentosa</em>, namely, bud and leaf development, shoot elongation, flower emergence, flowering, fruit development, fruit maturity or ripening, and senescence beginning of dormancy. These principal stages were described and supported with images and growth duration. The developed BBCH scale for <em>R. tomentosa</em> will be a useful guide in improving landscape management and provide valuable information for scientific communications.</p> ER -
