    EFFECT OF STORAGE TEMPERATURE AND SEED MOISTURE CONTENTS ON PAPAYA (Carica papaya L.) SEED VIABILITY AND GERMINATION
    (Journal of Sustainability Science and Management, 2013) ZULHISYAM A.K.; CHUAH TSE SENG; AHMAD ANWAR ISMAIL; N.N. AZWANIDA; SHAZANI, s.; JAMALUDIN, M.H.
    This experiment examined the suitable storage temperature and seed moisture content for seed storage of papaya (Carica papaya L.) cultivar of "sekaki". The seeds were dried to 6%, 8% and 10% moisture contents using silica gel and stored at O"C, 4°C and 28°C for three months. Seeds containing 6% moisture content and stored at OOC gave higher percentage of germination, lower dormancy, lower seed death compared to the seed ofthe other storage conditions. The result suggested that such condition was the best condition for papaya seed storage. Seeds containing 10% moisture content and stored at 28°C is not recommended for papaya seed storage because seed deterioration rate under such condition is higher within three months of storage.

    A STUDY ON THE ANATOMY FEATURES OF GREEN AND DARK BROWN BUFFALO LEECH (HIRUDINEA MANILLENSIS)
    (Journal of Sustainability Science and Management, 2014) ZULHISYAM, A. K.; JAMALUDIN, M. H.; SHAZANI, S.; MOHAMMAD AMIZI, A.; LEE, S. W.; MOHD SUKHAIRI MAT RASAT; M. MAZLAN; A. M. IQBAL; AHMAD ANWAR ISMAIL; N. N. AZWANIDA; M. MARWAN; M. FARHAN
    Leeches (Phylum: Annelida, Class: Hirudinea) are widely distributed all over the world in diverse habitats. In this study, the anatomy and features of Hirudinae manillensis or buffalo leech were observed and recorded. The external and internal anatomy of the leech was identifed to know if there exist any differences between the green buffalo leech and the dark brown buffalo leech. The internal and external anatomy features both green and dark brown leeches were similar. The external anatomy features observed were; body pattern, colour of the body, size of the body, size of the sucker, body length and width, mouth, number of teeth and eyes, absence of papillae and number of annuli while the internal anatomy features observed were; organ such as crop, rectum, male and female reproductive organ and testes sack can be found. In contrast, the colour and pattern of the dorsal and the abdominal was different between the dark brown buffalo leeches and the green buffalo leeches. The Green leech had simple pattern with 5 stripes from a combination of 3 different colours namely green, brown and black, while the dark brown leech had a much more complex pattern with square shapes pattern on the dorsal.
