Judul: Kontribusi vigor awal terhadap daya simpan benih jagung (Zea mays L.) dan kedelai (Glycine max L. Merr.)
Abstrak: Tujuan penelitian adalah untuk menentukan peranan vigor awal(Va) terhadap daya simpan benih, serta berusaha menemukan tolak ukur yang dapat menunjukan indikasi vigor awal baik yang dlpengaruhi oleh faktor "innate" atau pun "induced", dan bersama vigor benih oleh pengaruh faktor "enforcedr" (Ve) digunakan untuk menduga daya simpan benih. Juga neneliti kemungkinan masuknya uap etanol ke dalam biji, apabila benih didera dengan etanol 95 Persen dalam bentuk uap,

Judul: Kuantifikasi metabolisme benih pada periode I, periode konservasi dan awal simpan periode II untuk deteksi vigor genetik jagung
Abstrak: Penelitian terdiri dari 3 percobaan, yaitu (1) pe- nentuan vigor awal benih (Va) yang merupakan suatu perco- baan faktorial dengan menggunakan faktor varietas dan faktor pemupukan fosfat; (2) penentuan vigor konservasi sebelum simpan (Vgs) lot-lot benih yang diperoleh dari percobaan (1); dan (3) penentuan vigor awal sebelum sim- pan (V) lot-lot benih yang digunakan pada percobaan (1) dan (2). Tujuan penelitian adalah mempelajari kemungkinan mendeteksi vigor genetik jagung melalui kuantifikasi me- tabolisme benih berdasarkan penilaian viabilitas absolut mulai dari saat matang morfologi (MM) sampai dengan awal periode simpan. dst ...

Judul: Distribution and Diversity of Ectoparasite Mites on Geckos in Indonesia
Abstrak: Data on the diversity and dispersal of parasitic mites on house geckos in Indonesia are very scarce. In this work, the distribution and diversity of mites living on three species of house geckos, namely Cosymbotus platyurus, Hemidactylus frenatus, and H. garnotii collected throughout Indonesia, has been elaborated. Geckos and mites were captured and immediately preserved in 70% ethanol. Whole mount of the mites was prepared by clearing in lactophenol followed by mounting on polyvinyl lactophenol solutions. The SEM preparation was conducted to examine the detail morphological characters of the mites. The results showed that among 448 individuals of geckos, 221 geckos were infected by Geckobia mites. Prevalences of C. platyurus, H. frenatus, and H. garnotii infested by mites were 14.8%, 50.69%, and 79.6%, respectively. Three different spesies of Geckobia (G1, G2, and G3) could be differentiated; and based on similarities of their morphological characters to ones described in published literatures, Geckobia G2 is Geckobia glebosum and Geckobia G3 is Geckobia bataviensis while G1 could not be identified to the species level. The highest mean intensity of Geckobia G1 infestation was found on H. garnotii (I=7.0), G. glebosum infestation on H. frenatus (I=3.5), and G. bataviensis infestation on H. garnotii (I=11.8). In general, C. platyurus was infested by the least number of mites. Geckobia G1 were found living on the skin folds on the claws, G. glebosum were found mainly on the body and thigh, and G. bataviensis were found on almost all parts of the host’s body. Geckobia mites are distributed randomly throughout Indonesian Archipelago, following the pattern of distribution of their hosts. So it is concluded that Geckobia G1, G. glebosum, and G. bataviensis are sympatric.
