Seeds of several Yucca species have been studied by Arnott and Horner. They mainly studied the nature condition and stated that the extra-embryonic food reserve tissue is a perisperm. This paper provides ontogenic evidence that this tissue is an endosperm with nuclear development type. The seed shape is nearly a triangular prism less than 1 cm long, black color and the raphe groove is conspicuous. The seed coat is derived exclusively from the outer integument. The exotesta external periclinal cell wall appears with irregular thickness. Both mesotesta and endotesta grow irregularly inward the seed confering to the endosperm a ruminate appearance. Toward seed maturity, the inner integument tissues disappear, thus fusion between intertegumentary and tegmen-nucellar cuticles occurs; valuable ontogenic information is showed by the cuticles, due to its persistence in spite of its generative tissue disappearance. The embryo development increases until 10 weeks after anthesis, it is cylindric, folds like "S" and two thirds of its chalazal lenght correspond to the cotyledon.

Plnctada albina breeds continuously throughout the year, but most actively during April and May when sea temperatures begin to fall. Thus the species resembles the majority of tropical marine invertebrates in the former respect but differs from them in the latter. The heaviest spatfalls occur from June to August when sea temperatures are at a minimum. This species is hermaphrodite, with a, general tendency toward protandry. Both male-female and female-male sex changes, and the bisexual condition which sometimes prevails during change-over, have been observed. Sex change in bivalves is discussed, and it is suggested that the phenomenon can best be explained in terms of a weak hereditary sex-determining mechanism, and germ cell rudiments responsive to the food reserve level in the body such that male differentiation is favoured at lower levels and female differentiation at higher levels.

ENGLISHFood reserve is very important to guarantee the fulfilment of the community’s consumption needs. The aim of the research was to analyse the domestic potential, the existing, and the coverage of community food reserve in the study area. This research used quantitative and descriptive approaches. The variables consisted of the potential, the existing, and the coverage of food reserve. Data were collected through interview and survey for the primary data. Meanwhile, the observation on the relevant documents was conducted to obtain the secondary data. Data were analyzed descriptively. The research had 9 findings. Firstly, the average of the domestic potential of the food reserve was 237,030,630.47 kg annually. Secondly, the existing of the food reserve at the licensed institutions was 4,107,861.28 kg. Thirdly, the potential proxy of the food reserve at the unlicensed institutions was 232,996,149.68 kg. Fourthly, the government food reserve was 14,904,773.4 kg. Fifthly, the total of the monthly community food consumption was 9,330,835.50 kg. Sixthly, the coverage of the potential of food reserve was 25.4 months. Seventhly, the coverage for existing of food reserve at the licensed institutions was 0.44 month (13 days). Eighthly, the coverage of the food reserve at the outside of licensed institutions was 24.96 months. Ninthly, the coverage of the government food reserve was 1.597 months (47.92 days). INDONESIACadangan pangan sangat penting untuk menjamin pemenuhan kebutuhan konsumsi pangan masyarakat. Tujuan penelitian adalah untuk menganalisis potensi domestik, eksistensi, dan coverage cadangan pangan masyarakat di lokasi penelitian. Penelitian menggunakan pendekatan deskriptif-kuantitatif. Variabel penelitian meliputi potensi, eksistensi, dan coverage cadangan pangan. Pengumpulan data primer dilakukan dengan menggunakan teknik wawancara dan survei. Sedangkan, observasi dokumen yang relevan dilakukan untuk memperoleh data sekunder. Analisis data dilakukan secara diskriptif. Penelitian ini memiliki 9 temuan. Pertama, rata-rata potensi cadangan pangan di area studi sebanyak 237.030.630,47 kg pertahun. Kedua, eksistensi cadangan pangan milik usaha pangan berijin sebanyak 4.107.861,28 kg. Ketiga, proksi potensi cadangan pangan milik masyarakat umum nonusaha pangan berijin sebesar 232.996.149,68 kg. Keempat, cadangan pangan milik pemerintah yang meliputi lumbung pangan daerah dan BULOG sebanyak 14.904.773,4 kg. Kelima, jumlah konsumsi pangan penduduk perbulan sebanyak 9.330.835,50. Keenam, coverage potensi cadangan pangan domestik sebesar 25,40 bulan (2,12 tahun). Ketujuh, coverage eksistensi cadangan pangan masyarakat pada lembaga berijin sebesar 0,44 bulan (13 hari). Kedelapan, coverage potensi cadangan pangan pada masyarakat umum sebesar 24,96 bulan. Kesembilan, coverage cadangan pangan milik pemerintah sebesar 1,597 bulan (47,92 hari).
