Abstract

The  functions of cotyledons are to do photosynthesis during the epigeal growth  to absorb, and to transport nutrients from endosperm to the growing sprouts. The morphology and the anatomy changes of cotyledons prior to the blooming of the first leaf showed that physiologis changes occured inside them. The aims of this research are to find out the morpho anatomy of cotyledons and the growth of the leaves during sprouting phase of green peanut sprouts applied in three different environments. This research was conducted in the structural and functional Biology Laboratory in FSM undip dated May 2014-july 2014. The research design was CRD (CompletelyRandomisedDesign) and the data were analyzed using ANOVA which has 95% validity. This research applied three different treatments were Dark (D), Medium (M), Bright (B) three times. The parameters observed were the morpho anatomy, the wet weight of cotyledons, and the leaf thickness of green peanut sprouts in three different environments. The research showed that the morphology and the anatomy of cotyledons were descriptively different on day 4 and day 8, not only in parekim cells of each group but also in the chlorophyl level and the amylum inside them. The wet weight of cotyledons and the leaf thickness were extremely different too when the sprouts aged 8 days.   Keywords : morphoanatomy, wet weight, cotyledon, environments

Abstract

Milkfish culture in silvofishery pond generally depend on environment services which is naturally provided by mangrove stands within. But, optimization of silvofishery structure for the growth of Milkfish is not well improved. This research aimed to know the growth rate of Milkfish in silvofishery pond occupying different stand population and species composition of mangrove and to analyze the difference of growth rate of Milkfish based on the applied treatments. Research was conducted for 4 months including treatments of L1V1 (5 stands of Avicennia marina); L1V2 (5 stands of Rhizophora mucronata); L1V3 (5 stands ofmixed species); L2V1 (10 stands ofA. marina); L2V2 (10 stands ofR. mucronata); L2V3 (10 stands of mixed species); L3V1 (15 stands ofA. marina); L3V2 (15 stands ofR. mucronata); dan L3V3 (15 stands of mixed species). Measurements on the growth of Milkfish were conducted through field sampling involving 30 samples of Milkfish for each treatment. Observed growth parameters including absolute daily length growth, absolute daily weight growth and specific growth rate (SGR). Data collections were conducted for 3 repetitions. Data analysis were conducted with t-test and ANOVA. The research resulted there were variation on the growth rate of Milkfish including absolute daily length growth, absolute daily weight growth and SGR based on growth period nor treatments. Analysis showed there were significant difference of absolute daily length growth and SGR between growth period, but not on the absolute daily weight growth. Growth period and stand population of mangrove simultaneously effect the absolute daily length growth and SGR of Milkfish. While species composition of mangrove species did not have significant effect to the growth of Milkfish.   Keywords: Milkfish, stands population, species composition, growth, silvofishery
