Abstract

Environment aspect as requirement growing of oyster mushroom (Pleurotus sp.), give priority like temperature, relative humidity, time, CO2 and light. The parameter have different influence to each stadium or stage, for example mycelia growing on substrate, formation of fruiting primordia, formation of fruiting body, harvest cycle and BER (Biological Efficiency Ratio) value. pH medium have to regulated (betweenN6-7), incubation phase (22 - 28 O C ), humidity 60-70% and fruiting body phase 16 -N22 O C. Growing mycelium without light, growing fruiting body is needed light stimulant, light intensity 60 - 70 %.

Abstract

The sawdust can be utilized as mushroom formulation medium , like shiitake (Lentinus edodes /Lentinula edodes). The antitumor properties of lentinus are attributed to the presence of polysaccharide lentinan. Lentinan can be utilized as reducing diabetes, and effective to againts influenza virus. Usually, Albazia falcataria sawdust were utilized by mushroom growers in Indonesia. Optimum temperature for shiitake growth is 24oC and pH4.7 – 4.8 (mycelium phase), 20oC and pH 4.2 – 4.6.(fruit body phase). The elevation for best cultivation is 800 – 1000 m above sea level, humudity almost 95 – 100%. Ifused log system, shiitake will be harvested after 2-3 months fruiting bodies were produced. Biological efficiency (BER) was 45%.

Abstract

Saving the world genetic germplasm has been world community’s concern. It is a must to find a way to preserve Indonesian’s food plant biodiversity. In vitro technique culture is a proper alternative conservation of food plants. The technique is suitable for short viable seeds and vegetative multiplicating plants. Based on storage length, in vitro technique can be divided into two catagories. First short or medium term storage which intends to suppress the growth of the seed temporarily and secondly long term storage proposes to halt metabolic activity, however, the cells are still viable. There are some advantages of in vitro preservation such as savingdistinctive plants, foliage, plant without seeds, free pathogens, free disruption of environments. It is preserved free pathogen, and working on relative small room enough.
