This study was conducted to examine the effects of plug tray cell size and growth media on good seedling production of Gerbera hybrida Hort. Seedlings were grown for 60 days in 50, 72, 128, 162 cell trays contanning perlite, cocopeat and perlite+cocopeat(1:1, v/v). Perlite showed higher bulk density than cocopeat and perlite+cocopeat. Total porosity was greater in perlite, cocopeat and perlite+cocopeat in order. Cocopeat showed the highest water holding capacity. Number of leaves were greatest in 128 cell tray containing cocopeat. Leaf area was greatest in 50 cell tray containing cocopeat. Seedling growth was also better in plug tray of bigger cell size. Seedling growth of fresh and dry weight of shoot and root was much better in the growth media of perlite+cocopeat.

양액재배용 배지로 주로 이용되고 있는 것은 암면, 질석, 코코피트와 펄라이트 등이 있다. 이러한 배지들은 토양보다 가볍고, 이용가능성이 높아 양액재배에 많이 이용되어 왔다. 그러나, 암면, 질석과 코코피트와 같은 배지를 순환식 양액재배용 배지로 이용할 경우, 암면은 정상적으로 양분의 균형을 유지하는 것이 불가능하며, 질석과 코코피트와 같은 배지는 양분조절이 어렵고 장기간 사용할 경우에는 배지의 물리화학성이 변하는 단점이 있다. (중략)

This experiment was conducted to find out optimum substrate and concentration of nutrient solution for mass production of sweet basil by pot culture. Growth depending on concentration of nutrient solution was different to some extent; the growth of plants was usually better in one-fold and two-fold concentration of nutrient solution but three-fold one was poor. Plants grown in cocopeat showed better growth, but peatmoss gave an adverse effect. Sweet basil grown in substrate mixed with cocopeat and perlite (1:1, v:v) was highest in essential oil content. After all, cultural practice by one-fold concentration of herb nutrient solution in substrate mixed with cocopeat and perlite (1:1, v:v) was recommended for better growth and higher essential oil content of sweet basil.

In this study, we attempted to find substitute materials, swelling rice hull, cocopeat, corncob and coconut sawdust, for sawdust in bottle cultivation of Pleurotus ostreatus. Chemical characters of mixture substrates with four substitute materials for pine sawdust were not different significantly. By comparison in mycelial growth and yield of fruitbody, mixture substrate of cocopeat were showed the same level in P. ostreatus. Therefore, it is suggested that cocopeat was substituted for sawdust for cultivation of P. ostreatus.

This study was conducted to select proper substrate and nutrient solution concentration for favorable growth and quality in common thyme (Thymus vulgaris L.). The growth of common thyme was better in deep flow culture (DFT) than in other substrate cultures. As the nutrient solution concentration rose, the ratio of dry matter increased, while the fresh weight and the number of lateral shoots decreased. The contents of total chlorophyll and vitamin C were higher in DFT than others. Ca, K, P were showed high contents in cocopeat, but Mg content was the highest at half-fold concentration in DFT. Common thyme showed low content of nitrate in DFT compared with that in other substrate culture. DFT was the most effective system for pronoting growth and quality of common thyme. The optimal concentration of nutrient solution in common thyme was half-fold(EC=1.2mS/cm) of herbs nutrient solution by European Vegetable R&D Center.

This work is for selecting superior media which is similar to Peat Moss that is in general use as media of Gymnocalycium mihanovichii for Export such as 'Hwang wall' but lower price. The result on growth of 7 kinds of media (Peat Moss, BM6 Culture Medium, Coco Peat, Hydro Cray, Hydro Ball, Hugato, Vermiculite) which are applied watering (overhead irrigation, sub irrigation) based on bichemical analysis including chemical, physical analysis are following. The result of bi-chemical analysis shows that Coco Peat was stabilized planting after 90 days and Hydro Ball has high water holding capacity. The experimental result of growth in grafted cactus 'Hwangwall' shows Coco Peat is similar to Peat Moss on organic matter and in case of inorganic media, Hugato, Vermiculite, Hydro Cray made satisfactory results. But, the weight of inorganic media is too light to be tied. Consequently, Coco Peat and sphagnum moss as organic media has lower price and the condition of growth is analogous to Peat Moss. On the other hands, Hydro Ball was chosen as a substitute of Peat Moss in inorganic media.

Cellulose-degrading bacteria were isolated and identified from cocopeat which has a good quality as a bulking agent in composting. Various bacteria from different sourecs of cocopeat were detected on CMC agar media, and these were found to be Burkholderi2a sp., Bacillu subtilis, Sphingomonas sp., Rhodotorula sp. & Pseudomonas sp. etc. Among these, four bacteria were further selected and analyzed for their biochemical characteristics and CMCase activities. CMCase activities of four bacteria, P. aeruginosa, P. stutzeri, B. subtilis, and P. luteola were found to be 83%, 40%, 8%, 6%, respectively, compared with that of the standard strain Cellulomonas sp.
