Effect of In Vitro Culture Environments and Culture Methods on Cormlet Formation of Gladiolus, by Vathany Thun, Dae-Hoe Goo, Min Hee Kim, Mi Soon Byun and Kiu Weon Kim. Hort. Environ. Biotechnol. 49(2):114-120. 2008.
បរិយាយ:
Abstract
 
Five gladiolus cultivars 'Adlib Scarlet', 'May Queen', 'Pacific Pink', 'Sharone' and 'White Race' were used in order to identify their specific culture environments and culture methods to obtain cormlets from a shoot base in vitro. There was a cultivar-by-medium-temperature interaction effect. The solid medium was appropriate only for cormlet formation of 'May Queen', while liquid medium was favored for the other four cultivars. The best culture enviroment for cormlets formation of 'Pacific Pink', 'Sharone' and 'White Race' was liquid medium treated at 20℃. Fresh weight of cormlets of 'Adlib Scarlet' was highest when grown in liquid medium treated at 25℃. There was no difference among the three temperatures for cormlet formation of 'May Queen' which grew best in solid medium. The suitable light intensity was 68 μ㏖ㆍm-²ㆍs-¹ PAR for 'May Queen', 'Sharone' and 'White Race', 34 μ㏖ㆍm-²ㆍs-¹ PAR for 'Adlib Scarlet' and 135 μ㏖ㆍm-²ㆍs-¹ PAR for 'Pacific Pink'. Increase in fresh weight was related to increased diameter regardless of different temperature, light intensity, media, or cultivar.

A case study on farmer's choice of direct seeding and transplanting in rainfed lowlands in Northeast Thailand and Northwest Cambodia, by Akihiko Kamoshita,Sareath Chea,Satoshi Hayashi. Tropical Agriculture and Development Vol. 53 (2009) No. 2 P 43-54
បរិយាយ:
Abstract
Adoption of direct seeding of rice via dry-seed broadcasting (DS) was surveyed in rain-fed lowland in Northeast Thailand and Northwest Cambodia from 2003 to 2005. Based on interviews with village chiefs, nine villages in the target area were categorized into three types in relation to their field characteristics and rates of DS adoption. Village type I was identified with DS adoption of more than 80% in low and flat areas in Northeast Thailand, where DS was introduced from the late 1980s to early 1990s, and characterized by earlier planting in April or May, low weed infestation, and by high yields. Type II was identified with DS adoption of 6 ∼ 30% in undulating areas in Northeast Thailand, where DS was introduced from the late 1990s to early 2000s. This was characterized by a yield level lower than that in transplanting (TP) and a lack of effective weed control. Type III was identified in Northwest Cambodia, where extensive and low-yielding DS had popularly been practiced in remote, large, low and flat fields. DS is started from April to May like as that in type I, but the harvest lingered from mid-November to mid-January. In this type mid-season tillage was practiced to control weeds according to farmers’ knowledge in ecologically harmonized ways. Furthermore, 23 farmer fields were monitored, and grouped into three types in Northeast Thailand and six in Northwest Cambodia, depending on the planting methods, availability of field water and time of harvesting. In addition, three on-station experiments were conducted to compare yields between DS and TP. As the results, DS yielded comparable or higher than TP under favorable conditions, while DS yielded less than TP in cases with low availability of water and severe weed infestation.

Large-Sized Cormlet Induction and BYMV Removal through Tissue Culture in Gladiolus, by Vathany Thun, Mi Soon Byun, Dae Hoe Goo, Kiu Weon Kim. Hort. Environ. Biotechnol. 49(5):332-335. 2008.
បរិយាយ:
Abstract
 
Gladiolus 'Adlib Scarlet', 'May Queen', 'Pacific Pink', 'Sharone' and 'White Race' were used as plant materials in order to obtain large-sized cormlets from a shoot base in vitro for enhancing survival rate after soil transplanting, and large cormel tips in size 1 ㎣ were used as explants and subcultured for five to six times to remove the bean yellow mosaic potyvirus (BYMV) for enhancing efficiency of tissue culture. Cormlets were the largest in 9% sucrose compared to glucose, fructose and glucose+fructose in all cultivars tested. The 1:2 NH₄+:NO₃- ratio in MS solid medium containing 9% sucrose was the best for enlarging cormlets in almost all cultivars; hence, decrease of NO₃- concentration in MS medium is needed. Plantlets without cormlets did not survive in greenhouse. Cormlets produced in solid medium were sprouted 100% and grown to vigorous plants in all cultivars. Survival rate was 30~85% by cultivars in cormlets obtained in liquid medium. Maintenance of the plantlets in MS solid medium is needed prior to their transfer to soil for enhancing survival rate. Though the cormlets were obtained from large-sized cormel tip, BYMV were removed through subculture for five to six times.
