A simple technique was developed for estimating leaf surface area (A) of muskmelon with measurements of leaf length from the sinus base to the apex of leaf along midrib (L) and/or maximum leaf width (W) without the use of any expensive instruments. Leaves for three muskmelon varieties, Chioumih, Zhufen and Tianhun were collected from different levels of the canopy of plants during the growing season in 2007 at Taiwan Agricultural Research Institute, Wufeng, Taichung, Taiwan. Each leaf was measured for L, W and A. Data analysis were performed by regression technique. Results showed that differences in leaf shape among these varieties affected the performances of prediction accuracy in different models for leaf area estimation. The linear equations having W2 as the independent variable provided the most accurate estimation of A for Chioumih and Zhufen muskmelons, with leaf area coefficients of 0.70 and 0.62, respectively. For Tianhun muskmelon, the equation of A=0.67 × L × W exhibited the highest accuracy of leaf area estimation, and the equations of A=0.62 × L2 and A=0.71 × W2 could also be adopted. With these models, a high degree of 1:1 relationship was obtained between measured and predicted leaf areas, and they produced satisfactory results of lower mean squared deviation (in the range of 451 to 762), lower percentage of deviation for total leaf area (≦1.34%), and lower mean percentage of deviation for individual leaf area (≦0.25%). The linear regression model was simple, rapid, inexpensive and accurate for estimation of leaf surface area of muskmelon and nondestructive to plant growth.","PeriodicalId":159002,"journal":{"name":"Taiwan Agricultural Research","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114257321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Britton, a member of Lamiaceae and a native dicot in Asia, is now distributed worldwide including Taiwan. To further explore its uses as a commercial crop, a comprehensive study regarding the growth behavior and chemical components of this plant species is needed. In the present research, changes in growth traits, including plant height, leaf area index and weights of aerial parts, and leaf perillaldehyde (PA) concentration and content were investigated for plants grown in different growing seasons in the experimental period from 2004 to 2006. The five-leaf stage seedlings were transplanted in March (Season I), April (Season II), May (Season III) June (Season IV) and July (Season V), respectively. Concentration of leaf PA was determined by High Performance Liquid Chromatography (HPLC). Results showed that plant height was taller and leaf area index and fresh weights of aerial parts were larger for plants grown in cooler Season I relative to those plants grown in other warmer seasons (Seasons II-V), implying that warming conditions during growing periods was not in favor to plant growth. Seeds harvested at maturity were found varied in different growing seasons and seed produced in Season V was the lowest. In contrast, the highest value of 500-seed weight also obtained from seeds produced in Seasons V. The PA concentration in the primary leaves on the main stem from position 10 to 15 was higher than others and the quadratic pattern was similar in different growing seasons in 2004–2006. The distribution pattern of leaf PA content was in accordance with leaf PA concentration during the growing periods. In considering the proportions of PA distributed in leaves emerged on the main stem and the lateral branches, the proper time period to harvest the highest quantity of leaf PA for a single plant was from 110 to 120 days after transplanting.","PeriodicalId":159002,"journal":{"name":"Taiwan Agricultural Research","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134362348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Small flower buds produced little ethylene (0.12 nL g^(-1) hr^(-1)) and the production declined to being undetectable as the bud grew and became a floret. Ethylene production increased again as the floret began to senesce. A peak of ethylene production occurred (1.5 nL g^(-1) hr^(-1)) at the half senescent floret stage. The rises in ethylene production occurred after the start of floret senescence. Floret buds were more sensitive to exogenous ethylene than the floret, as it took 5 versus 7 days for senescence symptoms to appear at 0.03 nL mL^(-1) exogenous ethylene. The ethylene inhibitor, 1-MCP was effective in prolonging the vase life of both ethylene-treated and non-ethylene-treated cut sprays. When 1-MCP was applied again after 7 days to the same sprays, senescence symptom development was further delayed. Concentration of 1-MCP as low as 235 nL m^(-3) which was one fourth of the concentration recommended for commercial use extended vase life. Bud opening also increased following 1-MCP treatment in ethylene-treated sprays. No difference in response to 1-MCP treatment was found when the treatment was varied from 2 to 12 h and from 10℃ to 28℃. A treatment with 1-MCP was a useful tool to extend vase life of Oncidium cut flower sprays.","PeriodicalId":159002,"journal":{"name":"Taiwan Agricultural Research","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123953056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
