Recent Breakthroughs in Postharvest Physiology Research and Cut Flower Handling in Japan
Kazuo Ichimura,Tetsuya Yamada,Hiroko Shimizu-Yumoto 한국원예학회 2009 Horticulture, Environment, and Biotechnology Vol.50 No.6
Senescence of flower petals has been reported to be controlled by genetically programmed cell death (PCD). Based on nuclear morphology and DNA degradation, which are parameters of PCD, we can categorize petal senescence for six plants into three types. In all plants, except for Prunus yedoensis, marked DNA degradation was observed during petal senescence. In morning glory, petunia and Argyranthemum frutescens, nuclear fragmentation occurred during PCD. In contrast, chromatin fragmentation in the nuclei was observed in carnation and snapdragon flowers. However, nuclear or chromatin fragmentation was not observed in P. yedoensis. In carnation flowers, PCD associated with petal senescence was shown to be highly regulated by ethylene. Wet transport is better than dry transport for maintaining the freshness of cut flowers, but the vase life of cut flowers is not markedly longer for wet transport than dry transport. Treatment with sucrose plus antimicrobial compounds before shipping and during wet transport extended vase life of rose flowers. This treatment was shown to be effective in extending vase life in practice for the transport of cut roses from Hokkaido and Chiba Prefecture to markets in Tokyo. Pulse treatment with silver thiosulfate complex (STS), an inhibitor of ethylene action, in combination with sucrose before shipping are followed by treatment with sucrose plus antimicrobial compounds during wet transport, extended the vase life of cut Eustoma, Delphinium and snapdragon flowers. This treatment was also confirmed to be effective in practice.
On 3-D Measuring Technique of Large structures
Hideyuki SAWADA,Kazuo ICHIMURA,Takakazu ISHIMATSU 대한전자공학회 1992 대한전자공학회 학술대회 Vol.1992 No.10
We present a system to measure 3-dimensional coordinates of large structures such as ships, buildings and oil tanks. Our system consists of two important units which are a laser spot pointer and a laser spot tracker. Employing a tactful image processing, our system has some features:e.g. downsize, cost, accuracy and robustness to hazardous environments.
