Interstock Effect on Eureka-Trifoliate Incompatibility
No full text1. 珠心系檸檬接於不同枳殼之根砧上，所生不親和性亦各有不同，接於矮性枳殼砧， 並無不健康諸現象，惟接於強勢性枳殼砧，不親和性反高葉黃、脫落、矮化，至2- 3年後死亡。
2. 以晚崙夏橙為中間砧上接檸檬，下接強勢性枳殼砧，可阻止不親和性，此試驗業經5年研究。
3. 由各種不開發木之組合中， 可知不親和性之主因， 並非由枳殼根系，乃因檸檬與枳殼間組織發生極度不良所致。
4. 衰敗植抹澱粉僅存於接穗上， 根枳殼卻不存在。
5. 據生物化學研究， 氮素新陳代謝之不良現象，係樹勢衰敗之主因。
6 . 由於上述諸情況， 根據某種假說，即於檸檬接穗內，有某種物質產生，此物質可侵害枳殼組織， 惟以晚崙夏橙作中間砧，有吸收或改變枳殼組織物質之能力
The eradication projects and preventative control of quarantine pests in Okinawa, Japan
No full textOf the several exotic insect species in Japan, five quarantine plant pest taxa: the oriental fruit fly, Bactrocera dorsalis complex, the melon fly, Zeugodacus cucurbitae, the solanaceous fruit fly, Bactrocera latifrons, the sweet potato weevil, Cylas formicarius, and the West Indian sweet potato weevil, Euscepes postfasciatus, have been targeted in eradication programs using the male annihilation technique (MAT) and/or the sterile insect technique (SIT). Although all targeted fruit flies have successfully been eradicated, the incidences of re-invasion by Bactrocera dorsalis complex have been increasing in recent years, indicating the necessity for reinforcement and improvement of countermeasures for fruit fly re-invasion and/or recolonization. The program targeted at C. formicarius achieved the goal of complete eradication in Kume Island. The program for E. postfasciatus has yet to achieve eradication, even though it was initiated at the same time as that for C. formicarius. Major technical improvements are required for successful eradication of E. postfasciatus
