Establishment of a technique of high-quality fruit production of deciduous fruit trees: (2) Effects of the age of tree and tree vigor upon pollen germination of Japanese pears

落葉果樹の高品質果生産技術の確立 (2)ニホンナシの花粉発芽に及ぼす樹齢・樹勢の影響
Study period:2002 - 2004
Research overview:
Recently, lowering of the pollen germination rate of Japanese pears becomes a problem. Though vigor and the age of tree are guessed to be causes, few surveys have been conducted. In this study, effects of vigor and the age of tree upon the pollen germination rate are surveyed, and it is investigated how to supply high-quality pollen of a high germination rate.
