Abstract

Characteristics of leaf unfolding and flowering of 31 chestnut varieties cultivated in southern Korea was conducted to provide basic data for chestnut varieties improvement. There were slight differences among varieties in leaf unfolding time and leaf unfolding was late in 2010 compared to 2008 and 2009. Leaf unlolding took about 8 days to complete in 2008 and 2009, but that took about two weeks to complete in 2010. In 2008 and 2009, flowering beginning and flowering end of staminate flower occurred in early May and June, those were detained by low temperature of April in 2010. Although pistallte flower in flowering characteristics showed very similar to flowering period of staminate flower, The flowering beginning for pistillate flower was earlier approximately 20 days than for staminate flower.

본 연구는 밤나무 품종개량을 위한 기초자료를 제공하기 위하여 남부지방에서 재배되고 있는 31품종의 개엽 및 개화특성을 조사하였다. 개엽시기는 품종 간에 약간의 차이가 있었으며, 2008년과 2009년에 비해 2010년에 늦게 개엽되었다. 개엽 1단계부터 4단계까지 소요되는 기간은 2008년과 2009년은 약 8일 정도였지만, 2010년에는 약 14일 정도가 소요되었다. 개화특성에 있어서 2008년과 2009년의 경우, 암꽃의 개화개시와 개화완료는 각각 5월 초순과 6월 초순이었으나 2010년에는 늦은 개화개시와 개화완료를 나타내었다. 개화특성에 있어서는 수꽃도 암꽃과 동일한 경향이었으나, 개화개시는 수꽃이 암꽃보다 20일 정도 빠르게 나타났다.
