Abstract

Comparative water relations of Quercus acuta and Castanopsis cuspidata var, sieboldii were analyzed to assess their resistance to drought and low temperature stresses from early November to early December, As air temperature decreased both species showed an increased content of osmotically active solute concentration per unit of dry weight (NS/DW), leading to lower osmotic potential of both species at both full turgid state $(OP_{sat})$ and turgor loss point $(OP_{tlp})$ in December than November. No major difference in the ability to adjust osmotically was noticed between the two. This finding suggests that both species must respond adaptively under water and low temperature stresses to maintain turgor pressure in winter season. In addition to osmotic adjustment, a low bulk modulus of elasticity $(E_{max})$ shown in Castanopsis cuspidata var. sieboldii must also play an important role in turgor maintenance during winter season being apt to happen water and low temperature stresses in plants.

상록활엽수의 저온스트레스에 대한 저항성과 내 건성을 파악하고자 대표적인 상록활엽수인 붉가시나무와 구실잣밤나무의 초겨울 비교 수분 관계 특성을 기온 변화와 함께 해석하였다. 10월 이후 강수량과 기온이 급격하게 감소하였으며, 이러한 감소에 대해 붉가시나무와 구실잣밤나무는 세포 내 용질의 양을 증가시켜 삼투 포텐셜을 저하시키는 삼투조절을 행하였다. 그 결과, 두 종 모두 원형질 분리점과 팽윤 상태에서의 삼투 포텐셜은 11월에서 보다 12월에 더욱 낮은 값을 기록하였으며, 이러한 삼투조절 능력은 같은 수분 포텐셜에서도 11월보다 12월에 더욱 높은 팽압을 유지할 수 있게 하였다. 또한, 구실잣밤나무는 이러한 삼투조절 능력에다 붉가시나무에 비해 세포벽 유연성을 높게 가짐으로서 겨울철의 저온 스트레스와 수분 스트레스 하에서 팽압을 유지하는데 기여하고 있는 것을 나타내었다.
