摘要
本文着重从以下几个方面验证了新研制的气孔计测定结果的可靠性。1.气孔计测定值与印迹法测量结果相比较,证明两者呈直线正相关,相关系数为0.97;2.气孔计测定值与渗入法测量结果相比较,证明两者也呈直线正相关,相关系数为0.98;3.气孔计测定的日变化曲线与蒸腾强度的日变化曲线相吻合;4.对同一叶片上、下表皮的测定结果也表明:气孔计值能够客观地反映气孔开度。
The new porometer's measurements were tested and verified from the foursides,1.The new porometer's measurements comparing with the resuIts of the stoma printsof gelatin shows that the two methods agree with each other.The interrelation coefficient is0.97.2.The new porometer's measurements are bound up with the results of sol permeation.Theinterrelation coefficient is 0.98.3.The veriating diagrams from sunrise to sunset testedby the new porometer and a transpirometer show no difference.4.The measurements testedwith the two sides epidermis of the same leaf show the new porameter can objectively reflectthe opening of the stomas.
