DIFFUSE POROUS FRUITWOODS

NOTE: unless otherwise specifically stated, all of the images shown on this
page are of 1/4" square end grain cross sections shown at 12X with the top
of the image towards the bark and the bottom towards the pith so that
earlywood is towards the bottom of the growth rings and latewood is towards the top

general characteristics of fruitwoods (NOTE: "fruitwoods" is not a homogeneous grouping in terms of anatomical characteristics. There are fruitwoods that are diffuse porous, others that are semi diffuse/ring porous, and even ones that are fully ring porous (such as some pieces of almond / Prunus dulcis)



MALUS species

Classic diffuse porous, distinct growth ring boundaries
pores tiny to uncountable, rays barely visible at 10X




     

     

     

     

     

     

 


PYRUS species

Classic diffuse porous, pores tiny to uncountable, rays barely visible at 10X
growth ring boundaries vague to distinct but generally discerable to the naked eye


   

   

 

 

     

   

       


PRUNUS species

most have stronger rays and larger/sparser pores than Malus and Pyrus species
growth ring boundaries range from clear to vague


       
almond --- often more semi diffuse porous than diffuse porous

     

     

   

     

     

     

   

   

     

   

     

 

     

     

     

       

     

     

   

     

     

     

     

   

     

     

     

     

 

   

     

   
thorny plum; these seem more semi diffuse porous than diffuse porous but they are fruitwoods and so are left on this page.

     

   

   


CITRUS species

Much larger/sparser poses than most fruitwoods and with vasicentric parenchyma
plentiful lines of what appear to be banded parenchyma
rays weak but clearly visible at 10X


   

   
Valencia orange / Citrus sinensis --- pores relatively sparse (for a fruitwood) and with vasicentric parenchyma and banded parenchyma (unlike Prunus species), rays barely visible at 10X; very similar for sour orange / Citrus aurantium except that the pore distribution is even sparser


PERSIA species

Much larger/sparser poses than most fruitwoods and with vasicentric parenchyma
rays weak but clearly visible at 10X, vague growth ring boundaries
