Production of anthocyanin noted on decortieation of 

 branches of Spiraea pruni/olia and S. paniculata. pp. 4, 24, 82

It is noted that, during the dry period in East Indies 

 and Ceylon, a reddening of the leaves of certain trees is 

 produced. Also classification of conditions under which 

 anthocyanin. appears. pp. 25, 92

Oxygen shown to be necessary for formation of pigment 

 by totally submerging radishes in sugar solution, with the 

 result that no pigment was formed. p. 117

 As anthocyanin develops, there is greater absorption of 

 oxygen ; the reverse is the case as plants lose the pigment.

Experiments made on gaseous exchange in red and 

 green leaves of Ailanthus. It is shown that respiration 

 in red leaves is much more active than in green.

An account is given of numerous experiments on 

 autumnal leaves, young red leaves, leaves reddened by 

 decortieation of branches, by attacks of insects and by 

 exposure to strong light. Results go to show that the 

 appearance of anthocyanin in the tissues is correlated 

 with accumulation of oxygen in the tissues. The dis- 

 appearance of pigment from the tissues is accompanied 

 by a loss of oxygen. pp. 91, 101, 117

From relationship between colour in leaves and fruits 

 in certain vines, author concludes that pigment is syn- 

 thesised in fruits, and not in leaves. p. 84
