AGRICULTURAL BOTANY. 



The regeneration of seedling roots after splitting, Lura A. Warner i Rpt. 

 Mich. Acad. Sci., 6 | 1904), }>■ 78).'— An abstract is given of a report on experiments 

 with roots of beans, in which the regeneration after splitting is noted. When the 

 roots air split they assume a half-moon shape in cross section. This cross section 

 becomes rounded out by the formation of callus over the cut surface, and the 4 to 7 

 lihrovascular bundles w Inch are contained in the roots under normal conditions have 

 their functions taken up by about :i bundles after splitting. < Mherw ise t he regener- 

 ated root acts iii a perfectly normal manner. 



Notes on the regeneration of the hypocotyl of flax, Mary E. Hedden i Rpt. 

 Mich. Acad. Sci., 6 I 1904), />■ 79).— The effect of removing the cotyledons from flax 

 seedlings is shown, and notes also given on the conditions influencing the regenera- 

 tion of buds which develop below the cotyledons. Uninjured plants did not develop 



the buds in dry atmospheres, hut where the cotyledons were cut off, in the course of 

 a few days numerous buds were developed under both dry and moist conditions. 

 The number of buds produced was influenced by the age of the plant, the young 

 hypocotyls sending out from 1 to 60 buds, while on the old ones never more than 3 

 were formed. More buds developed in a saturated atmosphere than in a dry one. 

 and they developed very quickly at a high temperature. 



The experiments show that age, moisture, temperature, light, and season are all 

 important factors in influencing the formation of hypocotyl buds. 



The regeneration of the epicotyl in bean and pea seedlings, Arabel W. 

 Clare l Rpt. Mich. Ann!. Sci., 6 I 1904), p. 80).— A brief abstract is given showing 



the results of experiments carried on to ascertain the ability of bean and pea seedlings 

 to repair injuries.
