742 EXPERIMENT STATION RECOED. [Vol.35 



Garden Market, and numerous miscellaneous articles dealing with the culture, 

 care, and management of fruit under British conditions. 



[Report of horticultural investig'ations], R. S. Seton (Univ. Leeds and 

 Yorkshire Council, Agr. Ed. [Pamphlet] 96 {1915), pp. 50-56, fig. 1). — Fertilizer 

 tests with strawberries as well as variety tests with potatoes, bush fruits, rasp- 

 berries, and strawberries being conducted under the direction of the University 

 of Leeds are reported. An experiment being conducted with various lawn 

 mixtures is also outlined. 



Methods used in the propagation of plants, T. D. HAXFiErn (Trans. Alass. 

 Eort. Soc, 1916, pt. 1, pp. 89-102). — In this paper the author discusses the 

 different methods of propagation and their application in the propagation of 

 various classes of plants. 



Greenhouse heating (Neiv York: A. T. De La Mare Printing cf Publishing Co., 

 Ltd., 1916, pp. 52, figs. 2). — This comprises a reprint of four prize essays which 

 recently appeared in the columns of TJie Florists' Exchange. A digest of the 

 essays, together with comments by J. McArthur and a collection of answers to 

 questions on gi-eenhouse heating, is also included. 



Culture and forcing of Witloof chicory, J. W. Wellington (Neu- York State 

 Sta. Bui. 418 (1916), pp. 89-98, pis. S). — As a result of some forcing experiments 

 conducted at the station it is believed that Witloof chicory deserves much 

 greater attention at the hands of home gardeners and that at present prices it 

 can not fail to give good financial returns to market gardeners. 



This bulletin discusses the importance of Witloof chicory in Europe, its 

 culture and varieties, and describes in detail the cultural methods employed at 

 the station. The plants were easily grown from seed, and sand proved to be a 

 very satisfactory medium with which to cover the forcing roots. It blanches 

 the leaves perfectly and promotes the formation of compact heads. Roots hav- 

 ing a crown diameter within the limits of 1 to 2 in. produced the greater num- 

 ber of marketable heads. Temperatures ranging from 50 to 60° F. appear to 

 give optimum conditions for producing a marketable crop. 



Witloof chicory, F. H. Hall (New York State Sta. Bui. Jfl8, popular ed. 

 (1916), pp. 4, pis. 2). — A popular edition of the above. 



Transmission of resistance and susceptibility to blossom-end rot in to- 

 matoes, H. P. Stuckey (Georgia Sta. Bui. 121 (1916), pp. 83-91 figs. 3).— In 

 previous work at the station it was found that the cherry, pear, and currant- 

 tomatoes were immune to thp blossom-end rot (E. S. R., 26, p. 648). This bulle- 

 tin gives the results of crosses between the cherry type and a commercial 

 variety, with special reference to the transmission of resistance and suscepti- 

 bility to the blossom-end rot. 



The work indicates that both resistance and susceptibility are transmitted 

 from parent to progeny. The fruit of the Fi progeny of the cross between Red 

 Cherry (Ly coper sictim ccrasiforme) and the variety Greater Baltimore (L. 

 esculentum) was resistant to the blossom-end rot and was intermediate in size 

 and number of locules between the two parents, but tending toward that of the 

 cherry type. The Fa progeny was likewise resistant to the blossom-end rot and 

 varied widely in size of fruit and number of locules. At the same time no 

 distinct Mendelian segregation of these two characters was observed. 



Data are given showing the yield of a number of standard varieties and their 

 susceptibility to the blossom-end rot. The immune varieties were either very 

 early maturing or possessed cherry tomato blood. The Hybrid variety, the 

 plants of which are the first generation progeny of the cross between the 

 Red Cherry and Greater Baltimore, gave the highest yield of all the varieties,
