HORTICULTURE. 343 



A brief study of several kinds of beans with reference to relation of position 

 in pods to weight and desirability of the seed is reported on page 331, and 

 hypocotyl studies with various plants on page 331, together with a preliminary 

 study of shade as influencing the growth of plants in the open, and weather 

 notes for the growing season. 



Report of progress, B. H. A. Groth {Xew Jersey Stas. Rpt. 1912, pp. 403-Jt07, 

 pis. G). — ^A summary is given of the previous detailed report on the Fi heredity 

 of fruit characters in the tomato (E. S. R., 27, p. 742), together with a brief 

 statement of work done with the F2 and. Fa generations during 1932. The selec- 

 tion of many-celled and 2-celled fruits in the prairie berry (E. S. R., 28, p. 739) 

 was continued. From the records secured at the time this reiwrt was prepared, 

 however, high cell number does not appear to have been transmitted to the 

 offspring from manj'-celled fruits selected in 1911. 



Some additional data are given relative to the effect of various chemicals on 

 plants, although no deductions are made at this time. 



In the summer of 1909 some preliminary tests were made with various plants 

 in the summer heat of the greenhouse to determine which plants might be 

 favorable subjects for testing the permanency of environmental influence upon 

 characters of habit. Among other plants 4 varieties of bush beans were tested. 

 A decided change of habit attributed to excessive heat was produced in two of 

 these varieties, both of which began to run up to a height of 6 to 8 ft. on strings 

 like pole beans. No change in habit could be induced by the same treatment 

 with the other two varieties during the course of three generations. Pods were 

 taken at various heights from several plants of the varieties which had been 

 converted into climbers, and the seeds of each pod were grown separately in the 

 following summer under the same conditions. The seeds from the same plant, 

 all perfectly mature, developed into plants of different heights. In the work as 

 thus far continued, however, no direct relation has been traced between height of 

 seed on the parent plant and maximum height in the offspring. 



In previous studies of circulation In the sweet potato vine it was found that 

 a reversed water current coming from parts of the vine fruited in favorable sit- 

 uations was able to keep the sweet potato leaves perfectly turgescent (E. S. R., 

 27, p. 731 ) . An experiment, which is here outlined, is now under way to deter- 

 mine whether it is also possible to reverse the current of assimilated food 

 materials. 



A study of inheritance in g'arden plants, E. J. Owen (New Jersey Stas. Rpt. 

 1912, pp. 4O8-417, ph. 6). — The work in 1912 was conducted along the lines 

 noted in the previous year (E. S. R., 28, p. 740). Some general notes are given 

 on first generation crosses of beans, together with some data on cro.sses and 

 hybrids of eggplants. The yield limitation experiments with various vegetables 

 were continued. 



Some data on this work are reported for bush beans, eggplants, and tomatoes. 

 Aside from the results previously noted (E. S. R., 27, p. 741) there appears to be 

 a greater development of blossoms on plants which are the progeny of planta 

 which have borne only one fruit as compared with those which have borne a 

 full crop. 



American-grown paprika pepper, T. B. Young and R. H. Tbue ( U. S. Dept. 

 Agr. Bui. 43, pp. 24, figs, ii).— This bulletin reports the results of an experiment 

 undertaken to determine the feasibility of growing the Hungarian paprika type 

 of red pepper in this country. Introductory considerations deal with the his- 

 tory of paprika peppers, legal definition of paprika, botanical origin of paprika, 

 characteristics of American paprika as compared with the foreign product, and 

 commercial considerations. The cultural experiments which were carried out 

 in South Carolina are here discussed with reference to the prevailing climatic
