Experiments were made in which four different lines of Brussels sprout, each homozygous for S-allele 2, were tested for self-incompatibility at various stages of plant and flower development under different environmental conditions . The tests were made by counting the number of pollen tubes present

โฆ Synopsis
A study was made on the incidence of internal deviations in buttons of Brussels sprouts . Sprouts picked in the autumn showed an only slight degree of internal necrosis, in contrast to those picked in the winter . Large sprouts were more sensitive than smaller ones . No clear direct effect of nitrogen and planting distance could be established . Low temperatures in the winter are considered to be the main causal factor of this type of necrosis . Very distinct differences in sensitivity between varieties and strains were found . Probably resistant varieties may be bred by selection .
