In crosses involving derivatives of interspecific crosses of (Melilotus alba × Melilotus dentata) and (M. officinalis × M. alba) with pure Melilotus alba, irregular ratios were shown to be common. Previous studies using pure M. alba have indicated simple Mendelian inheritances for many of the characters studied herein. However, when interspecific derivatives are involved, some plants give F2 families that do not fit any Mendelian ratio. Data are presented indicating that in segregations where the deficiency occurs it is always in the genotype that has contributed the gene from the non-recurrent species. Investigations carried out in this study are designed to determine possible causes for these "blurred" ratios.

The first record of the occurrence in North America of the white-tipped clover case-moth, Coleophora frischella L., was made in June 1966 when a single adult was taken by Heinemann on Picton Island, N.Y., in the St. Lawrence River (Freeman, personal communication). Independently, Trieselmann collected the larvae from white sweet-clover, Melilotus alba Desr., on 28 July through to 8 August 1966 at many points around Pembroke, Ont. Detailed examinations made at two of the collection points indicated that between 15 and 20% of sweetclover seeds were damaged. Because of its potential economic significance, the authors wish to make the presence of this species known to agricultural entomologists in Canada and the United States.

Selection Of

The chief determining factor in spontaneous self-fertilization in white sweet clover (Melilotus alba) appears to be the distribution of pollen within the unopened flowers. This in turn depends on (1) length of stamens, (2) length of style, (3) amount of pollen, and (4) size of cavity within the upper part of the keel. When the flower structure and quantity of pollen is such as to insure the deposition of pollen grains on the stigma before the blossom is likely to be disturbed by insects, the plant will be normally self-fertilized. In the yellow flowered species of sweet clover (Melilotus officinalis) spontaneous self-fertilization is effectively prevented, except in certain varieties, by a characteristic of the stigma which makes it unreceptive. Scarification of the stigmatic surface appears to be necessary before fertilization can take place. Variation occurs also, as in M. alba, in the length of stamens and style, size of keel cavity, and the amount of pollen.There is a high correlation in M. alba between the percentage of flowers which are naturally self-pollinated and the percentage of flowers which produce pods when the plants are caged to exclude insects. Selection of plants which are normally self-fertilized can be made by examining the early flowers, thus obviating the necessity of bagging or caging plants which do not possess this character.A strain of M. alba which is normally self-fertilized was found to produce almost twice as much seed as another strain which is normally cross-pollinated under comparable conditions in the field.

In Victoria, self-incompatible Amyema miraculosum may exist as a locally obligate parasite on partially self-compatible Amyema miquelii. For the first time, the pollination ecology of a mistletoe on a mistletoe is analysed. Both species were generalist ornithophiles with overlapping flowering seasons from January to March. Consequently, the hyperparasite was in competition with its congeneric host for pollen vectors belonging to the local nectar bird guild (Meliphagidae and Zosteropidae). Amyema miquelii produced flowers that were longer-lived, and had a higher nectar content, than those of A. miraculosum. From mid February through March, A. miquelii plants offered more inflorescences, with open flowers, than A. miraculosum. There was an average of twice as many flowers on an A. miquelii inflorescence as on an A. miraculosum inflorescence, Not surprisingly, more than 70% of avian foraging bouts observed were to A. miquelii only. Eight bird species foraged for nectar on A. miquelii while only five were recorded on A. miraculosum. While 22% of all foraging bouts were interspecific, no examples of interspecific hybridization were found. This corresponds with previous observation of the reciprocal failure of interspecific crosses in vitro.

Stimulation Of

Sweet clover (Melilotus alba Desr.) in pot culture was grown with and without applied sulphur and nitrogen fertilization, and with and without inoculation with Rhizobium metiloti. The nitrogen was applied as NH4NO3 at rates equivalent to 0, 100, 200, 300 and 400 pounds per acre. Inoculated plants treated with sulphur contained a significantly higher percentage nitrogen than sulphur-deficient plants, provided NH4NO3 did not exceed the 100-pound rate. This condition was reversed when NH4NO3 was applied at the 400-pound rate. These data indicate that sulphur-deficiency restricts growth through its effects on the nutrition of the host legume, rather than through the stimulation of nodule bacteria.With applied sulphur but no NH4NO3 inoculated plants fixed the equivalent of 164 pounds of nitrogen per acre in a 75-day growing period. Application of NH4NO3 depressed fixation and nodulation.
