Derivatives Of

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.

Made In

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.

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.

Decaying Wood

Most species of grasshoppers in North America appear to lay their eggs in soil or among grass roots. A variation of this habit was reported in Manitoba by Criddle (1933) who states that Chloealtis conspersa Harr. and Neopodismopsis abdominalis (Thom.) oviposit exclusively in decaying wood or in dung.Recently, a few stems of sweet clover, Melilotus alba Desv., and Russian thistle, Salsola kali L. var. tenuifolia Tausch, that contained insect eggs, were sent to the Saskatoon Research Station by A. Vadeboncoeur of Val Marie in southwestern Saskatchewan. These eggs were laid in the pithy centres of the stems in groups of eight or nine (Fig. 1). According to the sender, the clover had been cut during the summer and the thistle was about two years old. Both were lying in the ditch on the railroad right-of-way. At our request, Mr. Vadeboncoeur sent in a few more infested stems. From a total of about 10 samples it seems evident that oviposition in plant stems is typical of the grasshopper involved. The exact egg-laying procedure is difficult to visualize in view of the small diameter of the pith (approximately 3 mm.), and the lack of any sign of penetration through the side of the stem. Inserting its abdomen into the narrow stem and depositing the eggs 25 to 30 mm. from the cut end of the stem must have involved considerable gymnastic manoeuvring by the female grasshopper.

In turkey, one of the most important problem of livestock’s production is insufficiency of quality forage crop, but still few forage species are cultivated. On the other hand, conservation of plant genetic resources has become an important problem in the world today. Indeed, biodiversity is an indispensable element of human life, especially food, and it is estimated that 20% of these resources will extinct by 2030. The aim of study was to determine some quality traits of white sweet clover (Melilotus alba Desr.) collected from natural flora of Bilecik province. In this study, plants were collected at the flowering stage and investigated of 17 genotypes. The determined quality traits of genotypes as fallows; crude protein, ADF, NDF, RFV, K, P, Mg, Ca and Ca/P, and these traits were noted as11.99-21.07%, 27.70-40.53%, 43.31-55.84%, 93.44-147.02, 1.300-2.807%, 0.187-0.310%, 0.127-0.350%, 0.490-1.417% and 2.05-5.92%, respectively. As a result of the study, it has been determined that the quality of the white sweet clover genotypes collected from Bilecik natural flora have been sufficient for animal feeding and have a significant potential for future breeding activities.
