Barley seed rates

Ellinwood et al. (39) reported protection against mortality in mice by both PAPP and GSH. Ehrenberg (46) was able to detect significant protection of barley seeds against X-radiation by anoxia as well as hydrogen sulfide in respect to germination, fertility, growth, and mutation rate. Hol-laender et al. (24, 80) have found that anoxia and sulfhydryl compounds decrease the mutation rate in bacteria.

Time of sowing and seed rate. Early drilling of winter wheat and late drilling of winter barley and winter rye produce taller-strawed crops that are more prone to lodging. High seed rates produce crops with a narrow spread of roots that are more liable to root lodging. 

Few yield responses to application of Mo have been reported for either barley (Hordeum vulgare L.) or oats. Hawes et al. (1976) applied Mo at several rates to barley and wheat. The wheat showed increased yields, but the barley did not. Gupta and MacLeod (1978) found that barley would not respond to added Mo, but plant Mo concentrations increased with increased liming. One of the few responses to Mo was reported by Fitzgerald (1954). Yields increased from 39.5 to 58.5 bushels per acre with seed-applied Mo at 137 gha . Another early study (Gartrel, 1966) reported that oats and wheat would respond to Mo application. 

This chapter describes the development of H HR MAS NMR single seed measurements and the analysis will be exemplified in studies of wheat and barley. In order to assign H NMR signals to the various metabolites within the seed, both one-dimensional (ID) and two-dimensional (2D) NMR measurements were performed however, only ID spectra are presented in this chapter. Considerations about spinning rate, temperature and locking solvent are discussed, as these experimental parameters may influence the...
