| Abstract/Contents: | Monocotyledons of 104 spp. from 52 families (including Juncus inflexus, Luzula sylvatica and Italian ryegrass) were divided into 2 groups depending on the UV fluorescence behaviour of their cell walls. The unlignified cell walls of the 1st group (including the above spp.) fluoresced blue which changed to green with increased intensity after treatment with NH3 due to the presence of bound ferulic acid. The isolated cell walls of these spp. contained bound ferulic, p-coumaric and diferulic acids which were absent from the cell walls of the 2nd group. Seeds of Italian ryegrass cv. Marino, cocksfoot cv. Welta, Agrostis stolonifera, maize, red clover cv. Marino, white clover cv. Import H2, Persian clover cv. Import and Brassica spp. including marrow-stem kale cv. Maxilla and winter rape cv. Sollux were germinated on filter paper soaked in salt sol. of the same composition as Baltic Sea water at total salt conc. of 0.5-12.0 g/l. All the spp. used showed reduced germination with increasing salt conc. The most susceptible group were the 3 clover spp., which all showed c. 50% reduction in germination with 4 g salt/l and hardly any normal germination at higher conc. Germination of marrow-stem kale and cocksfoot was reduced by c. 50% with 6 g salt/l, with some normal germination at higher conc. Winter rape was the most tolerant of salinity with 70-75% normal germination at 10-12 g salt/l. Italian ryegrass, maize and A. stolonifera were comparable with rape except at the highest salt conc. The salt conc. needed to reduce germination by 10% were 1, 2 and 4 g/l in the susceptible, intermediate and tolerant groups, resp. The results showed that generalizations on the tolerance of plant families were not possible. At high salt conc., many of the clover seeds rotted, while the Brassica spp. and most of the grasses had a high percentage of abnormal seedlings and cocksfoot a high percentage of ungerminated seeds. |
