There is no evidence of clinal variation; this was confirmed by analysis of four of the original variables, taken separately, although there is significant between-provenance variation. The Rosh HaNiqra seed source tends to have more extreme component values than the others.

Liquid cultures used to scale up mass propagation often affect adversely shoot morphogenesis. Abnormal shoot morphogenesis due to continuous submergence and vigorous aeration in the liquid medium results in vitreous shoots which poorly survive transplanting ex vitro. Nephrolepis, Philodendron, and Gladiolus bud explants were cultured in liquid medium in shaken cultures or bioreactors. Ferns propagated in liquid medium in shaken cultures produced meristemoid clusters, while leafy shoots developed in agar. In bioreactors the biomass was two to three times higher than in shaken cultures. Meristemoid clusters separated and inoculated to pretransplanting hardening agar medium developed normal shoots. In Gladiolus, shoot morphogenesis was controlled by the use of growth retardants, which also enhanced bud and protocorm production.

These values were compared with the Hadas/Russo results for the same seeds. Soil density changes at the seed-soil contact interface were calculated and the approximate pressures exerted on the soil by the swelling seeds were evaluated from consolidation test data for the sand and silty soils used in the experiments. Seed diffusivity to water according to the Collis-George/Melville model was in close agreement with the Hadas/Russo data only for the later part of the imbibition process when the seeds are fully imbibed or nearly so. The non-swelling Hadas/Russo model cannot be expected to yield accurate values at low seed moisture contents. The Collis-George/Melville model failed to yield consistent values for vetch seeds due to their partially impermeable seed coat. As expected, the calculated diffusivities to water of the seeds decrease as the external potential becomes more negative. Due to soil compaction during the imbibition process, the volume of the germinating seeds was smaller than that of free-swelling seeds under the same external water potential conditions. Soil mechanical constraints and water stress caused delayed germination but did not affect final germination. Their specific effects could not be differentiated under the present experimental conditions.","PeriodicalId":196860,"journal":{"name":"Israel journal of botany","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116883301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a calcareous loess soil, additions of superphosphate equivalent to 3,000 kg ha−1 could not alleviate the absence of the VAM association. Increasing internal leaf P levels were correlated closely with a stimulation of flower bud production in pepper. Subsequent planting of onion in the same soils with no further P addition revealed the total dependency of this species on the VAM symbiosis. Mycorrhizal infection reduced by half the R/S ratios of onion plants, mainly by the enhancement of shoot growth. Results indicate the presence of a highly efficient VAM population in the loess soil. These findings are considered with regard to the evolution of the mycorrhizal association and its effect on plant morphology and physiological processes.","PeriodicalId":196860,"journal":{"name":"Israel journal of botany","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128433635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
