Growth and mineral distribution in grafted tomato/potato plants according to sink number     

G. Bünemann  A. Grassia 《Scientia Horticulturae》1973,1(1):13-24

Graft combinations of potato and tomato were cultivated to study the dry matter and mineral nutrient distribution in plants with and without one or two storage organs. N and P entered the fruits and tubers in an order of magnitude roughly comparable to dry matter distribution; K entered them even more liberally than would correspond to their relative dry matter content, whereas Ca and Mg showed a distribution pattern completely different from that of dry matter or N, P and K. Obviously, it is very difficult to bring sizeable quantities of Ca and Mg into fruits and tubers. This observation is discussed with reference to the prevention of so-called calcium and magnesium deficiency disorders in fruits and with regard to possible changes in leaf analysis values obtained for some of the major nutrients.  相似文献   

Enumeration of rhizobia from a plant-infection dilution assay using test plants grown in vermiculite     

A. Grassia  J. Brockwell 《Soil biology & biochemistry》1978,10(2):101-104

A procedure is discussed for the estimation of bacterial numbers using plant-infection assays in which the probability of bacteria reaching and infecting the test plants is not fixed but follows a probability distribution. Application of the procedure to counting populations of Rhizobium spp. is considered.  相似文献

Senatore F  Rigano D  Formisano C  Grassia A  Basile A  Sorbo S 《Fitoterapia》2007,78(3):244-247

The methanolic extract of Verbascum sinuatum inflorescences and isolated compounds were tested for their antibacterial activity against 13 Gram(+) and Gram(-) bacteria and for their allelopathic activity against radish.  相似文献   

The relationship of inoculum density of Phytophthora cinnamomi chlamydospores in soil and infection of Eucalyptus marginata seedlings     

A. Grassia  D.D. Darling  J.F. Titze 《Soil biology & biochemistry》1984,16(3):269-271

Chlamydospores of Phytophthora cinnamomi were used as inoculum of known density (ID) in an investigation of the rate of jarrah seed germination and the level of infection of seedlings at the various ID's.Inoculum recovery by soil plating was about 2% of the added density. The germination of the jarrah seedlings was accelerated by the increase of the ID, especially at ID of 250 chlamydospores g^?1 soil. The nominal LD₅₀ value for jarrah seedlings per chlamydospore inoculum was calculated as 13.0 chlamydospores g^?1 soil and the number of viable chlamydospores in the rhizosphere at the highest ID was estimated as 9.1.  相似文献   

Antibacterial and allelopathic activity of methanolic extract from Iris pseudopumila rhizomes     

Rigano D  Grassia A  Formisano C  Basile A  Sorbo S  Senatore F 《Fitoterapia》2006,77(6):460-462

The methanolic extract of rhizomes of Iris pseudopumila was tested for its antibacterial and allelopathic activity. The extract was shown to have antibacterial effects. The allelopathic effect was tested against Raphanus sativus seed germination. The extract caused a decrease in the percentage of seed germination and root and epicotyl growth.  相似文献
