In this chapter we describe an Agrobacterium tumefaciens transformation method of soybean that utilizes mature half seeds and regeneration from the cotyledonary node region. This method results in fertile transformed soybean plants and transgenic seed in approximately 9 months. Using mature half seeds as starting material has proven to be a reliable method that does not require additional wound...

an experiment was conducted at assossa agricultural research center (aarc) station during 2008 cropping season in order to study the effects of co-inoculation of bradyrhizobium japonicum (tal-378 and tal-379) and phosphate-solubilizing bacteria (psb) (pseudomonas spp.), and conventional farmers’ fertilizer level (combined and individual application of 46n kg ha-1 and 46 p2o5 kg ha-1) on nodulat...

Packaging types as influencing seed quality in some soybean [Glycine max (L.) Merr.] varieties during storage period | Ratna Wylis Arief, Robet Asnawi, Reny D. Tambunan, Nila Wardani, Dewi Rumbaina Mustikawati, Made Jana Mejaya Agricultural Journals

The soybean aphid, Aphis glycines Matsumura, is a new pest of soybean, Glycine max (L.) Merr., in North America. It has become widespread on soybean in North America since it was first identified in the Midwest in 2000. Species of Rhamnus L. (buckthorn) are the primary hosts of A. glycines, and soybean is known as a secondary host. There is limited information about the secondary host range of ...

and to be colonized by arbuscular mycorrhiza (AM) fungi (Harrison, 1997). Often, nodule formation by a Isoforms of endochitinase in soybean were studied in given bacterial strain is restricted to only a few host plant relation to root symbiosis. Five selected cultivars difgenera, and varieties of a given legume species may differ fering in their nodulation potential were inoculated in nodule fo...

The refractive index of soybean (Glycine max [L.] Merr.) leaf cell walls was measured by two methods. The refractive index of fully hydrated walls in the living leaf was about 1.415, while that of dried cell walls was about 1.53. The refractive index of the external surface of the living leaf hair was 1.48.

Four genotypes of soybean (Glycine max L. Merr.) were taken for investigation to know their response towards chromium stress. On the basis of seedling growth vigour index and dry weight, the genotypes JS 355 and P 1 were found tolerant to chromium stress when compared to the other genotypes. The tolerant genotypes had shown higher proline contents in their shoots.

Cytological observations were made on developing seeds of soybean (Glycine max (L.) Merr. "Amsoy 71") using scanning and transmission electron microscopy and light microscopy. Attention was focused on the maternal tissues of the seed coat and embryo sac. An hypothesis of photosynthate import, unloading, and movement to the embryo is presented based on the results of these studies.

Sulfentrazone has excellent soil activity on many small-seeded broadleaf weeds, however, soybean injury in "eld experiments has been noted under certain environmental conditions. Injury levels in these "eld experiments have appeared to di!er in severity among soybean cultivars. Growth chamber studies were initiated with the objective of examining the suspected di!erences in tolerance among soyb...
