ABSTRACT
Spore germination and the development of the mature prothallia of Thelypteris rhachiflexuosa Riba follow the general pattern described elsewhere for other species of the genus; the germination is ofVittaria-type and the development of prothallia is of Drynaria-type. There is an early differentiation of short unicellular glandular hairs on margins and surfaces of the lamina. The opening of the antheridia is accomplished by separation of the whole cap cell. Archegonia have a neck with four rows of cells and in one archegonium five rows instead of four were seen. No sporophytes were observed after 100 days in culture.

    The development of the gametophytes of Thelypteris patens (Swartz) Small and Thelypteris puberula (Baker) Morton var. puberula is described in this paper. In both species the laminar, bidimensional stage follows a brief filamentous stage, which has a few cells. The adult prothallia are reniform...

    Background: Low phytoavailability of phosphorus (P) limits crop production worldwide. Increasing seed P content can improve plant establishment and increase yields. This is thought to be a consequence of faster initial root growth, which gives seedlings earlier access to growth-limiting...

    Seeds of Heliconia bihai L., H. collinsiana Griggs, H. latispatha Bentham and H. psittacorum L. f. were scarified using three methods: seed coat removal, operculum removal, and extraction of the embryo to be germinated in vitro afterwards. The three scarification methods increased the...

    A highly efficient technique of embryo rescue is critical when using stenospermocarpic Vitis vinifera cultivars (female parents) to breed novel, disease-resistant, seedless grape cultivars by hybridizing with wild Chinese Vitis species (male parents) having many disease-resistance alleles. The...
