Tradescantia pollen grains, isolated during the period of DNA synthesis in the generative cell, accumulate deoxythymidine triphosphate (dTTP)-(3)H after incubation with thymidine-(3)H in the presence of millimolar deoxyadenosine. Most of this dTTP-(3)H was found to resist extraction by the fixative, cold ethanol-acetic acid, and its location was investigated by radioautography with thin, dry em...

The article indicates morphological features of vegetative and generative buds 20 varieties highbush 3 halfhighbush blueberry. Generative are laid in the upper part branching shoots, less often on replacement shoots. Flower much larger than buds, ovoid, from 3.9 (Jersey) to 6.5 mm (Hardyblue) long, 2.0 (Herbert, Patriot) 2.7 diameter (Reka). Depending varietal specificity, average, 1.3 (Carolin...

Epichloë species (including the former genus Neotyphodium) are fungal symbionts of many agronomically important forage grasses, and provide their grass hosts with protection from a wide range of biotic and abiotic stresses. Epichloë species include many interspecific hybrids with allodiploid-like genomes, which may provide the potential for combined traits or recombination to generate new trait...

Effect of Different Substrates Containing Azolla Compost and Rice Bran on Vegetative Physiological Traits Three Pothos Cultivars

Many studies have confirmed positive effect of biochar as a soil conditioner that can increase in short time the amount organic matter (SO) and reserves carbon (OC) soil. The use also contributes to eliminating effects fatigue, especially perennial fruit crops. In our study, was applied spring 2014 cultivation one-year-old peach trees cultivar Meredith. Biochar, an fertilizer, microbiologically...

After meiosis, an unequal cell division generates the male gamete lineage in flowering plants. The generative cell will undergo a second division, giving rise to the two gametes, i.e. the sperm cells. The other cell will develop into the vegetative cell that plays a crucial role in pollen tube formation and sperm delivery. Recently, the vegetative cell has been suggested to be important for pro...

rootstock and cultivar selection is the most critical decision at the time of an apple orchard establishment. tree size, yield and fruit quality are affected by roostock and cultivar. non-sufficient study of rootstocks and cultivars effects on mentioned traits will lead to incorrect result or failure in orchard managing. in this study the effects of three vegetative rootstocks (mm106, mm111 and...

By applying multivariate statistical analysis, this research aimed to estimate the heritability and find relationships between the vegetative and reproductive characteristics of Prunus scoparia and Prunus elaeagnifolia. Twenty genotypes of each species were selected randomly from cultivated populations and twenty-two traits including the tree, leaf, flower, nut and kernel attributes were measur...
