Like struggling swimmers trying to keep their heads above water, rosette plants lift up their leaves when faced with flooding. Instead of flailing arms and legs, plants use hyponastic petiole growth to improve their chances of keeping leaves in contact with the air. During this hyponastic growth, cells on the abaxial side of the petiole elongate more than those on the adaxial side, changing the...

As an endophytic fungus, the growth-promoting effects of Piriformospora indica have been widely confirmed in many its host plants. In this study, we investigated influences P. colonization on growth daughter plants two strawberry cultivars, ‘Benihoppe’ and ‘Sweet Charlie.’ The results showed that fungus significantly promoted both varieties. Its greatly improved almost all parameters plants, in...

Population growth and the high demand for food production has caused environmental degradation losses in biodiversity. The conservation of genetic resources is most appropriate strategy maintaining variability species great importance, such as Capsicum. In this study, we describe characterization 69 pepper accessions four Capsicum from different regions Brazil on basis qualitative quantitative ...

One of the most important pollution in world is air pollution. factors that cause this vehicles. Heavy metals have a great role component caused by vehicles and they negative effects on plant human health. In study, it was aimed to determine effect distance from highway leaf morphology anatomy economically Red Globe grape variety. Leaf samples were collected four different distances (road side,...

Vegetables have a relatively high nitrogen requirement and at times growers apply too much fertilizer-N that contributes to ground and surface water pollution. Fertilization can be made more efficient by plant analysis. Plant tissue (petiole) nitrate testing is a way of monitoring the nitrogen condition of the crop during the growing season. This is an especially useful method as the petiole is...

It has been observed in this laboratory (15) that the normally polar distribution of callus growth on tobacco stem explants becomes non-po'ar in the presence of low levels of 2,3,5-triiodobenzoic acid (TIBA), while the amount of callus growth is not diminished. It was thought that this phenomenon might reflect a specific inhibition by TIBA of the polar transport of auxin. Subsequent studies (10...
