To test factors limiting regeneration of large-seeded hardwoods in the Upper Coastal Plain of South Carolina, we planted one-year old bare root Quercus alba L. and Cornus florida L. seedlings in pine plantation understories and adjacent clearcuts. We hypothesized that soil moisture, light, and leaf and stem herbivory would have relatively strong effects on growth and survival during the first t...

carbohydrate flow between vegetative and reproductive parts of trees is one of the determining factors of yield and fruit quality. therefore, it varies during different times of growth season. the aim of this study was to investigate the carbohydrate content variation during growth season between leaf and fruit of nectarine. so, eight nectarine trees cv. red gold selected randomly in the orchar...

Aquilegia `Rose-White' flowered from seed in about five months without vernalization. GA4/7 treatment increased stem height, induced earlier flowering, and increased the number of flowers/ plant. Each of these responses, however, was dependent upon both rate (10, 25, or 50 ppm) and timing of application (4-, 8-, or 12-leaf stage). Treatment at the 4-leaf stage resulted in earlier flowering at a...

Ewel, J., Gliessman, S., Amador, M., Benedict, F., Berish, C., BermfJdez, R., Brown, B., Martfnez, A., Miranda, R. and Price, N., 1982. Leaf area, light transmission, roots and leaf damage in nine tropical plant communities. Agro-Ecosystems, 7: 305--326. The vertical distribution of leaf area by species; transmission of photosynthetically active radiation; root biomass and fine-root surface are...

Corn flea beetles, Chaetocnema pulicaria, vector Erwinia stewartii (synamorph Pantoea stewartii), which causes Stewart’s bacterial wilt of corn (Zea mays) (10,11). Flea beetles introduce E. stewartii into plant tissues that are wounded during feeding. Movement of E. stewartii in the vascular system of resistant plants is restricted to within a few centimeters of flea beetle feeding wounds. The ...

conclusions regular resistance training and prostatic massage can improve proinflammatory markers and psa levels in men with pc. results in the resistance training group, il-10 levels significantly increased after four (p = 0.055) and eight weeks (p = 0.000). four and eight weeks of resistance training showed a significant reduction in psa, crp, il-6, and tnf-α levels (p < 0.05). patients of ma...

The effects of flurprimidol and paclobutrazol, treatments as preplant bulb soaks on plant height, growth parameters other properties Narcissus tazetta L. grown in pots were investigated. Bulbs soaked at 0, 10, 20 mg L-1 or paclobutrazol 100, 200 before planting. gibberellin inhibitors the flower number, flowering time, life, leaf length quantitative measurements (specific area, area ratio, thic...
