The experiment was conducted at the Agronomy field of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during August, 2008 to January 2009 to find out the optimum plant spacing and number of seedling per hill in relation to tillering and dry matter accumulation of transplanted rice plant. The experiment was carried out with three plant spacings (S =15 cm × 20 cm, S = 20 cm × 20 cm and S...

Ganoderma boninense is the basal stem rot disease (BSR) pathogen that devastates oil palm plantations. Disease infection generally occurs by a single strain of G. boninense, or co-infection two strains arises as revealed somatic incompatibility. This study aimed to determine effects somatically incompatible on BSR seedlings. Two were from 2 plantations and had different aggressiveness. Co-infec...

The activity of guanylyl cyclase (GC) responsible for cGMP synthesis was found to be predominantly located in a fraction of plasma membranes in cells of Avena sativa seedlings. The GC activity was shown to depend on light conditions of plant cultivation and seedlings age. The reversible regulation of the GC activity in etiolated seedlings by red/far red light was found. This suggests that photo...

Limitations of cuttings become an essential problem in the expansion cassava plantations. One strategy that can be taken is to reduce length and increase plant population area planted produce more stems per unit for next growing season. This study aimed determine effect cutting hectare on growth production stems. The research was carried out at Jambegede Agricultural Technology Research Assessm...

The integrity of forest stands in logging concessions depends on the method. Selective is most commonly used method tropics, disturbing a considerable proportion soil and canopy cover creating distinct sites for plant establishment. objective this study was to evaluate silvicultural requirements terms light moisture seedlings some commercial tree species enrichment planting. This carried out tw...

A previously unreported bacterial disease on chili pepper (Capsicum annuum L.) seedlings affecting as many as 4% of seedlings was observed in greenhouses in Chihuahua, Mexico (Delicias and Meoqui counties). Initial lesions appeared as irregular small spots on leaves and brown necrosis at margins tips were observed. Later, the spots became necrotic with a chlorotic halo. Advanced disease was ass...

The forest-savanna ecotone may be very sharp in fire-prone areas. Fire and competition for light play key roles in its maintenance, as forest and savanna tree seedlings are quickly excluded from the other ecosystem. We hypothesized a tradeoff between seedling traits linked to fire resistance and to competition for light to explain these exclusions. We compared growth- and survival-related trait...

Aldehyde oxidase (AO; EC 1.2.3.1) activity was measured in seedlings of wild type or an auxin-overproducing mutant, superroot1 (sur1), of Arabidopsis thaliana. Activity staining for AO after native polyacrylamide gel electrophoresis separation of seedling extracts revealed that there were three major bands with AO activity (AO1-3) in wild-type and mutant seedlings. One of them (AO1) had a highe...
