Mung bean is one of tropical and semitropical pulses that is important in food, fodder, green manure and improves soil fertility and is a cheap source of protein in human direct consumption. The use of zeolite in soils with heavy texture, because it keeps moisture and nutrients around the seeds and roots is very important. On the other hand, the application of techniques of improving seed quali...

  A factorial experiment, based on RCB design, with three replications was conducted to evaluate the effects of rhizobial inoculation, urea, and weeds on soybean performance in the field. The factors under study consisted of inoculation and non-inoculation, three levels of 0, 150, and 300 kg/ha urea, and weed-control and weed-infestation. Results showed that weed-control, inoculation and urea a...

The effect of seed mass on germination and growth was tested in fresh-seeds of Blutaparon portulacoides, Panicum racemosum, and Spartina ciliata, selected at random in southern Brazilian populations. The seed mass varied within a population of the three species. Both B. portulacoides and P. racemosum showed normal frequency distribution of seed mass, while S. ciliata did not. Significant differ...

Seed aging increases activity of reactive oxygen molecules and antioxidant enzymes have a key role against increased oxidative stress which is caused by free radicals. Effect of seed priming on increasing of these enzymes activity and its impacts on seed germination characteristics of deteriorated milk thistle seeds was studied in University of Mohaghegh Ardabili in 2013. Factoral experiment ba...

  In order to study different methods of separating the seeds of cantaloupe (Cucumis melo L. var. reticualus) from the sorrounding fleshy tissues (placenta) and the effects of various treatments on seed germination characteristics, an experiment was conducted in Agricultural and Natural Research Center of Varamin, Iran, in 2009. In this research, which was based on a randomized complete blocks ...

Relationships between respiration rate and adenylate and carbohydrate pools of the soybean (Glycine max L. Merrill) fruit during rapid seed growth were evaluated. Plants at mid pod-fill were subjected to different concentrations of CO(2) to alter the amount of photosynthate produced and, thus, available to the fruit. Respiration rate of the intact fruits was measured, along with glucose, sucros...

The relative contributions of primary and secondary seed dispersal to plant demography have received little investigation. Evidence on these seed dispersal types, on seed fate and seedling recruitment of the tropical rain forest tree Dipteryx oleifera, is presented. The study was conducted in a 6.37ha permanent plot where seeds and seedlings were located and tagged for the 2007 cohort. A total ...

Mixed intercropping of barley (Hordeum vulgare L.) with faba bean (Vicia faba L.) was compared with sole cropping for three growing seasons 2001–2003) at Holetta Agricultural Research Centre, in the central highlands of Ethiopia. The treatments were sole barley (125 kg ha−1), sole aba bean (200 kg ha−1) and an additive series of 12.5, 25, 37.5, 50 and 62.5% of the sole seed rate of faba bean mi...
