PREMISE OF THE STUDY Mammalian herbivores, particularly white-tailed deer, can have a major impact on plant abundance and distribution. However, plants can tolerate herbivory by increasing seed production or seed quality. We used the monocarpic perennial Prenanthes roanensis to examine tolerance to mammalian herbivory through seed quality and modeled the effects of tolerance on population growt...

Abstract The value of seed depends on its quality. Hence, evaluation quality is critical in any production system. It is, therefore, desired that tested for all essential parameters, following the standard procedures and performing tests such a manner results are consistent reproducible, within permissible limits tolerance. As submitted sample only minute fraction whole lot, reproducibility rel...

The effect of row spacings and irrigation levels on the earliness of seed production of cotton was investigated under the Mediterranean environment of central Greece. This particular cotton growing area is exposed to risk of autumn rainfall that might cause low seed quality in fields allocated primarily for seed production. Two varieties of cotton, Celia and Hersi, were planted in two row spaci...

Production of high quality seeds is of fundamental importance for successful crop production. However, knowledge of the effects of increased temperature resulting from global warming on seed quality of alpine species is limited. We investigated the effect of maternal environment on seed quality of three cultivars of the leguminous forage species Vicia sativa, giving particular attention to temp...

Entity Set Expansion is an important task for open information extraction, which refers to expanding a given partial seed set to a more complete set that belongs to the same semantic class. Many previous researches have proved that the quality of seeds can influence expansion performance a lot since human-input seeds may be ambiguous, sparse etc. In this paper, we propose a novel method which c...

DOR: 98.1000/2383-1251.1398.6.51.11.1. 1575.1578 Extended Abstract Introduction: Pulses are a group of crops which are important in human nutrition and also sustainability of agronomical systems and economic advantage. Regarding optimum planting density of mung beans (40 plant m-2), more than 700 tons of certified seeds of mung bean seeds are needed all over the country, confirming the im...

Heat damage to seed can occur as a result of the cumulative effects of respiration and fungal heating, and by the accumulation and retention of radiant heat within the seed mass following harvest both situations being collectively referred to as ‘field heating’. Another type of heating damage occurs in heated air drying systems. Excessive drying air temperature can have deleterious effects on s...

Extended Abstract Introduction: Structural and physiological delicacy of soybean seeds is known as an important quality indicator in the cultivation of this plant, but at the same time, the most chronic problems of soybean seed quality are the reduction of seed quality during storage and before sowing. The effect of some nutrients on the quality of soybean seeds under accelerated aging stress ...

A cornerstone of upgrading productivity of tilapia culture is the continuous improvement in the quality of seed used by farmers. This statement is relevant to the spectrum of tilapia production systems, but ‘quality’ is subjective and requires to be defined for specific contexts. An overview of strategies to improve the quality of seed under different conditions is presented. Consumer, marketin...
