Correlation coefficient and path analysis studies was conducted with eight parents and their 28 F1 crosses for twelve component characters including seed yield and revealed significant positive association of pods per plant, harvest index and clusters per plant with seed yield in parental generation whereas in F1 generation, significant positive association of clusters per plant, pods per plant...

In contrast to wild-type seeds of Arabidopsis thaliana and to seeds deficient in (aba) or insensitive to (abi3) abscisic acid (ABA), maturing seeds of recombinant (aba,abi3) plants fail to desiccate, remain green, and lose viability upon drying. These double-mutant seeds acquire only low levels of the major storage proteins and are deficient in several low mol wt polypeptides, both soluble and ...

Ageing induces seed deterioration expressed as the loss of seed vigor and/or viability. Priming treatment, which consists in soaking of seeds in a solution of low water potential, has been shown to reinvigorate aged seeds. An experiment was conducted to evaluate the effects of naturally and accelerated aging on seed germination traits and enzyme activities (proxidase, catalase and superoxid dis...

The high cost of treated water makes most people in the rural communities to resort to readily available water sources which are normally of low quality exposing them to waterborne diseases. The present study was carried out to confirm the effectiveness of seed powder extracted from mature-dried Moringa oleifera seeds which are commonly available in most rural communities. The main objective of...

BACKGROUND Some neotropical, fleshy-fruited plants have fruits structurally similar to paleotropical fruits dispersed by megafauna (mammals > 10(3) kg), yet these dispersers were extinct in South America 10-15 Kyr BP. Anachronic dispersal systems are best explained by interactions with extinct animals and show impaired dispersal resulting in altered seed dispersal dynamics. METHODOLOGY/PRINCI...

this research evaluated the effects of gibberellin (ga3) and abscisic acid (aba) on emergence capability, rate of emergence, vigor index and some physiological characters of chickpea seedling (cicer arietinum l.) in a field experiment (as split) under dry and irrigated conditions. seeds were primed with 0, 50, 100 and 150 ppm of each phytohormones. examined chickpea cultivar was azad. the resul...

Three faba bean (Vicia faba L.) cross populations, i.e. Giza 40/Giza 3 (Cross No.1), Slaim/Giza 3 (Cross No.2) and Slaim/311/1170/81 (Cross No.3), were made for selection by three methods, i.e. Mass selection (MSM), pedigree selection (PSM) and Picking-pod (PPM) from F to F generation during 2005/2006, 2006/2007 and 2 4 2007/2008 seasons at Mattana Agricultural Research Station, ARC, Isna, Qena...

Tocopherols and tocotrienols are present in mature seeds. Yet, little is known about the physiological role and the metabolism of these compounds during seed development. Here we present data on tocopherol and tocotrienol accumulation during seed development in Vitis vinifera L. cv. Albert Lavallée (Royal). This species was chosen for its ability to synthesize both tocopherols and tocotrienols....

Round seeds are desirable for food-type soybean [Glycine max (L.) Merr.], and the genetic control of seed geometry is of scientific interest. The aim of this research was to: (1) compare the seed shape variation of 165 soybean cultivars and to quantify the characteristics of the cultivars, and, (2) to evaluate the seed shape of the parental F1 and F2 populations derived from Tamahomare × Peking...
