Seed germination and seedling growth performance of Maesopsis eminii Terminalia catappa under different water soaking treatments were evaluated for 120 days nursery conditions. A total 1400 seeds pre-treated with hot (95oC) cold (ambient temperature) by 12, 24 48 hours a control no soaking. The sown directly into polythene pots filled uniform medium (top forest soil, sand clay soilmixed in rati...

Daily counts of germinated seeds of white saxaul (Haloxylon persicum) incubated at 35 different hydrothermal environments (10-25?C and 0 to -3 MPa) were carried out under controlled laboratory conditions. The seeds were then buried in sand at 4 different depths in well drained pots constantly moisturized for three weeks. In all these hydrothermal conditions, the courses of germination were comp...

During last two decades studies on endozoochorous seed dispersal indicated that a large numbers of plant seeds are potentially dispersed and suceefully germinated via animal dung. However, very little is known about the relative importance of endozoochory in germination success of plant species in semi-steppe rangelands. In this paper we examined dung germinating seed content, seed deposition p...

dormancy breaking and germination requirements were investigated in seeds of ferula ovina and ferula gummosa. seeds of rather species were collected from north and eastern-north rangelands of iran. seeds of each of the species were subjected to different treatments including various levels of ga3, chilling and combination of ga3 and chilling (ga-chilling). in contrast to treated seeds, non-trea...

than those for 100 % curves. Since there exists no non-decreasing functional relationship between germination percentage and energy loss in this region, ionizations in the fruit coat cannot be responsible for the induced germination. Likewise, in the region of the embryo there is a 69 % germination curve which lies above a 100 % curve. (In both of these cases visible embryo damage could be seen...

The raffinose family oligosaccharides (RFOs) are a group of soluble galactosyl derivatives which include raffinose and stachyose thought to play a number of roles in plant development. They are providing a source of rapidly metabolizable carbohydrate during germination. In contrast to their potential for promoting germination, RFOs represent anti-nutritional units for monogastric animals when c...

abstract there is a world-wide effort to reduce the amount of chemicals used in crop production by introducing modern biological and ecological methods. one possible alternative is allelopathy. a laboratory trial was carried out to investigate of alleopathic potential of angelica . in this study the effect of different concentrations of aqueous extract of angelica herb was investigated on seed ...

Calotropis proceran (Asclepidaceae) is an evergreen plant and widely distributed in Hormozgan province. This plant has the allelopathic properties including germination inhibition, plumule and radicle growth reduction. In this study the effect of different concentrations (0, 5, 10, 20, 40 and 60%) of dry leaf water extraction of this plant on the germination of cucumber (Cucumis sativus), tomat...

Legumes are important sources of protein, carbohydrates, dietary fibre and minerals consumed worldwide. They are well adapted to a wide range of environmental conditions. However, only few have been promoted and extensively used. The Dolichos lablab bean is one of the lesser known legumes of arid and semi-arid regions. Nonetheless, it has been classified as a potential source of protein and mig...
