The composition of the translocates reaching the seeds of pea plants having various nitrogen (N) nutrition regimes was investigated under field situations. Sucrose flow in the phloem sap increased with the node number, but was not significantly different between N nutrition levels. Because N deficiency reduced the number of flowering nodes and the number of seeds per pod, the sucrose flow bleed...

To further elucidate the regulation of dormancy release, we followed the natural afterripening of Virginia-type peanut (Arachis hypogaea L.) seeds from about the 5th to 40th week after harvest. Seeds were kept at low temperature (3 +/- 2 C) until just prior to testing for germination, ethylene production, and internal ethylene concentration. Germination tended to fluctuate but did not increase ...

effects of five seeding rates (350, 425, 500, 575 and 650 seeds per m2) on four wheat cultivars (kavir, mahdavi, shiraz and roshan) were studied under salinity stress, during 2000-2001 crop seasons in roodasht agricultural research station, esfahan. a factorial experiment based on randomized complete block design with three replications was used. plants were irrigated with saline water (with ec...

inheritance of yield and its contributing characters in rapeseed (brassica napus l.) was studied in a 8×8 diallel cross through griffing and jinks-hayman analyses. both general combining ability (gca) and specific combining ability (sca) were highly significant for seed yield, seed weight and branches per plant, while only gca for seeds per pod and oil content and only sca for pods per plant an...

Article info: Received: 30 April 2014 Accepted: 29 January 2015 ABSTRACT The trial was carried during 2011-2013 on the second experimental field of the Institute of Forage Crops – Pleven, Bulgaria. Eight generations (P1, P2, F1, F2, RC1 and each reciprocal generation) from a cross between the Shtambovii and Pleven 10 varieties were sown in this study. Five traits were evaluated: number of pods ...

Developing Berberis hispanica Boiss & Reuter berries are heavily attacked by a single species of fly larvae which feed on seed contents. There is a steady increase in fruit attack incidence with increasing number of seeds in the fruit, and individual developing seeds have a greater average probability of escaping predation when single in fruits (0.688) than when two (0.379) or more (0.120) are ...

We studied the life history, geographic distribution, behavior, and ecology of Larinus filiformis Petri (Coleoptera: Curculionidae) in its native range to determine whether it is worthy of further evaluation as a classical biological control agent of yellow starthistle, Centaurea solstitialis (Asteraceae: Cardueae). Larinus filiformis occurs in Armenia, Azerbaijan, Turkey, and Bulgaria and has ...

In Iran, more than 90% of raw materials including oils and oil seeds are provided through import. Camelina sativa L. as an oilseed crop, belongs to Brassicaceae family, has been shown in several experiments that need very little water and resistant to chilling injury than other plant oils, especially canola. This Experiment was conducted at research station of Campus of Agriculture and Natural ...

this study was conducted to evaluate the effect of foliar micronutrients cu, mg and b on quantitative traits in two sesame crop year 1394 was performed farmer field. a split plot experiment in randomized complete block design with three replications. the main factor includes four operating cu sulfate solution, mg sulfate, b sulfate and control (water) and subplots consisted of two sesame (uniqu...
