| چکیده | ||
| بروز تنش خشکی روی گیاه مادری میتواند سبب کاهش جوانهزنی و رشد بذور گیاهان تحت این شرایط شود. از سوی دیگر استفاده از ترکیبات زیستی در تنشهای محیطی سبب تولید بذور با قابلیت جوانهزنی بهتر میشود. این پژوهش به صورت اسپلیت پلات در قالب طرح بلوکهای کامل تصادفی با سه تکرار در سال 1395 انجام گردید. عامل اصلی شامل رژیمهای مختلف آبیاری در سه سطح آبیاری پس از 25، 50 و 75 درصد تخلیه رطوبتی خاک و عامل فرعی شامل تأمین نیاز فسفر در شش سطح 100 درصد نیاز فسفر به صورت شیمیایی از منبع سوپرفسفات تریپل، 50 درصد فسفر + قارچ مایکوریزا آربوسکولار، قارچ مایکوریزا آربوسکولار، 50 درصد فسفر + باکتری سودوموناس فلورسنس، باکتری سودوموناس فلورسنس و شاهد بدون کود فسفره بود. نتایج نشان داد که در رژیم آبیاری 75 درصد تخلیه رطوبتی، حداکثر جوانهزنی، بنیه بذر، طول ریشهچه، طول ساقهچه و وزن خشک گیاهچه در 50 درصد نیاز فسفر + مایکوریزا آربوسکولار بود. همچنین در سطح آبیاری پس از 50 و 75 درصد تخلیه رطوبتی، تیمار 50 درصد نیاز فسفر + مایکوریزا آربوسکولار توانست سبب افزایش سرعت جوانهزنی و بهبود یکنواختی جوانهزنی شود. هدایت الکتریکی بذرهای سرخارگل با افزایش تنش خشکی روند افزایشی را نشان داد. در مجموع نتایج این پژوهش نشان داد که باکتری سودوموناس فلورسنس در این آزمایش در سطح پایینتر از قارچ مایکوریزا آربوسکولار توانست درصد و سرعت جوانهزنی و اثرات منفی ناشی از تنش خشکی را بهبود دهد. | ||

| چکیده [English] | ||
| Reduction in germination and growth can be seen in seeds obtained from mother plants which have experienced water stress. From the other point of view utilization of biological fertilizers under environmental stress, the condition can produce seeds with higher germination capacity. This research was conducted as split plot based on a randomized complete block design with three replications in 2016. The main factor included of irrigation regimes at three levels included in soil irrigation after 25, 50 and 75% of soil moisture depletion and a sub-factor of phosphorus supply in six levels included of 100% phosphorus requirement from the source of triple superphosphate, 50% phosphorus + arbuscular mycorrhizal fungus, Mycorrhiza arbuscular fungus, 50% phosphorus + Pseudomonas fluorescens, Pseudomonas fluorescens and a control test without phosphorus fertilizer. Results showed that in 75% of soil moisture depletion, maximum amounts of germination, seed vigor, root length, stem length and seedling dry weight were obtained from 50% of phosphorus + arbuscular mycorrhiza. At irrigation level of 50 and 75% moisture depletion, the application of 50% phosphorus + arbuscular mycorrhiza made an increase in germination rate and uniformity. The electrical conductivity of Echinacea purpurea seeds showed increasing trend with intensification in drought stress. The results of this study showed that in present study Pseudomonas fluorescens had lower improvement effects on percent and rate of germination and the adjustment of drought adverse effects in compared with arbuscular mycorrhiza. | ||
