  پیش زمینه و اهداف: Thymus vulgaris L. وT.daenensiscelakدو گونه دارویی چندساله متعلق به خانواده نعناعیان می باشند. هدف این تحقیق مطالعه اثرات پرایمینگ بذور دو گونه آویشن  Thymus vulgaris L. وT.daenensiscelakتحت تنش اشعه فرابنفش با سالیسیلیک اسید، جیبرلیک اسید و ایندول استیک اسید در شرایط آزمایشگاهی و مزرعه ای بود. شرایط آزمایشی: بذور تحت تیمار با هورمون‌های گیاهی با دوزهای 200، 400 و 600 ppmو اشعه فرابنفش با 220 گاماسل و شدت 3 kGy در سه زمان 10، 20 و 30 دقیقه قرار گرفتند. طرح آزمایشی در آزمایشگاه به صورت کاملاً تصادفی به صورت فاکتوریل و در مزرعه به صورت کاملاً تصادفی با سه تکرار انجام شد. صفات مورد برآورد در آزمایشگاه شامل درصد جوانه­زنی، متوسط زمان جوانه­زنی، طول ریشه­چه و ساقه­چه و در شرایط مزرعه تعداد برگ، ارتفاع گیاه، وزن خشک ریشه و اندام هوایی و میزان اسانس بود. نتایج و بحث:نتایج در تمامی گیاهان نشاندهنده آن بود که در شرایط آزمایشگاه، سالیسیلیک اسید بهتر از سایر تیمارها بود و تفاوت معنی‌داری در مورد اثرات جیبرلیک اسید و ایندول استیک اسید، دیده نشد. بیشترین اثرات مخرب و بهترین اثرات مفیدبه ترتیب بواسطه تابش اشعه فرابنفش به مدت 30 دقیقه و هورمون سالیسیلیک اسید با غلظت 200 و 400 ppm بدست آمد. اثرات کاربرد هورمون‌ها توسط رشد و عملکرد گیاهان در دو سال متمادی تعیین شد. وزن خشک اندام هوایی در هر دو سال بواسطه کاربرد سالیسیلیک اسید افزایش یافت اما ایندول استیک اسید و جیبرلیک اسید تأثیر سودمندی بر بذور تحت تنش اشعه فرابنفش نداشتند. توصیه کاربردی/ صنعتی: پرایمینگ با سالیسیلیک اسید بر خلاف ایندول استیک اسید و جیبرلیک اسید، منجر به محافظت بذور تحت تنش اشعه فرابنفش می شود. نتایج این تحقیق نشاندهنده آنست که افزایش سالیسیلیک اسید در گیاهان، چه به صورت کاربرد خارجی چه به صورت طبیعی منجر به تحمل به تنش های غیرزنده می شود.

  Tissue culture is an attractive alternative for plant propagation. Micropropagation is a technique to ensure a constant and uniform source of ornamental plants. Matthiola incana is an important ornamental species mainly cultivate by seed. Matthiola incana seeds were germinated on solid MS medium without plant growth regulators. Shoot proliferation and root formation are possible using kinetin (Kn) and naphthalene acetic acid (NAA). Shoot tips and leaf micro-cuttings derived from in vitro germinated seedlings were subcultured on solid MS medium containing Kn (0, 0.5, 1 and 2 mg l-1) and NAA (0, 0.5, 1 and 2 mg l-1) for shoot tips explants and Kn (0, 0.5 and 1 mg l-1) and NAA (0, 0.5 and 1 mg l-1) for leaf explants. Shoot tips media supplemented with 2 mg l-1 Kn without NAA and 2 mg l-1 NAA without Kn resulted in the best shoot length (1.20 cm) and root number (1.90), respectively. The callus was induced from most leaf media after four weeks of culture. MS mediums containing 0.5 mg l-1 Kn and 0.5 mg l-1. The largest number (1.94) and the highest length (16.60 mm) of roots were obtained in MS medium supplemented with 1 mg l-1 Kn+0.5 mg l-1 NAA. NAA prevented root formation originated from callus with concentration of 1 mg l-1+0.5 and 1 mg l-1 Kn. Manuscript profile

  To investigate the effect of different types and amounts of jasmines on the quantitative and qualitative characteristics of two strawberry cultivars, a factorial experiment was conducted in a completely randomized design in Sadra Hydroponic Greenhouse of Shiraz University in 2018. Experimental treatments include two types of jasmonate (jasmonic acid and methyl jasmonate) each in five concentrations (0, 0.5, 1, 1.5, and 2 mM) and (0, 0.25, 0.5, 1, and 1.5 mM) with four replications and three pots in each replication and two strawberry cultivars (Selva and Parus). Analysis of variance showed that the effect of experimental treatments on all studied traits except fruit weight and vitamin C was significant. The results showed that foliar application of jasmonate reduced chlorophyll content and leaf dry weight in both strawberry cultivars, while the highest number of fruits in Selva cultivar was obtained by foliar application of 2 mM jasmonic acid. The results also showed that increasing the concentration of jasmonates by reducing the total acidity and increasing fruit anthocyanins in both cultivars, improved the quality properties of strawberries. In general, Selva cultivar is more effective than jasmonate by producing soluble solids and the ratio of soluble solids to total acidity is more significant and the amount of total acidity is lower than Parus cultivar, it is more desirable in terms of quality.

  This study was conducted to evaluate the effect of auxin and cytokinin spraying in different growth stages on grain composition of maize (KSC 704) under drought stress condition during 2013 growing season at Seed and Plant Improvement Institute, Karaj, Iran. The experiment was carried out in three separate environments included non-drought stress environment, drought stress in the vegetative stage and drought stress in the reproductive stage. In each environment, foliar application of cytokinin in three stages (control, V5 –V6 and V8-V10) and foliar application of auxin in three stages (control, silk emergence and 15 days after that) was laid out as a factorial design based on randomized complete block design with three replications. The results showed that the maximum protein (10.93%) and soluble sugar (5.80%) in grain were obtained under drought stress in the productive stage whereas the maximum starch (77.37%) and grain dry mater (90.83%) were obtained in non-stress condition. Foliar application of cytokinin in V8-V10 stage, increased convert starch to soluble sugar on the other hand, foliar application of auxin in silk emergence stage caused converting hexose sugars to starch, increasing the sink capacity (grain endosperm) for receiving more starch and also increasing the grain dry mater .
