[ 1 ] - The Effect of CaCl2 Salinity on Growth Parameters of Lisianthus Cultivars

Soil and water salinity substantially constrain crop and biomass production. To investigate the changes in morphological parameters of lisianthus (Eustoma grandiflorum) cultivars under CaCl2 salinity conditions a greenhouse experiment was conducted. Cultivars namely, ‘Champagne’ (C1), ‘Lime Green’ (C2), ‘Blue Picotee’ (C3) and ‘Pure White’ (C4), were subjected to salt stress (0–30 mM CaCl2) in ...

[ 3 ] - بررسی تنوع ژنتیکی و وراثت‌پذیری ویژگی‌های فیزیولوژیکی و فنولوژیکی برخی ارقام و ژنوتیپ‌های زردآلو (Prunus armeniaca L.)

بررسی تنوع ژنتیکی زردآلو، موجب افزایش شناخت نسبت به این گیاه شده و امکان انتخاب ژنوتیپ‌های مرغوب‌تر را برای توسعه کشت و کار فراهم می‌نماید. در این پژوهش، تنوع ژنتیکی 26 رقم و ژنوتیپ زردآلوی موجود در کلکسیون ایستگاه تحقیقاتی کشاورزی کردستان با استفاده از ارزیابی ویژگی‌های فنولوژیکی و فیزیولوژیکی در قالب طرح بلوک‌های کامل تصادفی با سه تکرار مورد ارزیابی قرار گرفت. نتایج تجزیه واریانس داده‌ها نشان...

[ 4 ] - Effect of salinity stress on some physiological characteristics and photosynthetic parameters of several Iranian commercial pomegranate genotypes

In order to evaluate the salinity tolerance of six pomegranate genotypes including Malas Dane Ghermez Esfahan, Malas Yazdi, Shirin Shahvar, Meykhosh Yazd, Malas Saveh and Malas Yousofkhani, a greenhouse experiment was conducted as a factorial based on randomized complete block design with five salinity levels of 0, 25, 50, 75 and 100 mM sodium chloride at Agricultural College of Lorestan Univer...

[ 5 ] - The Effects of Simulated Vibration Stress on Plant Height and Some Physical and Mechanical Properties of Coleus blumei Benth

Non-chemical control of plant growth is an important goal for the production of ornamental pot plants. In the present study the effects of simulated vibration on plant height and some physical and mechanical properties of Coleus stem were investigated. The study was conducted as a factorial experiment based on a completely randomized design with three replications. Vibration stresses were perfo...

[ 6 ] - Evaluation of Physiological Responses of Tuberose (Polianthes tuberosa L.) to Water Deficit Stress

Water stress is one of the main factors of severe damage and limitation of plant production in Iran. The paper reports a pot experiment conducted by using a factorial experiment based on a completely randomized design with three replications (each replication composed of four pots) to compare the physiological and biochemical characteristics of two varieties of tuberose (double- and single-flow...

[ 7 ] - Effects of ascorbic acid on physiological and biochemical responses of Zinnia elegans L. to different levels of light intensity

The aim of this study was to investigate the effect of different light intensities and ascorbic acid on some physiological and biochemical characteristics of Zinnia elegans L. The experiment was designed as a completely randomized design in a form of split-plot with three replications. The treatments were consisted of three light intensity levels (600, 1200 and 1800 μmol m-2 s-1) as the main fa...
