گونه مرزه با نام علمی Satureja edmondi Briq از گیاهان دارویی مهم بهشمار میآید واز مرزههای انحصاری و نادر ایران است. از آنجایی که بذر این گیاه به اندازه کافی در طبیعت وجود ندارد و بذور موجود نیز بهسختی جوانهدار میشوند، روش ریزازدیادی جهت احیاء و تکثیر انبوه بهمنظور حفظ و جلوگیری از خطر انقراض و نیز بررسی و شناخت بیشتر این گونه در دستور کار این پژوهش قرار گرفت. بدین منظور سرشاخههای سبز گ...
حفظ ذخایر ژنتیکی و جلوگیری از فرسایش گونه های گیاهی، به ویژه گونه های بومی و در حال خطر از اهمیت ویژه ای برخوردار است. فراسرمانگاهداشت یا نگهداری دردمای نیتروژن مایع (?c196-)، کارآمدترین روش ذخیره سازی طولانی مدت منابع ژنتیکی گیاهی با حداکثر ثبات فنوتیپی و ژنوتیپی است. این تکنیک برای نگهداری بذر، جنین، جوانه و سلول های گونه بومی smirnovia turkestana مورد استفاده قرار گرفت. به منظور تولید مواد گ...
Formaldehyde and phenol biodegradation during the denitrification process was studied at lab-scale, first in anoxic batch assays and then in a continuous anoxic reactor. The biodegradation of formaldehyde (260 mgl(-1)) as single carbon source and at phenol concentrations ranging from 30 to 580 mgl(-1) was investigated in batch assays, obtaining an initial biodegradation rate around 0.5g CH(2)Og...
The present study was carried out to investigate micropropagation possibility and determine the optimal medium composition and plant growth regulators (PGRs) combinations under in vitro conditions. The cotyledon and epicotyl explants obtained from 1 month old in vitro grown seedlings were used in MS medium containing BA (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) and TDZ (0.1, 0.2, 0.5, 1, 2 and 3 mg-1) e...
The present study aimed at establishing a complete plant regeneration protocol for Didymopanax morototoni (matchwood), a native Brazilian forest species. Four types of explants (root, shoot, node, and cotyledonary leaves) were obtained from in vitro germinated seeds. In the first step, woody plant medium (WPM) with casein hydrolysate (250 mgL-1 ) and 2,4-D (1.0 and 5.0 mgL-1) were used combined...
A simple and efficient protocol for recurrent somatic embryogenesis and plant regeneration is one of the prerequisites for genetic improvement of guava. An efficient reproducible regeneration somatic embryogenesis protocol was developed in four genotypes of Psidium guajava L. using immature zygotic embryo as starter explant. Somatic embryogenesis induction was obtained on MS basal medium supple...
Endocannabinoids, particularly 2-arachidonoyl glycerol (2-AG), impact the directional turning and motility of a developing axon by activating CB(1) cannabinoid receptors (CB(1)Rs) in its growth cone. Recent findings posit that sn-1-diacylglycerol lipases (DAGLα/β) synthesize 2-AG in the motile axon segment of developing pyramidal cells. Coincident axonal targeting of CB(1)Rs and DAGLs prompts t...

Alternate bearing is a key factor in limiting citrus production. Chemical controls have proved to be the most effective solution to this problem. Two different experiments were conducted to study the effects of different growth regulators (GA3, NAA, Ethephon) and urea on alternate bearing control in Kinnow mandarin (Citrus reticulata). In the first experiment, GA3 at concentrations of 0, 25, 50...
