This study aimed to investigate effect of different organic supplements on growth of Vanda and Mokara seedlings. Vanda and Mokara seedlings approximately 0.2 and 0.3 cm. in height were sub-cultured onto VW supplemented with 150 ml/L coconut water, 100 g/L potato extract, 100 g/L ‘Gros Michel’ banana (AAA group) and 100 g/L ‘Namwa’ banana (ABB group). The explants were sub-cultured onto the same...

Prolyl 4-hydroxylases (P4Hs) belong to the family of 2-oxoglutarate-dependent dioxygenases and catalyze the formation of 4-hydroxyproline, requiring 2-oxoglutarate and O2 as co-substrates and Fe as a co-factor. Nine putative P4Hs have been identified up to now in the tomato genome. A reverse genetics approach, Virus-Induced Gene Silencing, was used to silence two P4Hs, P4H3 and P4H8. Transient ...

micropropagation is a proper approach to rapid and large-scale propagation of rootstocks and rose cultivars for huge demand of flower market. proliferation rate of shoot is decreased drastically following several subcultures. growth regulators have remarkable effects on the key phase of proliferation in micropropagation of this popular crop. in this research the effects of bap and antiauxin of ...

environmental stress, particularly drought stress can play an important role in reducing plant growth especially during the germination stage in arid and semi-arid regions in iran. for cultivation of medicinal plants in arid and semi-arid areas, the assessment of their tolerance is very important. in this research, in order to evaluate the effects of salicylic acid pretreatment on enhancement o...

the aim of this study was to identify the effect of spermine and salicylic acid on several growth parameters, such as shoot length, shoot fresh and dry weights, amount of protein and carbohydrate, of badami and qazvini pistachio cultivated variety under copper stress. the experiment design was completely randomized with three replicates per treatment and four levels of copper (o.5, 30, 45, 60 µ...

Pistacia vera cv Badami-e-riz and P.vera cv Ghazvini are the most important and popular rootstocks in Iran, which tolerate salinity and phytophthora fungi. This study was conducted to evaluate the effects of various concentrations of polyamines and IBA on root regeneration of transplanted bare- rooted ‘Badami-e-riz’ and ‘Ghazvini’ pistachio rootstocks. The mean comparison between IBA and polyam...
