Abstract This study was carried out in the Plant Tissue Culture Laboratory of College Agriculture - Karbala Unaiversity for period from 2022 to 2023. The included use explants and different combinations sterilization, initiation multiplication vegetative shoots Stevia plantiv vitro , three phases: first sterilization (shoot tips lateral buds) using sodium hypochlorite at concentrations (0, 0.5,...

In order to improve the resistance of apples stresses (abiotic stresses) during hot and dry summers enhance their productivity marketability, Anna apple trees were treated with aminoethoxyvinylglycine (AVG), 1-methlcyclopropene (1-MCP), naphthalene acetic acid (NAA), alone, or in combination, two successive seasons. All treatments significantly increased yield per tree, average fruit volume, di...

N-acetylaspartate (NAA) quantification by 1H-magnetic resonance spectroscopy has been commonly used to assess in vivo neuronal loss in neurodegenerative disorders. Here. the authors used ex vivo and in vivo 1H-magnetic resonance spectroscopy in rat and primate models of progressive striatal degeneration induced by the mitochondrial toxin 3-nitropropionate (3NP) to determine whether early NAA de...

Although the concentration of N-acetylaspartate (NAA) is often used as a neuronal integrity marker, its normal temporal variations are not well documented. To assess them over the 1-2 year periods of typical clinical trials, the whole-brain NAA concentration was measured longitudinally, over 4 years, in a cohort of healthy young adults. No significant change (adjusted for both sex and age) was ...

Fig. 3. DWSI of rat brain using (a) DW-EPSI and (b) DW-LSEPSI. The left images show NAA maps and the right graphs show average spectra in the red rectangles in the left images. Yellow lines in the left images show edges of a rat head. (c) ADC map of NAA using DW-LSEPSI. Color represents ADC value. Fig. 1. Sequence diagram of DW-LSEPSI. Diffusion-weighted Line-scan Echo-planar Spectroscopic Imag...

The present study was conducted to investigate the effect of growth regulator NAA on in vitro shoot proliferation, rooting, and plantlet establishment. Among the different concentrations of NAA, the best increase in shoot weight (0.25 g) and shoot number (8.83) were observed from 0.1 mg/I NAA. The highest shoot length (2.60 cm), number of leaves (4.83), number of roots (5.15), and root length (...

Broussonetia papyrifera is an important ecological and economic tree species. The sexual reproduction of B. not only has a low germination rate, but also requires high environmental conditions. Therefore, asexual propagation using tissue culture can effectively improve the efficiency papyrifera. In this study, leaves budded shoots were used as explants, different concentrations plant growth reg...

To establish an efficient plant regeneration system of Cassia mimosoides, the 10-day-old seedlings were used as explants for inducing lateral buds. Results showed that addition BA and NAA different ratios on basis 1/2 MS could effectively induce production By adding additional elements, it was found growth buds longer stronger medium + 3.0 mg/l 0.1 4.0 Gln or 1.0 AgNO3. Meanwhile, cutting with ...

Effects of foliar spray NAA, 2, 4-D and urea on fruit yield quality Citrus limon (L.) Burm. cv. Assam lemon was studied. Nine treatments were imposed in RBD for two seasons (summer winter). Among the T6 (NAA @ 20 ppm + 2,4-D 1% urea) maximum pulp content (81.58 g/fruit), juice (40.47 ml/fruit), reducing sugar (0.51%) ascorbic acid (48.56 mg/100 g) recorded. Whereas, TSS (9.88%), total (1.66%) w...
