Nitrogen (N) is critical for zinc (Zn) absorption into plant roots; this in turn allows for Zn accumulation and biofortification of grain in winter wheat (Triticum aestivum L.), an important food crop. However, little is known about root morphology and subcellular Zn distribution in response to N treatment at different levels of Zn supply. In this study, two nutrient solution culture experiment...

The galanthamine, lycorine, and lycoramine content of Lycoris chinensis was researched during development from young to old plants, i.e. in seeds, ten-day-old seedlings, three-month-old seedlings, one-year-old seedlings, and perennial seedlings. Notably the alkaloid level reduced to its lowest content 10 days after seed germinating. Then the accumulation of galanthamine tended to increase with ...

we investigated the response of sea buckthorn to drought in a nursery experiment that has been studied for the first time in the world for iranian sea buckthorn. biomass and physiological differences in response to drought were compared between four elaeagnus rhamnoides seedlings inhabited in qazvin province origin seeds of iran. the experimental design included four water regimes including 2, ...

The objective of this study was to investigate the effect of pruning in different developmental stages on growth, development, seed yield and active substances of medicinal pumpkin (these active substances are uses for remedy the Benign Prostatic Hyperplasia (BPH)). The experiment was performed in a RCB design. Five pruning treatments in different developmental stages (no pruning, after 3-5 nod...

redbud (cercis griffithii) is an iranian native species that plays a crucial role in protecting soil and water in zagros forestsareas. although many reforestation projects of this species in this area were unsuccessful, the restoration of redbud must continue using new applied studies to help conserve this precious resource. this can be achieved through increasing the quality and quantity of se...

We determined the enzyme activities involved in the aerobic and anaerobic respiration of Kosteletzkya virginica on the 0, 10, 20, and 30 d of waterlogging to understand its respiratory characteristics. We also determined the enzyme activities on the 10 and 20 d of recovery after water drainage. Non-waterlogged seedlings were regarded as control during this experiment. All waterlogged seedlings ...

abstract effect of cr3+ concentrations (1, 2, 4, 6, and 8 mg l-1) on lipid peroxidation / mda production and antioxidative enzyme activity (apox, sod, and ppox) in root and leaf tissues of sweet basil seedlings (ocimum basilicum l.) during 6week treatment in hydroponic culture was studied. increasing cr3+ in the culture medium (≥4 mg l-1) caused significant enhancement of apox, sod, and ppox ac...

Pea seeds were swollen in solutions with different concentrations of cytokinin benzyladenine (BA). As compared with controls, a low concentration of BA (0.05 mg/l) did not affect the growth of stems and roots of twelve-day-old seedlings but concentrations of 0.20–4.00 mg/l showed an inhibiting effect; this inhibition was proportional to the concentration of BA. In controls the ratio between the...

Papaya is one of the leading tropical fruit that very potential to be developed in Indonesia. Various treatments solve dormancy papaya seeds have been done, from sarcotesta disposal and administration, temperature treatment has shown varying results, so there still no definite information about way or which most appropriate for breaking seeds. Therefore, researchers wanted do research on Develo...
