چکیده
The Indian leadwort (Plumbago indica L.) of the family Plumbaginaceae is a plant with high pharmaceutical value, as it contains plumbagin, naphthoquinone antibacterial, antifungal and anticancer properties. Among propagation methods for leadwort, in vitro considered an effective method producing disease-free transplants short period time rate. When plants grown are transferred to ex condition, environmental factors nursery house such light, temperature, humidity microorganism soil will affect their growth. Characteristics themselves also critical subsequent It is, thus, essential establish standards evaluate qualify transplanting condition. these standards, culture age affects maturations root, stem leaves, which can turn influence acclimating ability growth after transplantation. purpose this study investigate effects on performance during stage. For purpose, three different ages uniform plants, 35, 42 49 day-old, were studied. After 28 days cultivation under light intensity 70 ± 10 µmol m-2 s-1, temperature 35 4 oC relative (RH) 60 10%, all treatments achieved 100% survival Increased fresh dry weights percentage matter condition not statistically between day-old but significantly plants. development shoot root stage was more balanced, shown by higher ratio shoot/root weight, than results showed that Plumbago species, bigger led better These indicated possible transfer 5 weeks

I-homomorphism for BL-I-General L-fuzzy Automata
Taking into account the notion of BL-general fuzzy automaton, in the present study we define the notation of BL-intuitionistic general L-fuzzy automaton and I-bisimulation for BL-intuitionistic general L-fuzzy automaton.Then for a given BL-intuitionistic general L-fuzzy automaton, we obtain the greatest I-bisimulation. According to this notion, we give the structure of quotient BL-intuiti...

I I . I I I I I I I I _ I on a Class of Permutation Tests for Stochastic Independence
asymptotically most powerful permutation (rank order) tests is offered for testing independence of two stochastic variates when the observable random variables correspond to a finite or countable set of contiguous cells having an underlying continuous distribution. The theory is illustrated by some examples.
متن کاملEffect of the Addition of Insulin Like Growth Factor-I (IGF-I) on Cryopreservation of Hariana Bull Semen
This experiment was designed to study the effect of insulin like growth factor-I (IGF-I) on cryopreservation of Hariana bull semen. For this purpose, semen ejaculates were collected from four Hariana bulls using artificial vagina at biweekly interval. The semen samples which possess more than 70% initial progressive motility and above 500 million/mL spermatozoa concentration was subsequently su...
