in order to evaluate genetic diversity among squash landraces from northwest iran by morphological and physiological traits, 18 squash landraces belong to pumpkin, ornamental and confectionary groups were planted in completely randomized block design with three replications in agricultural research center of urmia in 2013. morphological characteristics related of fruit, seed, leave and flower a...
Slow magneto-acoustic waves are often observed in polar plumes and active region fan loops. The observed periodicities of these waves are in the range of 1- 40 minutes. Mainly, the ratio of damping time to the oscillation period is less than 2 (equal to the ratio damping length to the wave length), which corresponds to the strong damping regime. In general, slow magneto-acoustic waves can be da...
topical application with 100, 200 and 300 ng/ml phytohormone salicyclic acid on commercial traits was analysed in bivoltine csr2, csr4 and csr2xcsr4 crossbreed races of the silkworm, bombyx mori l. the results showed that there was significant increase in larval weight female cocoon weight, male cocoon shell weight, and hatching percentage with 100 and 200 ng/ml, silkgland weight, female cocoon...
Sexual dimorphism in the ratio of digits length is a morphological feature resulted from the interaction between sex hormones and prenatal Hox genes, the latter is known to control the development of both limbs and genitals. The status of this trend and ratios have been investigated in various animal groups, including humans, other mammals, birds, reptiles, and amphibians. In this study, the bo...
the use of recent technologies for the increase of growth indexes and the plants yields is an important aspects and till now many research works for this has been done. one of these efforts is the usage of magnetic water and zeolite for the increase of yield plants. this research work is an study on the effects of magnetic water and zeolite that has been done on frame work of pore random design...
