abstract

in order to evaluation the effect of drought stress on germination indices and early seedling growth of medicinal herb dill (anethum graveolens l), an experiment was conducted in the agricultural laboratory of urmia payam noor university in 2015 as a randomized complete block design with four replications. treatments were five levels of drought stress (0, -1, -2, -3 and -4 bar induced by polyethylene glycol, which was considered zero bar as control). in this research were measured, root, stem and seedling dry weight, germination percent, germination rate, germination uniformity, rate germination index, mean germination time, mean rate of germination, coefficient of velocity of germination, amount germination index, seedling weight vigor index, seedling length vigor index, seed vigor index, reduction percent of seed weight, root tolerance index and stem tolerance index. the results of analysis variance showed that effect of different level of drought stress on all of studied in this research had significantly at 1% probability level. mean comparison revealed that with increasing drought stress, root, stem and seedling dry weight and total germination indices exception mean germination time decreased significantly. drought stress of -4 and -3 bar in compared with control treatment, seedling dry matter decreased 95 and 87 percent, respectively. there are high positive correlation between germination indices and tolerance indices to drought stress with morphological traits such as root, stem and seedling dry weight, and we can use these traits to assess resistance to drought stress during seed germination and seedling of dill.

Effects of Anethum graveolens L. (dill) on Oocyte and Fertility of Adult Female Rats

BACKGROUND Our previous studies revealed Anethum graveolens L. caused some changes in female reproductive system that induced infertility. Therefore, in this study, oocyte changes as one of probable reasons of infertility were investigated. METHODS In this study, 59 adult female rats were divided into 3 groups of control, low dose (0.5 g/kg) and high dose (5 g/kg) of dill seed aqueous extract...

Effects of drought stress on the seed germination and early seedling growth of the endemic desert plant Eremosparton songoricum (Fabaceae)

Eremosparton songoricum (Litv.) Vass. is an endemic and extremely drought-resistant desert plant with populations that are gradually declining due to the failure of sexual recruitment. The effects of drought stress on the seed germination and physiological characteristics of seeds and seedlings were investigated. The results showed that the germination percentage decreased with an increase of p...

Seed germination of dill (Anethum graveolens L.) in response to salicylic acid and halopriming under cadmium stress.

Seed priming is a technique which is potentially able to promote rapid and more uniform seed germination and plant growth as well. In this regards, the presowing effects of seed priming treatments were investigated on some physiological viz. seed germination, germination rate, radicle elongation, shoot elongation, radicle dry weight, shoot dry weight and vigor index. Seeds were subjected to two...
