Radicle emission was observed since 72 h and considering the 120-hour period, all the replications presented at least one germinated seed when the experiment was ended.
Efficacy of germination was measured in terms of weight gain, radicle size and percent germination.
This reduction is due to the osmotic potential that inhibits the absorption of water and intake of nutrients by radicle [29].
Germinated seeds were counted daily by radicle protrusion till the number of germinated seedlings remained constant.
Previous studies indicated positive influences of hydro-priming on radicle length [18].
Models for the responses of seed germination One seed is considered germinated just after radicle protrusion indicating the presence of a normal seedling capable of developing a normal plant under field conditions.
Seeds were dissected under a stereomicroscope and the degree of the development of each embryo was assessed visually using a six-point scale (1--embryo length less than 1/4 of the seed length, embryo is heart-shaped; 2--embryo length ca 1/4 of the seed length, cotyledons and radicle of equal length; 3--embryo length ca 1/3 of the seed length, pronounced cotyledons and radicle; 4--embryo length ca 1/2 of the seed length, radicle twice as long as the cotyledons, cotyledons leafy; 5--embryo length 2/3 of the seed length; 6--embryo length nearly equal to the seed length).
Underdeveloped, linear embryos, which must elongate to a critical length before radicle emergence are a common feature of Amaryllidaceae species (Baskin and Baskin, 1998).
A radicle invasion by a red reed overgrew and ate up a hotrod road so disliked by a certain fish that was recently the Prime Minister of Australia.
The effect of shell bio-oil on germination and radicle growth of seeds depended on pyrolysis temperature, fraction, and dilution rate.
