simply waits until three vital environmental conditions have been simply waits until three vital environmental conditions have been met: water supply, temperature, well oriented living conditions met: water supply, temperature, well oriented living conditions (Capon 1990). Most seeds will of course only germinate between (Capon 1990). Most seeds will of course only germinate between certain temperatures, in this case I used room temperature for my certain temperatures, in this case I used room temperature for my bases. A steady temperature between these limits is bases. A steady temperature between these limits is recommended-fluctuating temperatures can damage a seedling in recommended-fluctuating temperatures can damage a seedling in its critical early stages. Indeed if a seed is not allowed to its critical early stages. Indeed if a seed is not allowed to germinate (sprout) within some certain length of time, the embryo germinate (sprout) within some certain length of time, the embryo inside will die. I have not been able to find any ajoining inside will die. I have not been able to find any ajoining expirement dealing with sodium bicarbonate. Although, expirement dealing with sodium bicarbonate. Although, throughout its early stages of survival the seedling is completely throughout its early stages of survival the seedling is completely dependent upon food supplies from the storage structures of seed dependent upon food supplies from the storage structures of seed cotyledons and endosperm (Capon 1990). The seed must be cotyledons and endosperm (Capon 1990). The seed must be looked upon as a tiny embryonic plant of the new generation, with looked upon as a tiny embryonic plant of the new generation, with enough stored food to start it off in life and seeds coats for enough stored food to start it off in life and seeds coats for protection (Swingle 1935). This in accordance makes my protection (Swingle 1935). This in accordance makes my accretion that the sodium bicarbonate will not add nutritional accretion that the sodium bicarbonate will not add nutritional value to the process just adding negativity to it. That leads case to value to the process just adding negativity to it. That leads case to my ideals of stunted growth unlike the nutritional value of my ideals of stunted growth unlike the nutritional value of distilled water.distilled water.
HypothesisHypothesis
If increased sodium adds to If increased sodium adds to reduction in the growth in plants, reduction in the growth in plants, then germinating carrot seeds in a then germinating carrot seeds in a Sodium Bicarbonate solution will Sodium Bicarbonate solution will reduce the seeds growth along with reduce the seeds growth along with germination scale. germination scale.
