摘要: The exudation of soluble carbon compounds from Zea mays roots was investigated over a 10 day growth period under sterile and non-sterile solution culture conditions. results showed that plants grown in static culture, where C allowed to accumulate, released 8 times less than conditions which the solutions were replaced daily. increased loss plant cultures exudates removed daily attributable to, (a) reduced potential for root re-sorption previously lost C, (b), increasing diffusion gradients between surrounding bathing passive leakage [...]
