Autotoxicity of root exudates from strawberry in hydroponic culture

Effects of Plant Residue, Root Exudate and Juvenile Plants of Rapeseed (Brassica napus L.) on the Germination, Growth, Yield, and Quality of Subsequent Crops in Successive and Rotational Cropping Systems

“…For example, Bi et al (2010) reported autotoxic inhibitory activity of the soil attached to commercially cultivated American ginseng. Kitazawa et al (2005) reported that strawberry root exudates acted as a potent growth inhibitor. And Asao et al (2008) reported that electrodegradation of the root exudates could alleviate the autotoxicity.…”

Autotoxicity in Vegetables and Ornamentals and Its Control

“…2,4-dichlorobenzoic acid (DCBA)-degrading microbial strains, may degrade DCBA including other growth inhibitors exuded from cucumber roots and avoid autotoxicity in cucumber resulting increased fruit yield (Asao et al, 2004a). In strawberry we found vegetative and reproductive growth inhibition due to autotoxicity developed in non-renewed nutrient solution through accumulation of autotoxic root exudates, and the most potent inhibitor was benzoic acid (Kitazawa et al, 2005). Foliar application of auxin such as 1-naphthaleneacetic acid (NAA) avoided the growth reduction of strawberry caused by autotoxicity.…”

“…Growth of some vegetables such as asparagus, taro, cucumber, and tomato was inhibited by allelochemicals found in their root exudates (Asao et al, 1998a(Asao et al, , 2003(Asao et al, , 2004bShafer & Garrison, 1986;Yang, 1982;Yu & Matsui, 1993). Inhibition in growth of apple, peach, rice, strawberry, and sugarcane has been documented for the autotoxicity (Kitazawa et al, 2005;Mizutani et al, 1988;Rice, 1984). This autotoxicity in tomato (Yu et al, 1993) and cucumber (Asao et al, 1998a;Pramanik et al, 2000) has been recovered by addition of AC to the nutrient solution, because the added AC adsorbed the phytotoxic root exudates and thus favored plant growth.…”

“…It leads to resurgence of disease pest, exhaustion of soil fertility, and developing chemical interference in the rhizosphere referring allelopathy (Hegde & Miller, 1990;Komada, 1988;Takahashi, 1984;Young, 1984). Allelopathic effects from crop residues and root exudates have extensively studied in vegetable crops such as in alfalfa (Miller, 1983;Nakahisa et al, 1993Nakahisa et al, , 1994Chon et al, 2002, Chung et al, 2011, asparagus (Young, 1984;Young & Chou, 1985;Hartung et al, 1990), cucumber (Yu & Matsui, 1994, 1997, watermelon (Kushima et al, 1998;Hao et al, 2007), taro (Asao et al, 2003), strawberry (Kitazawa et al, 2005), tomato (Yu & Matsui, 1993b), lettuce (Lee et al, 2006) and so on. Therefore, growth of these plants found to be inhibited by the released allelochemicals.…”

Integrated Biological and Cultural Practices Can Reduce Crop Rotation Period of Organic Strawberries

“…Cao and Wang (2007) showed that root exudates from strawberries inhibited the growth of strawberries due to autotoxicity. In hydroponics, Kitazawa et al (2005) identified the causal compound of strawberry autotoxicity as benzoic acid. Further, Asao et al (2008) demonstrated that destroying benzoic acid by electrodegradation in hydroponic strawberries increased the plant growth and fruit yield.…”
