Özet
Seeds of the tree tomato (Solanum betaceum Cav.) were treated with allelopathic plant extracts: ferula gum (FER, 0.2 g gum L-1, 25°C, 24 h), lantana petal extract (LAN, 4 g dried petal L-1, 25°C, 24 h) and marigold petal extract (TAG, 4 g dried petal L-1, 25°C, 24 h) along with an untreated control to determine the effect of these extracts on seedling emergence and performance. The pre-sowing inf luence of the allelopathic extracts (FER, LAN and TAG) on the emergence percentage (%), mean emergence time (days), emergence index, coefficient of velocity of emergence (%), seedling length (cm), seedling fresh weight (mg), seedling dry weight (mg), and stimulatory allelopathic index (%) was investigated in tree tomato seeds. The results revealed that pre-sowing treatment with the studied allelopathic plant extracts showed higher seedling emergence and performan-ce. The greatest advantage of the pre-sowing treatment was observed in the TAG treatment. Allelopathic TAG treatment resulted in 15% higher seedling emergence rates, 3.3 d faster mean emergence time, 153 mg heavier seedling weights, and higher emergence index compared to untreated seeds. In addi-tion, the effect of allelopathic FER and LAN treatments was better than the control. © 2020, Universidad Nacional de Colombia. All rights reserved.
