Efficient Growth Substrate Selection of Glomus Mosseae-colonized Trifoliate Orange (Poncirus trifoliata) Seedlings
Citrus roots need arbuscular mycorrhizal symbiosis to maintain its growth. Therefore, citrus nursery seedlings must carry out mycorrhization. The present study was conducted to research the effects of four growth substrates concluding yellow soil combination with vermiculite, perlite, peat or coir dust (I:/, v/v) on mycorrhizal development and growth performance of Glomus mosseae-colonized trifoliate orange (Poncirus trifoliata) seedlings. After 143 days of mycorrhizal inoculation, the seedlings in soil-vermiculite mix exhibited the highest mycorrhizal colonization, vesicles, arbuscules and entry points. Plant height, stem diameter, leaf number per plant, shoot and root fresh weights were the highest in the mycorrhizal seedlings treated with soil-vermiculite mix. Moreover, soil-vermiculite cultivated seedlings transformed more sucrose of leaf or root into hexose providing mycorrhizal development, thus resulting in better root morphology. It suggests that soil-vermiculite mix is an effective growth substrate of mycorrhizal trifoliate orange seedlings.
