Stock quality and field performance of IAA-treated nursery grown branch cuttings of spiny bamboo (Bambusa blumeana Schultes)
Abstract
Effects of indoleacetic acid (IAA) and nursery cultural treatments on the stock quality of spiny bamboo (Bambusa blumeana Schultes) branch cuttings were studied in the nursery and field. Treatment with 100 ppm IAA did not increase rooting and sprouting percentages and the number and length of sprouts, but it increased the number and length of roots 20 days after planting in the nursery beds. IAA-treated cuttings potted or transplanted after 40 days still had more roots and sprouts, and longer roots than untreated cuttings. Potted and transplanted stocks had similar number of roots and sprouts and length of roots. IAA-treated and untreated stocks had similar survival in the field. However, the treated stocks had more and taller shoots of bigger diameter than the untreated stocks. A lower percentage of directly planted fresh branch cuttings survived compared to either of the potted or transplanted stocks, whether they were treated with IAA or not. Directly planted branch cuttings, whether treated with IAA or not, had the shortest, thinnest, and least number of shoots. Bamboos from IAA-treated potted stocks had more shoots than those from the other treatment combinations. Potted stocks had shoot production similar to that of transplanted stocks, with or without IAA treatment. However, the potted stocks had shoots that were significantly greater in diameter than untreated transplanted stocks.
