Bamboo propagation through conventional methods like seeds and rhizome has limitations of availability pose practical and economic constraints and are, by and large non-sustainable. To overcome the situation, macro-propagation efforts of commercially important Bambusa tulda Roxb. and Bambusa nutans Wall. have been endeavored. Season and cuttings’ thickness is influential in determining rooting ability in culm-branch cuttings of these two species. Age of donor culm, treatment concentration and duration, rooting substratum, temperature, and humidity are other affecting factors. Present study exhibited initiation of sprouts within a week after planting of cuttings, whereas adventitious rooting initiates in 20 days after planting. Culm-branch cuttings planted during spring–summer in March and sampled after 60 days reveals 63.39% and 72.68% rooting ability, respectively in ≤ 2.0 cm diameter (thin) and > 2.0 cm diameter (thick) cuttings of Bambusa tulda and 73.60% and 69.02% rooting ability, respectively in thin and thick cuttings of Bambusa nutans. Rooting ability of branch cuttings decline in rainy season followed by autumn–winter in two diameter classes of both species. Sprout number, sprout length, number of primary adventitious roots, and root length of the longest root was comparatively higher during spring–summer than rainy and autumn–winter season in thin and thick cuttings of both species. Propagation through culm-branch/sub-branch cuttings is without hampering economic value of culms and therefore, a non-destructive, cheap, and easy to handle technique of large scale production of planting stock. Strong relationship between season and rooting ability will help in achieving planting stock production targets of forest nurseries.

通过种子和根茎等传统方法进行的竹子繁殖具有可用性限制，带来了实际和经济上的限制，并且大体上是不可持续的。为了克服这种情况，具有重要商业价值的Bambusa tulda Roxb 进行了宏观传播。和Bambusa nutans墙。一直在努力。季节和扦插的粗细对决定这两种茎枝扦插的生根能力有影响。供体秆的年龄、处理浓度和持续时间、生根基质、温度和湿度是其他影响因素。目前的研究表明，插条在种植后一周内萌芽，而不定生根在种植后 20 天开始。在 3 月春夏期间种植并在 60 天后取样的秆枝扦插显示 63.39% 和 72.68% 的生根能力，分别在直径 ≤ 2.0 厘米（薄）和直径 > 2.0 厘米（厚）的竹枝扦插和 73.60% 和 73.60% 和69.02％的在薄和厚的插条生根分别能力，竹碱草. 两个树种的两个直径等级的枝条生根能力在雨季和秋冬季下降。春夏两季薄、厚扦插的芽数、芽长、初级不定根数和最长根的根长均高于雨季和秋冬季。通过茎秆/小枝扦插繁殖不会影响茎秆的经济价值，因此是一种无损、廉价且易于操作的大规模种植砧木技术。季节与生根能力之间的密切关系将有助于实现林木苗圃的种植种群生产目标。
