In 1976,Journal of the American Society for Horticultural Science included an article by Lee, C. I.; Hackett, W. P.. Category: indole-building-block. The article was titled 《Root regeneration of transplanted Pistacia chinensis Bunge seedlings at different growth stages》. The information in the text is summarized as follows:
The root-regenerating potential (RRP) of 1-year-old P. chinensis seedlings at different growth states, was determined by recording the number of newly initiated roots during 4 weeks after bareroot transplanting into a bottom misting chamber. RRP of intact pistacias was greatest when leaves were fully expanded and the terminal bud was forming (stage III), and lowest when seedlings were dormant (stages V and VI). However, seedlings disbudded before transplanting and root cuttings showed 2 peaks in RRP; 1 at spring bud break (stage I) and the other at stage III. Removal of buds resulted in decreased RRP at stage I, but had little effect when plants were dormant. Thiourea [62-56-6] sprays of growing seedlings and chilling of dormant seedlings enhanced bud break and RRP. K indolebutyrate [60096-23-3] applied to the root system promoted RRP but did not eliminate the seasonal variation of RRP. K indolebutyrate could replace the influence of buds only when seedlings were not dormant. Sucrose [57-50-1] feeding via the stem increased RRP at spring bud break. Dormant condition of buds and the availability of carbohydrates are the factors controlling the RRP of bareroot transplanted pistacias. In the experiment, the researchers used many compounds, for example, Potassium 4-(1H-indol-3-yl)butanoate(cas: 60096-23-3Category: indole-building-block)
Potassium 4-(1H-indol-3-yl)butanoate(cas: 60096-23-3) is auxin-family plant hormone, and is thought to be a precursor of indole-3-acetic acid (IAA) the most abundant and the basic auxin natively occurring and functioning in plants. IAA generates the majority of auxin effects in intact plants, and is the most potent native auxin.Category: indole-building-block
