在本试验的初步研究中调查了用抗旱的无性系茶树在嫁接中做砧木,以增强高产但不抗旱的无性系茶树的耐旱力的可能性。 众所周知,在干旱丘陵茶区的高产无性系品种如2023和2026抗旱性总是差于低产无性系品种如DN、2025和CY-9。近期的研究已揭示出茶树无性系品种抗旱性不同的一个重要因素是由于它们的根系生长的深度不同(Nagara-
In this pilot study, we investigated the possibility of drought-resistant clones using drought-resistant clones of tea plants as grafts in grafting to enhance the drought resistance of high-yielding but non-drought-resistant clonal tea plants. It is well-known that the drought resistance of high-yielding clones such as 2023 and 2026 in the dry hilly tea areas are always worse than those of low-yielding clones such as DN, 2025 and CY-9. Recent studies have revealed that one important factor in different drought resistance of tea tree clones is their depth of root growth (Nagara-
