一、推迟锯砧对芽接桩发芽的影响在芽接苗推迟锯砧试验中,用RRIM600、RRIM703、PB235和PB251四个无性系进行芽接,它们在芽接桩芽片芽的萌发方面没有显著的差异。芽接后推迟锯砧的不同时间对平均抽芽率的影响见表1。芽接后随着锯砧时间的推迟(从2个月递增至12个月),其抽芽率也随着普遍地降低。抽芽率的差异初期最大,定植大田后第3到7周内表现明显。大多数的芽是在
First, postponed the effect of sawing anvil on the sprouting of sprouting pile in budding seedling delayed saw anvil test, using RRIM600, RRIM703, PB235 and PB251 four clonal budding, bud bud bud sprout germination of them there is no significant difference. Table 1 shows the effect of budding and postponing saw anvil on average germination rate at different times. Budding followed by a sawtooth time delay (from 2 months to 12 months), the rate of its budding has also been generally reduced. Differences in the rate of budding the initial maximum, colonized the field after the first 3 to 7 weeks obvious. Most buds are on
