2006年4月8月对香梨新梢、果实生长动态进行调查。结果表明:香梨新梢整个调查过程中,前期新梢生长较快,而后期生长迅速下降。对果实生长动态调查中,与新梢生长同步这一段时期,果实纵横径增长量不大,而当新梢停长后,果实生长量突然加快,且生长期间出现了三个生长高峰。 April 2006 August investigation of pear shoots, fruit growth dynamics. The results showed that during the whole investigation of pear shoots, the shoots of early stage grew faster and the stage of later growth decreased rapidly. In the dynamic investigation of fruit growth, the growth of fruit length and width did not increase greatly during the period of synchronization with shoot growth.
