Study of the Growth and Development Rhythm and Phenological Characteristics of the Progeny of Albizia odoratissima Elite Trees
摘要
Abstract
To understand the growth rhythm and phenological characteristics of young superior Albizia odoratissima progeny to provide references for efficient cultivation and seed orchard management,we analyzed annual growth variations and phenological phases in plantation-grown saplings.Results showed that in the second year,mean annual increments reached 2.82 m(height),2.34 cm(DBH),and 0.008 075 m3(volume),with monthly rates of 5.68%,5.48%,and 17.54%,respectively.Significant monthly variations occurred(p<0.05),with maximum DBH(11.97%)and volume(42.20%)growth rates in March,and peak height growth(10.99%)in August.Among families,#28 presented greater monthly increments(0.37 m height,0.30 cm DBH,0.000 262 m3 volume;p<0.05).Phenological observations showed that the germination stage of A.odoratissima occurred in March,the leaf spreading stage occurred in April,the flowering stage occurred in late May-early June,the fruit setting stage occurred in mid-late June,the fruit expansion stage occurred in July,the peak fruiting period is from August to October,the fruit ripening stage occurred in November,and the leaf shedding stage occurred in December.The following years included February(initial fruit drop),March(peak leaf fall),early April(final leaf drop),and May(final fruit drop).A.odora-tissima has nearly continuous growth with rapid growth periods in March and August.Recommended management includes supplemental fertilization during January-March and June-August to support growth.Family#28 presented superior growth traits,warranting further monitoring.Optimal artificial pollination should occur in May,with seed collection occurring from February to March.关键词
