采用遮荫(全光照、遮荫75%)裂区下的L9(34)正交设计对云南松种子进行微波辐射( A1、A2、A3分别为0、5、10 s)、IBA浸种( B1、B2、B3分别为0、0.10、0.20 g· L-1)试验,探究其对云南松苗木地径和苗高生长的影响。结果表明,因受微波辐射与IBA极显著交互作用的影响,在全光照条件下,苗木地径的实际优水平组合为A2 B1(微波辐射5 s+清水浸种)、A3 B2(微波辐射10 s+IBA 0.10 g· L-1浸种),与理论优水平组合A1 B1(对照)不符;遮荫75%条件下,理论优水平组合与实际优水平组合一致,均为A1 B3(无辐射+IBA 0.20 g· L-1浸种)。2种小环境苗高的优水平组合均为A1 B2(无辐射+IBA 0.10 g· L-1浸种),与实际结果相一致。微波辐射抑制云南松苗木生长;与之相反,IBA浸种促进苗高生长,IBA 0.10 g· L-1浸种效果最好。在其他条件一致的情况下,全光照苗木的平均地径极显著大于遮荫苗木的平均地径,而平均苗高极显著低于遮荫苗木的平均苗高。
採用遮蔭(全光照、遮蔭75%)裂區下的L9(34)正交設計對雲南鬆種子進行微波輻射( A1、A2、A3分彆為0、5、10 s)、IBA浸種( B1、B2、B3分彆為0、0.10、0.20 g· L-1)試驗,探究其對雲南鬆苗木地徑和苗高生長的影響。結果錶明,因受微波輻射與IBA極顯著交互作用的影響,在全光照條件下,苗木地徑的實際優水平組閤為A2 B1(微波輻射5 s+清水浸種)、A3 B2(微波輻射10 s+IBA 0.10 g· L-1浸種),與理論優水平組閤A1 B1(對照)不符;遮蔭75%條件下,理論優水平組閤與實際優水平組閤一緻,均為A1 B3(無輻射+IBA 0.20 g· L-1浸種)。2種小環境苗高的優水平組閤均為A1 B2(無輻射+IBA 0.10 g· L-1浸種),與實際結果相一緻。微波輻射抑製雲南鬆苗木生長;與之相反,IBA浸種促進苗高生長,IBA 0.10 g· L-1浸種效果最好。在其他條件一緻的情況下,全光照苗木的平均地徑極顯著大于遮蔭苗木的平均地徑,而平均苗高極顯著低于遮蔭苗木的平均苗高。

The L9 (34 ) orthogonal design was applied to find out the effects of microwave radiating (A1 ,A2 and A3 were 0,5 and 10s) and IBA solution presoaking seeds(B1 ,B2 and B3 were 0,0.10 and 0.20 g· L-1 ) on basal diameter (BD) and seedling height(SH) growth of Pinus yunnanensis seedlings under shading split plots (Sunshining nursery and 75% shading).The results showedthat the optimal BD treatment combination (TC) were A2 B1 (microwave radiating 5 s +warer presoaking seeds) and A3 B2 (microwaveradiating 10 s +0.10 g· L-1 IBA solution presoaking seeds) under sunshining nursery,which differed the theory optimal TC ofA1 B1 (CK) since there was significant interaction effect between microwave radiating and IBA solution presoaking seeds ;and the theoreticand practical optimal TC of the BD was A1 B3 (no microwave radiating +0.20 g· L-1 IBA solution presoaking seeds) under75% shading nursery.The optimal SH TC of the theory and practice was A1 B2 (no microwave radiating +0.10 g· L-1 IBA solutionpresoaking seeds) under the both microsites.Microwave radiating seeds restrained the growth of Pinus yunnanensis seedlings. In contract,The IBA solution presoaking seeds promoted the growth of SH ,the best concentration was 0.1 g· L-1. The BD under the sunshiningnursery was significantly greater than the 75% shading nursery. However,the SH was significantly shorter than which of the75% shading nursery.
