Description

Effects of five plant growth regulators on formation and development of branching were investigated for broccoli variety 'Wase-Midori' and 'Green-18', which were different in branching property. 1. The terminal curd weight of Wase-Midori was not affected by the growth regulators, but the increased lateral shoot weight was pronounced in the benzyladenine, ethephon, morphactin and TIBA plots. 2. Effects of the growth regulators on the terminal curd weight of Green-18 were not recognized but the increased weight of lateral shoots was slightly smaller in the morphactin plot but larger in the TIBA plot, compared with the control. 3. Mean weight of a lateral shoot of Wase-Midori was not affected by the growth regulators but the increased number of lateral shoot per plant increased in the benzyladenine, ethephon, morphactin and TIBA treatments, notably by benzyladenine. 4. Mean weight of a lateral shoot of Green-18 was not affected by the growth regulators but the increased number of lateral shoot per plant was slightly smaller in the morphactin plot. 5. Terminal curd weight of Wase-Midori was not affected by the treatment with benzyladenine. But the increased lateral shoot weight was more pronounced parallel with the concentration of benzyladenine. 6. Though mean weight of a lateral shoot of Wase-Midori was not affected with benzyladenine, the higher the concentration of benzyladenine, the more the number of lateral shoot per plant increased.

分枝特性の異なる'早生緑ハナヤサイ'と'Green-18'を用い, 側枝の発育に及ぼす5種類の生長調節物質の影響を調べた. 1. 早生緑の頂花らい重に対する生長調節物質の影響は認められなかったが, 側枝重はベンジルアデニン, エセフォン, モルファクチン, TIBA処理により増加した. 2. Green-18の頂花らい重に及ぼす生長調節物質の影響は認められなかったが, 側枝重はモルファクチン処理で減少し, TIBA処理で増加した. 3. 生長調節物質処理の早生緑の平均側枝重に対する影響は認められなかったが, ベンジルアデニン, エセフォン, モルファクチン, TIBA処理では, 株あたりの側枝数は増加した. 4. Green-18の平均側枝重に生長調節物質処理の影響は認められなかったが, 株あたりの側枝数はモルファクチン処理により減少した. 5. 早生緑にベンジルアデニンを処理することにより, 頂花らい重にはその影響は認められなかったが, 側枝重はその高濃度ほど増加した. 6. 早生緑の平均側枝重にベンジルアデニン処理の影響は認められなかったが, 側枝数は高濃度区ほど増加した.
