THE EFFECT OF FLOWER AND BOLL THINNING ON QUALITY PARAMETERS OF CUT MOBYDICK (GOMPHOCARPUS PHYSOCARPUS) FLOWERS

A.O. Watako, C.N. Mundia
A study was carried out to investigate the effect of flower and boll thinning on the quality of harvested mobydick flowers. Thinning treatments were applied at three stages of development; 7, 21 and 35 days after full bloom (FB) of flowers at a cluster in the respective lateral branch. An unthinned control was also included. Thinning treatments significantly improved cumulative stem length compared to unthinned control. Thinning at FB+35d had significantly longer mean stem length of 92.9 cm, whilst thinning at FB+21 d and FB+7 d had 76.4 and 57.1 cm mean stem lengths respectively (p<0.0001). Shorter mean stem length of 46.1 cm at harvest was obtained with no thinning. Significantly higher mean number of bolls; 32 was obtained with thinning at FB+21 d, while no thinning gave 16 mean number of bolls (p<0.0001). Thinning at FB+35 d and FB+7 d recorded equal number of bolls of 28. Thinning significantly influenced stem thickness and weight. Thinned plants had significantly larger mean stem thickness (10.4 cm), and significant heavier mean stem weight (570.3 g), while unthinned plants had 7.4 cm mean stem thickness and 276 g mean stem weight respectively (p<0.0001). However, thinning did not significantly influence maximum or minimum diameter of bolls, although thinned plants had higher boll diameters than unthinned plants.
