Abstract
The present study was carried out to study certain growth and physiological expressions of malformation in 4 mango varieties, Amrapali, Dashehari, Langra and Mallika.
The effect of pruning on the reappearance of malformation was also studied.
Leaf area, length of 30 days old panicle, number of developed nodes/panicle, length of 10 elongated internodes of primary rachis and length of 10 elongated internodes of secondary rachis were significantly reduced, however, number of shootlets or panicles developed/apical zone were significantly increased in malformation than normal.
The number of hermaphrodite flowers/panicle and pollen viability of hermaphrodite and male flowers were insignificantly affected due to malformation.
Significant reduced nitrate reductase activity, nitrogen and soluble sugar content as well as the significant increase and presence of starch, auxins, gibberellins, abscisic acid and some unknown type of hormone like substances were observed to be involved in mango malformation.
Pruning upto 20 cm proved successful in the non-reappearance of malformation.
