Correlation and PCA studies in CPPU applied mango (Mangifera indica L.) cv. “Dusehri”


Naveena Kumara KT, Harminder Singh and Nirmaljit Kaur

The present investigation aimed to study the correlation and principle component analysis of N1-(2-chloro-4-pyridyl)-N3-phenyl urea (CPPU) on fruit retention, yield, and quality of mango cv. Dusehri during 2019-20 and 2020-21 at Punjab Agricultural University, Ludhiana, India. The growth hormones promoting fruit retention such as CPPU (@ 5, 10, and 15 ppm), salicylic acid (@ 100, 200, and 300 ppm) and 2,4-dichlorophenoxyacetic acid (2,4-D) (@ 20 ppm), and were sprayed during pea stage of fruit growth. Fruit yield was significantly and positively associated with fruit retention at the marble and harvest stage, fruit length, fruit diameter, number of fruits per plant, fruit weight, fruit pulp weight, firmness, shelf life, fruit TSS, total sugar and TSS: acidity ratio. However, fruit yield was significantly and negatively correlated with fruit acidity and fruit cracking.
