Performance of Different Gladiolus (Gladiolus grandiflorus L.) Varieties on Growth and Flowering attributes under Agro-ecological conditions of Tandojam

Abstract

The present research was conducted during 2024-25 at Horticulture Garden, Sindh Agriculture University, Tandojam to evaluate the growth and flowering performance of different gladiolus varieties under Agro-ecological conditions of Tandojam. The experiment was laid out in Randomized Complete Block Design (RCBD) with four blocks. The corms of four varieties of gladiolus viz: Pink, Indian, Yellow and White Prosperity were planted during the month of October, 2024. The results revealed that the maximum plant height (92.65 cm) chlorophyll content of leaves (76.85 SPAD), large size of inflorescence (16.07cm), maximum length of leaves (21.97cm), Leaves plant^-1 (12.00) and Sturdiness quotient (6.28) were recorded in the Indian variety. Whereas larger flower diameter (82.62mm), maximum fresh weight of flower (4.63 g), number of florets Spike^-1 (14.00), maximum plant collar diameter (19.65 mm) and maximum sprouts corm^-1 (3.00) were recorded in white Prosperity variety. However, total soluble solids of petals (9.75 Brix), thickness of leaf (0.66mm) and petal thickness (0.33mm) were recorded maximum in the Pink variety. It is concluded that vegetative grower parameters were observed in Indian while flowering attributes were observed better in White Prosperity variety.
