Seed Quality In Radish As Affected By Age Of Stecklings, Spacing Combinations and Plant Growth Regulators

Abstract

The present investigation was conducted at Division of Vegetable Science and Floriculture, SKUAST-Jammu for the two consecutive years 2013-14 and 2014-15.The investigation involved age of stecklings (70 days and 85 days old ), spacing combinations (60x60 cm and 90x90 cm ) and three levels of growth regulators GA3 and NAA each with one control as water spray.The results revealed that age of stecklings (70 days old) affected number of siliqua per plant (848.24) and length of siliqua (4.45) significantly. Maximum number of siliqua per plant (861.98), number of seeds in siliqua (6.96), 1000 seed weight (13.72), seed yield per plant (59.19), seed vigour index in vivo (1507.22), seed vigour index in vitro (1531.58), seed germination percentage in vivo (88.83) and seed germination percentagein vitro (92.50) were recorded with plant regulator GA3@ 200 ppm followed by NAA @ 100 ppm. The spacing combination of 90x90 cm resulted in maximum number of siliqua per plant (832.67), 1000 seed weight (12.51), seed vigour index in vivo (1436.07) and seed vigour index in vitro (1457.26).
