Abstract/ Executive Summary:

An experiment was conducted to find out the suitable plant growth regulator(s) for inducing parthenocarpic fruit in kakrol (Momordica dioicia Roxb). Four plant growth regulators, viz. NAA and 2, 4-D (Auxins), Fulmet (Cytokinine) and GA₃ (Gibberellic acid) were sprayed at three stages (a day before anthesis, at anthesis, a day after anthesis). Out of four growth regulators 2, 4-D and fulmet induced parthenocarpic fruit development. Fruit set percent, final fruit weight, fruit length and fruit diameter varied significantly with different treatment combinations. 2, 4-D at 50 ppm when applied at anthesis showed better performance in inducing parthenocarpy.

Keywords: Momordica dioica, Plant growth regulators, Parthenocarpic fruit

Location: Experimental field under Department of Genetics and Plant Breeding, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur,

Start Date: 00-03-2004

End Date: 00-09-2004

Program Area: Crop-Soil-Water Management

Commodity: Teasle Gourd

Objectives:

The present investigation was designed to identify a growth regulator and suitable stage of application for inducing parthenocarpy in kakrol.

Methodology:

The experiment was conducted at the experimental field under Department of Genetics and Plant Breeding, Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, during the kharif season (March to September, 2004) on an upland soil. The tuberous roots of a local genotype were used in this study. The experiment was carried out in a split plot design with three replications. The treatments imposed were time of application of growth regulator, one day before anthesis (A₁), at anthesis (A₂), one day after anthesis (A₃) and different plant growth regulators: 2, 4-D: (2, 4-dichlorophenoxy acetic acid) (H₁), Fulmet (H₂), GA₃: Gibberellic acid (H₃), NAA: nepthalene acetic acid (H₄). Stages of spraying were arranged in the main plot, and different plant growth regulators were applied to sub plot. The 2, 4-D, Flumet, GA₃, NAA were dissolved in 1% ethanol to make 50ppm concentration. The solution of growth regulators (at 50 ppm conc) was applied with a spray to ovaries of bagged female flowers according to the rate of 0.5ml (equal to 25 mg) per ovary. The control ovary was sprayed only with water. Ten ovaries were selected randomly for each of three replicates at first fruiting stage and were treated with each plant growth regulator. All the treated flowers were bagged in the afternoon one day before anthesis, and rebagged after application of hormones for 3-4 days to prevent open pollination. Data on ovary length (mm), ovary diameter (mm) were taken at just before and 5,10 and 15 days after spraying (DAS), fruit weight after 15 days after spraying and fruit set percentage were also calculated. The data were analyzed statistically and mean separation by DMRT.

Achievement/Findings:

In the present findings, among four growth regulators, 2,4-D showed better effect on growth and fruit set as compared to fulmet, GA₃ and NAA probably due to its capacity to induce parthenocarpy in kakrol. The overall result revealed that 2,4-D applied at anthesis showed better performance over others in parthenocarpic fruit development of kakrol.
