BACKGROUND Flowering synchrony and floral sex ratio have the potential to influence the mating opportunities and reproductive success through female function. Here, we examine the variances in synchronous display of female and male function, ratio of male to female flowers per day and subsequently reproductive output in small populations of two monoecious plants, Sagittaria trifolia and Sagitta...

Flushing, i.e. cyclic fluctuations in fruit yield, is an important problem in sweet pepper production. These fluctuations result from cyclic variations in fruit set. Therefore, the relationship between fruit set and plant sink and source strength was investigated in several greenhouse experiments. A decrease in plant source strength by decreasing inter-plant distance or light intensity or by le...

Plasticulture studies were continued on bell pepper. Total marketable fruit yields of 4.85, 3.94 and 3.09 tons per acre were obtained from plants grown on silver, white, and black plastic mulches, respectively. Number of fruits produced per plant followed the same trend. Individual fruit weights of 85-117g were not significantly different among treatments. Fruit set as indicated by number of fr...

The effect of pre-sowing magnetic treatments was investigated on germination, growth and yield of okra (Abelmoschus esculentus cv. Sapz pari). The dry okra seeds were exposed to sinusoidal magnetic field induced by an electromagnet. The average magnetic field exposure was 99 mT for 3 and 11 min and seeds with no magnetic field treatment were considered as control. Both treated and non-treated s...

A field experiment was carried out at Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh, to assess the effect of different plant growth regulators on tomato during summer season 2011. Different plant growth regulators (PGR) viz. PGR = Control, PGR = 4-CPA (4-chloro phenoxy 0 1 acetic acid) @ 20 ppm, PGR = GA (Gibberellic Acid) @ 20 ppm and PGR = 4-CPA + GA3 @ 20...

An experiment was conducted to manage the eggplant (brinjal) shoot and fruit borer Leucinodes orbonalis Guenée (Lepidoptera: Crambidae), the leafhopper Amrasca biguttula biguttula (Ishida) (Hemiptera: Cicadellidae), and the whitefly Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) during kharif, the southwest monsoon season (Jul-Oct), in 2010 and 2011 at an experimental farm at the Division ...

For several plant species, brood size results from the abortion of ovules and seeds. However, these processes have rarely been studied together in wild plants. In some of the leguminous species studied, seed abortion has been found to depend on pollen quality and on the position of the ovule or fruit. The direct consequence for the mother plant is that fruit costs increase as the seed:ovule rat...

the current experiment was carried out to evaluate qualitative and quantitativeof three melons (cucumis melo gp. ameri) accssions named zardjalal, ananasi and khanoti. the experiment was conducted in a randomized complete block design (rcbd) with 16 treatments and three replications at research field of jahad-e-daneshgahi, campus of agriculture and natural resources, university of tehran. five ...

Reproductive ecology of Agalinis acuta was investigated by examining potential for self-fertilization before and at anthesis, reproductive output from outcrossed vs. selfed matings, and effects of browsing, plant size, and conspecific plant density on seed and fruit production. These features of a plant species can provide indirect information pertinent to conservation such as patterns and main...
