《南方丝瓜杂交制种高产栽培技术》

南方丝瓜杂交制种高产栽培技术

丝瓜是夏秋季南方地区主要的瓜菜类品种，深受消费者欢迎。长期以来，丝瓜种植一直处于分散、零星状态，优良品种难以得到大面积的繁育推广，产量低、效益差。为解决这个问题，广西贺州市农科所连续10年进行丝瓜密植制种高产栽培技术研究，获得了丰富的栽培管理经验，使每667平方米种子产量从原来的10千克增加到60千克～75千克，最高时达90千克，每667平方米收益从600元增加到现在的4000多元。现将其技术介绍如下。

一、选择制种良种。进行繁育丝瓜制种以增加株数来提高产量，但又不能过密。因此必须选择主蔓结瓜性好、坐瓜节位低、坐果率高、抗病性强、抗高温的系列品种，如广东市场上最高产的丝瓜品种绿胜系列。

二、适时播种。为使花期相遇，通常将熟期相同的父本较母本提前播种7～10天。父母本的栽培管理与商品瓜栽培相同。父本播种时间在3月15日，母本适当延期。因早春气温低，丝瓜直播发芽率低，必须催芽露白后才能播种，育苗可用营养钵育苗或小拱棚育苗，关键是丝瓜苗一定要在出第一张真叶前移栽，否则会影响成活率。播后4～5天出苗，出苗后3天即可定植。露地种植丝瓜畦面包沟宽170厘米，双行“品”字形种植，每穴2苗，穴距75厘米，密度为每667平方米2300～2500苗。定植时穴施农家肥0.5千克，复合肥少量。

三、肥水管理。良种丝瓜前生育期短，植后30～40天结瓜。丝瓜苗有10厘米长时，每667平方米施农家肥500千克和氮、磷、钾

Abstract

Dried loofah gourd (Luffa cylindrica L., M.J. Roem, syn. Luffa aegyptiaca Muell) seed were harvested and divided in two samples, viz., hull and dehulled. The samples were analyzed for proximate composition and mineral contents (Mg, Ca, Na, K, Fe, Cu, Zn and Mn). Tannin, oxalate, phytin phosphorus and phytic acid were the antinutritional factors evaluated. Some functional properties, such as oil absorption capacity (OAC), water absorption capacity (WAC), foaming capacity (FC), foaming stability (FS), emulsion stability (ES), least gelation concentration (LGC) and bulk density, were also investigated. The dry matter, crude protein and ether extract values were significantly higher (P<0.05) in the dehulled loofah gourd seed meal (DSLGM) than in the hull sample (HLGSM), while the crude fibre, carbohydrate and ash contents were lower (P>0.05). DLGSM was significantly lower in phytin phosphorus and oxalate but higher in tannin content (0.41%) than HLGSM with coefficient of variation (CV) of 20.79, 40.49 and 12.35% respectively. The phytic acid content in samples did not differ significantly (P>0.05). Contentrations of Mg, Ca, Na, Fe, Cu and Mn were significantly higher but Cu and Zn were lower in DLGSM. The highest coefficient of variation (59.65%) was recorded by Zn, followed by Mn (43.30%), Na (30.50%) and Ca (20.66%). There was no significant difference in the K values for DLGSM and HLGSM (P>0.05). The functional properties measured, such as OAC, EC, FS, ES and LGC, were not affected significantly. However, WAC and FC increased significantly (P<0.05) with CV of 30.01 and 33.22% while the bulk density was not affected (P<0.05). These values obtained for the DLGSM indicate the potential in its use as a source of vegetable protein in animal and human nutrition.

Key words: Luffa cylindrica, proximate composition, antinutritional factors, mineral contents, functional properties.

Introduction

Protein is one of the important nutrients required for growth and production in man and livestock. One of the cheap sources of protein for both man and livestock is the grain legumes, many of which had been evaluated to be of good nutritional values when used in formulating diets 1, 2. The competition for most of the legumes that are good quality sources of protein continually makes the search for other veritable sources inevitable such as African yam bean 3, Manihot glaziomy 4, Cannavalia ensiformis 5 and Caesalpina pulcherima 6.

Luffa cylindrica (L., M. J. Roem, syn. Luffa aegyptiaca Muel) is a crawling plant that grows in the wild and on abandoned building structures and fence walls in towns and villages in Nigeria. The sponge in the whole fruit holds the seeds, as many as 25-30 together. The sponge is used in the rural areas of the Southwestern Nigeria for washing and scrubbing of household utensils while the seeds are discarded. There is scarce information on the functional and physico-chemical properties of most of the vegetable proteins that are of less importance in animal nutrition and which are potentially good for use in livestock feeds. These properties, such as texture, solubility, water absorption capacity, oil absorption capacity, foaming capacity, gel formation, etc. are indices that may be used to a large extent to predict the behaviour of the plant protein in food formulations 7-9. In separate studies, Kinsella et al. 10 and Oshodi et al. 11 reported some functional and physicochemical properties for soy protein and benth (Adenopus breviflorus) seed protein concentrate respectively. This study was carried out to evaluate the chemical composition of loofah gourd seed and to provide necessary information on the

physicochemical characteristics with a view to its use in animal and human foods.

Materials and Methods

Seed collection: Dried loofah gourds were harvested during the months of January to March in Ikorodu, Ado-Ekiti, and Ikere-Ekiti towns all located in the South Western Nigeria. The gourds were broken opened and the sponge removed. They were shaken to remove the seeds from the fibre mesh of the sponge manually. The seeds were further sun dried and kept in jute bags from which samples were taken for analysis.

Proximate composition and mineral analysis: Raw samples of loofah gourd seed were taken and divided into two. One sample was dehulled while the other half was not. The two samples were ground in the Laboratory Hammer mill (DIETZ, 7311 Dettingen- Teck, West Germany) and stored in dried sample bottles. The samples were then analyzed in triplicate for proximate composition according to AOAC 12.

The crude protein was obtained by multiplying the nitrogen value by a factor of 6.25 while the nitrogen-free extract (NFE) was determined by difference.

Mineral analysis was carried out both on the dehulled and hull samples. The Ca, Mg, Fe, Zn, Mn and Cu were determined using the wet digestion procedure. The samples were digested with a mixture of nitric, sulphuric and hydrochloric acids. The atomic absorption spectrophotometer (Buck Scientific, East Norwalk, CT06855, USA) was used to determine the values for each of the
