John(约翰) Stommel() of(of) the Agricultural Research(农业研究) Service() of(of) the US(美国) Department() of(of) Agriculture(农业) (USDA-ARS)((USDA-ARS)) has(has) investigated(研究) the desirability(可取性) for(for),(,) and() practicality(实用性) of,(of,) producing(生产) snack(小吃) peppers(辣椒),(,) both(both) sweet(甜味) and() hot(),(,) with(with) low() seed(种子) count(计数).(.)
His() findings(研究结果) are(are) in(in) the article(文章),(,) "(")Reduced(减少) Seed(种子) Count() Improves(改善) Versatility(多功能性) and() Propagation(传播) of(of) Small()-()fruited(水果) Peppers(辣椒) ((()Capsicum(annuum) annuum() L.)(L.)) for(for) Specialty() Markets(市场),"(,") published(发表) in(in) HortScience.(HortScience.)
Small()/(/)miniature(小型) sweet() and() hot peppers(辣椒),(,) such(such) as() snack(小吃) peppers(辣椒),(,) are() a(一种) rapidly(快速) growing(增长) class() of(of) specialty() peppers(辣椒).(.) As(As) with(with) grapes(葡萄) and() watermelons(西瓜) and() certain(某些) other(其他) fruits(水果),(,) low() seed(种子) count() is() an(an) important(重要) attribute(因素) for(for) consumer(消费者) acceptance(接受) of(of) small()-()fruited(果的) specialty(特产) peppers(辣椒).(.) But(但是),(,) this(这一) attribute(属性) is() understandably() counterproductive(适得其反) in terms of(依据) maintaining(保持) a(a) strong() continuous(连续) yield(产量).(.)
Environmental(环境) stress(应力) conditions(条件),(,) including(包括) high(高温) or() low temperature(低温),(,) humidity(湿度),(,) high() or() low(低温) light() intensity(强度),(,) heavy() rain() or() drought(干旱),(,) and() even(甚至) strong wind(强风),(,) negatively(负面) affect(影响) the quality(品质) of(of) fruit(果实) and() growth(生长).(.) These(这些) conditions(条件) can(可以) also() induce(诱导) fruit(果实) to(to) be(be) seedless(无籽) or() with(with) significantly(显著) reduced(减少) seed(种子).(.)
This() is() known as(被称为) parthenocarpy(单性结实),(,) the development(发育) of(of) a(a) fruit(果实) without(没有) prior() fertilization(受精).(.) In(In) parthenocarpy(单性结实),(,) the ovary(卵巢) is(is) stimulated(刺激) even(即使) without(没有) pollination(授粉) and() thus(因此) fruit(果实) development(发育) begins(开始) without(没有) fertilization(受精).(.) Some(一些) of(of) this() occurs(发生) naturally(自然),(,) as() with(with) bananas(香蕉),(,) pineapples(菠萝),(,) and() persimmons(柿子),(,) to(to) name(仅举) but() a(a) few(few).(.) Other(其他) examples(例子) are() a(a) result(结果) of(of) thoughtful(思熟虑) intervention(干预).(.)
Induction(诱导) of(of) parthenocarpy(单性结实) is() a(a) common(常见) agricultural(农业) practice(实践) for(for) some(一些) horticultural crops(园艺作物).(.) Selective(选择性) breeding(育种) for(for) parthenocarpy(单性结实) has(has) demonstrated(证明) the utility(效用) of(of) seedlessness(无籽) for(for) improved(提高) yield(产量) and() quality(质量) in(in) selected() environments(环境).(.)
Small() sweet peppers(甜椒) are(are) popular(欢迎) among(among) consumers(消费者) because() of(of) their() versatility(多功能性),(,) snackability(snackability),(,) vibrant(鲜艳) colors(色彩),(,) and() nutrition(营养) attributes(属性).(.) Mature(成熟) peppers(辣椒) comprise() the majority(大部分) of(of) the snack(小吃) pepper(辣椒) market(市场) segment(片段) due to(由于) enhanced(增强) sweetness(甜味) and() the aroma(香气) of(of) ripe fruit(成熟水果).(.)
Although(虽然) characteristically(特色) pungent( 刺激),(,) no-(no-)heat() habanero(哈瓦那) cultivars(品种) within(within) the snack(零食) market(市场) class() provide(提供了) unique(独特) fruity(果味) and() floral() attributes(属性) of(of) the habanero(哈瓦那) without(没有) fruit(水果) pungency(刺激性).(.)
Seasonal(季节性) field(田间) production(生产) is(is) supplemented(补充) by() year-round(全年) greenhouse(温室) production(生产).(.) Although(虽然) field(田间) production(生产) of(of) traditional(传统) pepper(辣椒) commodities(商品) is(is) in(in) decline(下降) in(in) parts(部分) of(of) the country(),(,) other(其他) segments(部分),(,) including(包括) snack(小吃) peppers(辣椒),(,) are(are) expanding(扩大) greenhouse(温室) acreage(面积) for(for) high()-()value(价值) pepper(辣椒) production(产量).(.)
A(A) relatively(相对) small() number(子数) of(of) commercial(商业) snack(小吃) pepper(辣椒) cultivars(栽培品种) have(have) been(been) developed(开发),(,) many(许多) of(of) which(其中) lack(缺乏) uniformity(均匀性) and() quality(质量) attributes(属性) such as(例如) low() seed() count(计数),(,) which(which) enhances(增强了) culinary(烹饪) convenience(便利) for(for) product(产品) end users(最终用户).(.)
True(真实) breeding(育种) pepper(辣椒) lines(品系) selected(选择) for(for) reduced(减少) fruit(果实) seed(种子) count() exhibited(表现) significantly(显著) reduced(减少) seed(种子) count() relative(相对) to(to) breeding(育种) lines(品系) with(with) seed(种子) set() typical(典型) for(for) pepper(辣椒).(.)
